3 Section 1. Overview The ViewArgonaut software contains individual program modules that let you control the operation, data processing, and testing of SonTek s Argonaut line of acoustic Doppler current meters. More specifically, ViewArgonaut allows you to control the following SonTek instruments. Argonaut-ADV (Acoustic Doppler Velocimeter) Argonaut-MD (Mooring Deployment) Argonaut-SL (Side Looking) Argonaut-SW (Shallow Water) Argonaut-XR (Extended Range) This User Guide uses generic terms such as Argonaut, instrument, or system when referring to any of the above models. When necessary, specific model names will be used. The ViewArgonaut program modules that are available from its Main Menu (Figure 1) include: Diagnostics Module (Section 2) Lets you check your system for proper operation. Recorder Module (Section 3) Lets you download or erase data files from the instrument's internal recorder (if one is installed in your system). Deployment Module (Section 4) Lets you prepare the system for an autonomous deployment. To view the data collected by an autonomous deployment, you will have to use the Processing module after the data has been collected. Realtime Module (Section 5) Lets you prepare the system for a real-time deployment, and allows you to view the data live. Processing Module (Section 6) Lets you view, manipulate, and export data during postprocessing. Your original data files are not altered. Figure 1. ViewArgonaut Main Menu 3

4 To begin using ViewArgonaut: Connect the Argonaut to the PC and apply system power (not needed for Processing). Start ViewArgonaut (Start Programs SonTek Software ViewArgonaut). Select the module you wish to run (Diagnostics, Recorder, Deployment, Realtime, Processing). SYSTEM MANUAL NOTE Throughout this manual, you are often referred to the System Manual for your particular instrument. In many cases, you can access the Help menu within many of the ViewArgonaut program modules to access a link to each System Manual. In these cases, when you click on the Argonaut-XX manual menu item (where XX is the abbreviation for a system type; e.g., MD, SL, SW, XR), the program will open the PDF version of the System Manual using Adobe Acrobat. If the Help menu does not contain a link to your System Manual, you can instead use the PDF version of the manual that was included on the CD-ROM distribution disk that was included with your system. 4

5 Section 2. Diagnostics Module ViewArgonaut User Guide Note: All functions in ViewArgonaut s Diagnostics module can be accessed using the Beam- Check module in SonUtils. The SonUtils BeamCheck module also has additional features and capabilities not available in Diagnostics; we encourage you to use BeamCheck when possible. The Diagnostics module (Figure 2) is a useful system evaluation tool for all Argonaut, Flow- Tracker, and Triton systems. Additionally, Diagnostics can be used to survey deployment sites for the Argonaut SL, SW, and XR systems. You should become familiar with the operation of this module it is a valuable tool for understanding how your system works. Diagnostics Module Overview Diagnostics Module Operation Diagnostics Module Output Deployment Site Survey System Diagnostics 2.1. Diagnostics Module Overview Diagnostics is the same program used by SonTek technicians. It provides you with a powerful tool for understanding and verifying system performance. The output of Diagnostics is a plot of signal strength versus range from the instrument. This is used to determine the effective measurement range of the system and to look for interference from boundaries and underwater structures. As such, you can use Diagnostics to survey a deployment site (see Deployment Site Survey). Figure 2. Diagnostics Module Main Screen 5

6 We recommend that you become familiar with Diagnostics and use it on a regular basis during data collection. Using Diagnostics to test the system before every experiment can identify problems that might otherwise be undetected, thereby reducing the potential for lost or corrupt data (see System Diagnostics). The program samples the return signal at several points within the total measurement range. The total measurement range depends on system type and frequency kHz SL: 120-m range kHz SL: 50-m range MHz SL or XR: 20-m range MHz SL or XR: 10-m range MHz SW: 6-m range Signal strength data (Sig Amp) are given in internal units called counts; one count equals 0.43 db. Sine and Cosine data are given in internal units; these have no direct application for the customer, but are used for internal diagnostic procedures at SonTek Diagnostics Module Operation To run Diagnostics: For ideal testing conditions, mount the system at the site where you will conduct your experiment. Alternatively, mount the system in an open body of water for general diagnostics. Connect the instrument to your computer and apply power to the system. Refer to your 888System Manual for interconnection details. Start ViewArgonaut (Start Programs SonTek Software ViewArgonaut). Click Diagnostics on the ViewArgonaut menu. Click Connect to display the Communications window. If necessary, select the COM port to which the instrument is connected and the appropriate baud rate (default = 9600). Click the Go! button. Table 1 lists the Diagnostics module s program controls. Table 2 describes the Diagnostics displays. Upon execution, the software does the following. Establishes communication with the instrument and downloads system operation parameters. Note: If the program fails to connect to the instrument, check your communication settings and cable connections; details can be found in your 8888System Manual. Starts the special Diagnostics operating mode. Initializes a continually updating display of signal strength versus range from the transducers. The display is updated about once every five seconds. See your 9999System Manual for information about the displayed signal strength profiles. Diagnostics includes the ability to record the displayed data to a file. Recording data provides a record of system performance. SonTek customer support may request a recorded Diagnostics file. Diagnostics data is a very effective way to evaluate system performance. To record data to an ASCII file: - Click the Log Diagnostic Values to File icon. Select a folder and file name for the data (a.ckg file extension is automatically added). - Click OK to start data recording. Click Close Diagnostic Log File to stop data recording. When sending data to SonTek for analysis, record at least 10 to 20 profiles for reference. 6

7 Table 1. Diagnostics Module Program Controls Control Description Connect Opens the Communications window, which allows you to establish PC-to-instrument communications. Pause-Stop Pauses the display of data. Click again to resume display updates. Open Existing Diagnostic Allows you to select and display a previously recorded diagnostics Log File data file (.ckg). Log Diagnostic Values to Allows you to save diagnostics data to a file (.ckg) for later playback and review. This file can also be sent to SonTek/YSI for File (i.e., Save File) troubleshooting assistance. Close Diagnostic Log File Stops the recording of a data file that was opened with Save File. Print Sends display data to a printer. Copy Sends the display data to the clipboard for use in other programs. Help Opens the on-line help file (or press F1). Step Forward/Backward Lets you review a series of pings. Zoom X / Zoom Y Lets you change the plot axis scales. Note: Only available for use with Argonaut-ADV and Triton systems. Averaging Lets you plot a running average of sequential pings. This can be very useful in removing the natural variability in successive samples. The display will be a running average of pings until this button is pressed a second time. Close Exits the Diagnostics program module. Display Ping # Noise Cos Min/Max and Sin Min/Max Peak Pos Peak Level Sig Amp Sine and Cosine Table 2. Diagnostics Module Displays Description Identifies the currently displayed ping. Shows the electronics noise level for each beam, which is determined by the signal strength when the instrument is not receiving any return reflection from the water. This should match the signal strength for the flat portion of the graph beyond the boundary. Used for factory diagnostics at SonTek and are not described here. This is the location of the center of the peak for the sampling volume for each beam. The position should be approximately the same for each beam; variations of 5-10 counts are typical. This is the height of the peak of the sampling volume for each of the beams. This will vary depending on the amount of scattering material in the water. Shows a representation of the strength of the returned signal. See your 99991System Manual for descriptions of how to interpret this data. Used for factory diagnostics at SonTek and are not described here. 7

8 2.3. Diagnostics Module Output ViewArgonaut User Guide For an example of program output interpretation, refer to your instrument s 11111System Manual Deployment Site Survey Surveying the deployment site is typically only done for Argonaut-ADV/SL/SW/XR and Triton systems, and not for Argonaut-MD or FlowTracker systems. There are two main goals of a deployment site survey. To verify that the system is not seeing interference from underwater structures, deployment lines, or boundaries (e.g., surface, bottom, channel walls). To set the limits of the measurement volume based on the environment Acoustic Interference It is important that the instrument does not see any interference from underwater objects whose reflections may contaminate the acoustic return signal (and as such, affect velocity data). These objects may be underwater structures, boundaries (surface, bottom, channel walls), or smaller items such as deployment lines and cables. Any large objects within the measurement field will show up as spikes in the Sig Amp return signal. These spikes may be present in one or more of the instrument s beams. If any spikes are present in some portion of the measurement volume, velocity data will be contaminated to some degree. The acoustic return signal for each sample is highly variable, and as such, it is useful to store a number of pings to an output file (Log Diagnostic Values to File icon) and look at the mean profile to determine any consistent source of interference. When working near underwater structures or deployment lines, interference can come from direct reflections or from flow distortion caused by the object. To the greatest extent possible, place the instrument s measurement volume in an open-water area free from sources of acoustic or flow interference Measurement Volume Limits In open water, the maximum effective range for the SL, SW, and XR is determined by the distance at which the signal strength approaches the noise level. For most environments, the signal strength will be above the noise level out to the maximum allowed instrument range. In clear water, signal strength may approach the noise level before reaching the maximum instrument range. This can be seen clearly from the output of the Diagnostics module. Capturing a number of pings using the output file option (Log Diagnostic Values to File icon), and plotting the mean signal strength versus range, allow you to directly measure the maximum range. During normal operation, the SL, SW, and XR will automatically end the measurement volume if the signal level is less than 6 counts higher than the noise level. This is to prevent contamination if the signal strength levels are not sufficient. For example, if the end of the measurement volume is set by the user to 15 m, but signal strength is only sufficient to a range of 13 m, the system will automatically end the measurement volume at 13 m. The precise start and end of the measurement volume is reported with each sample. When working near boundaries or underwater structures, the limits of the measurement volume are set by the range at which the system sees the reflection from the boundary. You must set the measurement volume limits to avoid any contamination from the boundary reflection. The ex- 8

9 ception to this is when using either an up-looking SW or XR with dynamic boundary adjustment see the 11111System Manual for details. The end of the measurement volume should be placed no closer than the greater of 0.25 m and 10% of the total range to the boundary. If there is any variation in boundary range or instrument mounting, the end of the measurement volume should be placed to avoid interference at all times System Diagnostics When looking at the output data, there are four basic features to verify system operation signal strength profile, noise level, boundary reflections, and sine/cosine data Signal Strength Profile When looking at the signal strength profile, data from all active beams should be similar in magnitude and shape. Note that with two-beam systems (e.g., Argonaut-SL, SW) or probes (e.g., 2D vs. 3D), the third beam is still plotted but will show a constant signal strength at the noise level (see your 11111System Manual for examples). For systems with a vertical beam for stage, data from the vertical beam will also be plotted but will likely show a significantly different profile since that beam is looking vertically up at the water surface. Each beam should see initial signal strength of roughly the same magnitude and should decay at the same rate. Check that all beams have an unobstructed view and are not showing spikes from objects in their path. When looking at the output data, keep in mind that individual samples will vary significantly from ping to ping. Look for features that are consistent over several pings. It is often helpful to record a number of pings and plot the mean profile to look for consistent features in the data Noise Level The system noise level for each beam is measured as part of the Diagnostics data collection process. You can read the system noise level from the data at the top of the screen (Noise). Examples of typical noise levels (in counts): SW SL(all), XR(all), and MD (3-MHz) MD(deep-water titanium 1.5-MHz) Argonaut-ADV and Triton FlowTracker (can vary system to system, but should be consistent day-to-day for any given system) The noise will vary slightly among different beams. If the noise level of any one beam is outside this range, this can be an indicator of a noisy environment or of problems with the system. Try moving the system away from any motors or electronics to see if the noise level changes. If problems persist, contact SonTek Boundary Reflection If the instrument has a boundary (surface, bottom, wall, underwater structure) within the measurement range, this boundary should be seen as a strong spike in the return signal profile. In most cases, all beams will see a reflection of about the same magnitude at the same range. In certain locations, the magnitude and location of the boundary reflection will vary between beams due to the different beam mounting angles and the nature of the boundary reflection. If the system is tested in very shallow water, it may show multiple boundary reflections with increasing range. 9

10 Sine/Cosine Data ViewArgonaut User Guide These data have no direct interpretation and are provided for factory diagnostic purposes only. They will typically show a mean level throughout the profile of about 125 counts, with a small amount of variation around that level. The amount and nature of the variations depends on the environment. The only reason to be concerned is if these data show a flat line with no variations. This indicates that something in the electronics is not functioning properly. Contact SonTek if you see this when running diagnostics (with the transducer either in or out of the water). 10

11 Section 3. Recorder Module ViewArgonaut User Guide The Recorder module (Figure 3) is used to extract data from your instrument s (optional) internal recorder. This program can also be used to format (i.e.; erase) the internal recorder. The Recorder screen display has three main areas: Communications Display (left side panel) Lets you quickly set up and view the computerto-instrument communications interface. Recorder Display (right side panel) Lets you set up and control the downloading of recorder data and the formatting (erasing) of the recorder. Menu Bar (top row) Lets you access controls using a mouse or keyboard shortcut keys Recorder Module Quick Start Instructions The basic steps for using Recorder are as follows: a.

The settings last used by Recorder are automatically saved in the Recorder.cfg file. Help - Help Topics Opens the help file. - About Recorder Displays program copyright and version information Recorder Data Retrieval Rates The rate at which data can be retrieved (downloaded) from the recorder depends on a few factors such as cable length, baud rate settings, and computer hardware. 13

14 For short cables (less than 30 m), the default extraction rate of baud provides the fastest downloading time. For longer cables, a slower baud rate may be needed to ensure reliable communication. If Recorder encounters several communication errors while retrieving data, it will terminate the retrieval. Note that some computers (particularly older laptop computers) do not operate reliably at high baud rates and may not be able to work using the default setting of If you encounter data extraction problems, run the Recorder module using a lower data extraction rate. Table 3 shows the typical download rates achieved with different baud rate settings. Extraction rates slower than 9600 baud are rarely needed and are not shown here. Actual retrieval rates may vary depending on the environment and the type of computer used. Table 3. Baud Rate Comparison Rate Effective Rate (bps) Time for 1MB (minutes)

15 Section 4. Deployment Module ViewArgonaut User Guide The ViewArgonaut Deployment software follows the popular wizard style interface, using a sequential series of screens to configure all required parameters. One such screen, with additional annotations, is shown in Figure 4. A few of the features of the Deployment software are listed below. The software can be used three different ways: - Planning a deployment without actually being connected to an instrument. - Loading desired parameter settings to an instrument without starting a deployment. - Loading settings and starting a deployment. An index of all steps in the deployment process is shown on the left side of each screen. You can move between steps using the Back and Next buttons. - You can also move between steps by clicking on the desired step within the index. - IMPORTANT: Be aware that many of the steps in the index consist of more than one screen. Using the index to move between steps could potentially cause you to miss one or more screens with important system parameters. Each screen displays parameters related to a specific aspect of data collection. The software automatically creates a log file each time you connect with an instrument. This provides a record of commands sent to, and responses from, the instrument for the entire deployment procedure. Log files are stored within a Log Files subdirectory of the ViewArgonaut program folder (normally C:\Program Files\SonTek\ViewArgonaut\Log Files). They use a naming format containing the date they were created and a sequential number so that no log files are overwritten. The typical deployment procedure is to move through each screen in order, while setting and verifying all commands. The final part of the deployment software ( 4.10) allows you to: - Save all settings to a template file (on your computer) for future use. - Upload settings to the instrument and save them to internal (non-volatile) memory. - Start data collection. Screen Heading Deployment Software Index System Operating Parameters Figure 4. Typical Deployment Software Screen 15

16 4.1. Creating Template Files The Deployment software uses template files to store all system hardware and operating parameter settings. Template files are specific for a given system type, frequency, and configuration. You can create multiple template files for a given system. You can use a template file for multiple systems of the same type and hardware configuration. This can be useful when applying the same operating parameters to different systems in different locations. No sample template files are included with the Argonaut software, but they can be easily created for your system using the following steps. Connect the system to an available serial (COM) port on your computer. Connect the system power supply. Run ViewArgonaut and click Deployment on the main menu. Follow the procedure outlined in 4.2 for connecting to the system. Set the operating parameters for your application as outlined in 4.3 through 4.8. At the Deployment Summary screen ( 4.10), click Save Configuration to File. The software will prompt you for a file name and location in which to save the template file. - The default template folder (when using the standard ViewArgonaut installation procedure) is C:\Program Files\SonTek\ViewArgonaut\Templates. - Files stored in this folder will automatically be listed by the Deployment software during the Load Deployment Template step ( 4.2). - Template files can also be stored in another folder if desired Starting or Planning the Deployment Process The deployment process is very similar whether you are connecting directly to a system or just planning a deployment using a template file. Preliminary If you will be connecting directly to a system: - Connect the system to an available serial (COM) port on your computer. - Connect the system power supply. Run ViewArgonaut and click the Deployment button on the main menu. The first Deployment screen (Select Session Type; Figure 5) gives you two choices: - Direct system setup Lets you connect directly to a system to plan or start a deployment. Clicking Next takes you to the screen (Figure 5) that begins the communications process. - Plan a deployment Lets you plan a deployment using an existing template file without connecting to the instrument. Clicking Next takes you to the screen (Figure 6) that lets you select the template file to use. If you chose Direct system setup, establish communications with the system (Figure 7): - Select the correct serial (COM) port and baud rate for your system. - Click Connect To System. - The software will display progress as communications are established and all system settings are downloaded. - When all communications are done, click Next to view the hardware configuration settings that were loaded (Figure 8). 16

17 Figure 5. Deployment Software: Select Session Type Figure 6. Deployment Software: Connect to System 17

18 If you chose Plan a deployment, you will be prompted to select a template file (Figure 7). - Files in the default template folder (C:\Program Files\SonTek\ViewArgonaut\Templates) will be listed in the main window. - To load a file from another location, select Load from file and click Open File to browse for your desired template file. - When you have selected the desired template file, click Next to view all the major hardware configuration settings for this system (Figure 8). Figure 7. Deployment Software: Load Deployment Template Figure 8. Deployment Software: Show System (Hardware) Settings 18

19 When connected directly to a system, you can proceed in two ways on the Load Deployment Template screen (Figure 9): - Select Use existing system settings to work with settings downloaded from the system. - Select Load from file or Select a Template below to work with settings from an existing template file and apply those settings to the current system. Files in the default template folder (C:\Program Files\SonTek\ViewArgonaut\Templates) will be listed in the main window. To load a file from another location, select Load from file and click Open File to browse for the desired template file. When loading a template, the hardware settings in that template must match the hardware settings of the current system, or the template file will not be loaded. When ready to continue, click Next. All system parameters can be entered in either English Units or Metric Units, as chosen in the Select Unit System and Options screen (Figure 10). - This also affects the output units used for any real-time output data (RS-232 or SDI-12). The checkboxes on right side of the screen let you show/hide various parameter settings. - We recommend reviewing all installed parameter settings before each deployment. Show Profiling Settings ( 4.4) Show Advanced Settings ( 4.5) Show Flow Settings ( 4.6) Show SDI-12 Settings ( 4.8) - Any parameters that are not reviewed will not be changed from their current settings. When ready, click Next to start setting all necessary parameters. Figure 9. Deployment Software: Load Deployment Template File or Use Existing Settings 19

20 4.3. Standard Operating Parameters Standard operating parameters are those settings required for most Argonaut systems and deployment types. These parameters are divided between two screens (Figure 11 and Figure 12). PARAMETER DEFINITIONS: Refer to your 11System Manual and its Direct Command Interface section (usually Appendix C) for examples and details about how these parameters are used with your Argonaut system. Detailed explanations are not provided here because the parameters may function differently for your particular Argonaut system. As an aide, the parameter s Direct Command reference is shown in [brackets]. The first screen (Figure 11) presents the following parameters (see Parameter Definitions). After all parameters are properly set, click Next. File Name [Deployment] Start Date [StartDate] Start Time [StartTime] Comments [Comments] Figure 10. Deployment Software: Select Unit System and Options The second screen (Figure 12) presents the following parameters (see 1Parameter Definitions). After all parameters are properly set, click Next. Averaging Interval [AvgInterval] Sampling Interval [SampleInterval] Def Water Salinity [Sal] Cell Begin [CellBegin] Cell End [CellEnd] Dynamic Boundary Adjustment [DynBoundAdj] 20

22 4.4. Multi-cell Profiling Parameters ViewArgonaut User Guide Multi-cell profiling parameters are only required when the profiling feature is enabled. The parameters are displayed on one screen, shown in Figure 13. The screen presents the following parameters. (see 1Parameter Definitions). After all parameters are properly set, click Next. Profiling Mode [ProfilingMode] Blanking Distance [BlankDistance] Cell Size [CellSize] Number of Cells [NCells] When looking at the graphic display comparing the multi-cell profile to the single integrated cell (determined by Cell Begin and Cell End), it is important to remember that the single integrated cell will be adjusted with changing water level if Dynamic Boundary Adjustment is set to YES (see Figure 12). The location of multi-cell data is fixed, and will not be adjusted with water level. Figure 13. Deployment Software: Profiling Settings 22

23 4.5. Advanced Operating Parameters ViewArgonaut User Guide Advanced operating parameters are present on all Argonaut systems, but are not commonly used. These parameters are most commonly left at their default values except for specialized applications. These parameters are divided between two screens (Figure 14 and Figure 15). The first screen (Figure 14) presents the following parameters (see 1Parameter Definitions). After all parameters are properly set, click Next. Temperature Mode [TempMode] Default Water Temperature [Temp] Coordinate System [CoordSystem] Reverse X Velocity [ReverseXVelocity] Data Format [DataFormat] Enable Flow Display [AutoSleep] PowerPing [PowerPing] One Beam Solution [AllowOneBeam] Ice Detection [IceDetection] The second screen (Figure 15) presents the following parameters. These parameters are all related to burst sampling, which is described in your 11111System Manual (see 1Parameter Definitions). After all parameters are properly set, click Next. Burst Mode [BurstMode] Burst Interval [BurstInterval] Samples Per Burst [SamplesPerBurst] Averaging Interval (this parameter is also shown in standard settings; 4.3) Sampling Interval (this parameter is also shown in standard settings; 4.3) Figure 14.

25 4.6. Internal Flow Parameters ViewArgonaut User Guide Some Argonaut systems are capable of making real-time flow calculations. To do this, additional parameter entries are required (see your 11111System Manual for details about these parameters). Flow calculation parameters are divided into two categories: Parameters to define channel geometry (Figure 16 through Figure 19). In the channel geometry screens, the channel type selection will change the layout of the screen to show the required parameters. The choices are: - Irregular Channel Type - Trapezoid Channel Type - Round Channel Type - Ellipse Channel Type Parameters to determine the mean velocity calculation (Figure 20). Selection of units for total volume calculations (Figure 21). Irregular Channel Type Figure 16 shows the screen for Irregular channel type (usually a natural stream). The following parameters are specified on this screen. Enter the parameters, and then click Next to continue. Select Geometry: When set to Irregular, this parameter will change the layout of the screen to display the appropriate channel geometry parameters for an irregular channel type. Input Dimensions: These are the dimensions for an irregular channel. Enter a minimum of 3 and a maximum of 20 survey points to define the shape of the channel cross-section. - X values (Width) must be entered in increasing order. - First Y value (Elev) must be greater than all other Y values. - Use the cursor keys or mouse to move through the survey point input boxes. - To insert a new point (i.e., a new row ) between existing points, use the Insert key. - To delete an existing point (i.e., remove a row ), use the Delete key.

30 Total Volume Calculations Figure 21 shows the screen for enabling total volume calculations and selecting the output units to be used. Total volume is calculated as the measured flow rate multiplied by elapsed time. The selected output units will affect RS232, SDI-12, and Analog Output data. Select Output Units: Set the output units to be used for flow and total volume. - No total volume output: Volume calculations will not be made. Flow rate in cfs or m 3 /s based on the Units selection. - cfs & acre-ft: Flow rate in cfs, total volume in acre-ft. - gpm & gallons: Flow rate in gpm (U.S. gallons per minute), total volume in gallons. - mgd & gallons: Flow rate in mgd (10 6 U.S. gallons per day), total volume in gallons. - m3/s & m3: Flow rate in m 3 /s, total volume in m 3. - l/s & liters: Flow rate in l/s (liters per second), total volume in liters. - mld & m3: Flow rate in mld (10 6 liters per day), total volume in m 3. Total Volume Criteria: Determine which samples are used for total volume calculations. - Always accumulate flow (default): Every sample is used for total volume calculations. - Add flow to Total Volume when flow: use samples when flow rate: >= a user-specified flow rate. <= a user-specified flow rate. magnitude >= a user-specified flow rate. - Add flow to Total Volume when velocity: use samples when velocity (Vx): >= a user-specified flow rate. <= a user-specified flow rate. magnitude >= a user-specified flow rate. Figure 21. Deployment Software: Total Volume Calculations 30

31 4.7. Analog Output Parameters ViewArgonaut User Guide Analog output parameters are only required for deployments that are using the external analog output converter modules (4-20 ma or 0-5 VDC). To control the analog output modules, the Argonaut uses a special RS232 output format to control the external converter. The firmware can control up to 2 converters at the same time, each outputting separate variables. Analog outputs cannot be used during an SDI-12 deployment. Figure 22 shows the screen for selecting analog output parameters. The following parameters are specified in this screen. See 1Parameter Definitions for details about Analog Output parameters. When all parameters are correctly specified, click Next to continue. Output Type: Select the type of analog output converter that will be connected to the system. - Disabled: No analog output converter will be used. - Current (4-20 ma): The output module creates a current signal from 4-20 ma. - Voltage (0-5 VDC): The output module creates a voltage signal from 0-5 VDC. Output Parameters: The Argonaut can control up to two analog output converters simultaneously one on address 1 and one on address 2. Each converter can represent a separate variable with separate scaling limits. - Parameter: Up to nine different variables can be output as an analog signal. - Min Value / Max Value: Input the minimum and maximum variable values that will correspond to the minimum and maximum analog output limits. - Units: Output units are determined by the selection of English or Metric units (Figure 10), and by the section of Total Volume output units (Figure 21). The output units cannot be changed in this screen. Figure 22. Deployment Software: Analog Output Settings 31

32 4.8. SDI-12 Interface Parameters ViewArgonaut User Guide SDI-12 interface parameters are only required for deployments in which the Argonaut will be controlled by an external SDI-12 data logger. SDI-12 operation fundamentally changes the nature of data collection by the Argonaut. During an SDI-12 deployment, the external data logger controls the timing of each velocity sample. Without a signal from the data logger, the system will never record velocity data. In a standard (non-sdi-12) deployment, the system will not recognize any incoming commands from an SDI-12 data logger. The choice of deployment type (standard or SDI-12) is crucial, as an error in this selection can easily result in the loss of all data. Figure 23 shows the SDI-12 interface parameter screen. The following parameters are specified in this screen. See 1Parameter Definitions for details about SDI-12 operating parameters. When all parameters are correctly specified, click Next to continue. SDI-12 Mode: Chooses whether this will be an SDI-12 deployment. - Turn SDI-12 OFF: Used for a standard deployment. - Turn SDI-12 ON: Used for an SDI-12 deployment. Address: Sets the communication address between the Argonaut and the data logger. Output Format: Always set to SonTek. Multi-Address: Determines if multiple addresses will be used to handle data collected during multi-cell profiling. See 1Parameter Definitions for more details. SDI-12 Output format is set to : Shows whether the output data format is set for English or Metric units. Figure 23. Deployment Software: SDI-12 Interface Parameters 32

33 4.9. Battery Life and Recorder Capacity The Battery and Recorder menu (Figure 24) provides estimates for battery life and recorder capacity during an autonomous deployment. The following parameters are shown on the screen. Battery Type: Two battery type selections are supported. - Argonaut-xx Battery Pack Shows listing of standard Argonaut battery packs. - User Supplied Battery For a user-supplied battery, you must enter the battery voltage and capacity before the software can compute an estimate of battery life. Battery Voltage: This is the nominal operating voltage of the battery, which can be expected to change during the course of the battery s life. Battery Capacity: This is the nominal rating of the battery, in amp hours (A-h). - You must enter the rated capacity of your battery for battery life calculations. - Keep in mind that the capacity of many rechargeable batteries can vary depending on the age of the battery and its charge/discharge history. Battery Capacity Multiplier: This is a safety factor used for battery life calculations. - We recommend a value of 80%. This allows a safety factor to account for cold weather (which can reduce battery capacity) and for changes in battery voltage with time. - For deployments in very cold environments, a lower value may be needed. Power Consumption: The software determines this value based on system type, hardware configuration, and operating parameters. It is an approximate value that can vary slightly from system to system. Figure 24. Deployment Software: Battery Life and Recorder Capacity 33

34 Duty Cycle: This is the percentage of time the system is actively collecting data, based on sampling parameters (Averaging Interval, Sample Interval, and Burst parameter if enabled). - The system will normally enter a low power state between samples to conserve power and extend battery life. - Note that duty cycle is always 100% for an SDI-12 deployment. This is because the data logger, not the Argonaut, controls the timing of velocity samples. Also, the Argonaut does not enter a low power state between samples so it can respond to commands from the data logger. - Likewise, the duty cycle is always 100% if Enable Flow Display is YES (Figure 14). This is because the Argonaut does not enter a low power state between samples in order to be able to respond to requests from the Flow Display. - For more information on duty cycle see 1Parameter Definitions. Battery Life: This value is estimated (in days) based on all provided parameters. The basic equation is: Battery life (hours) = (V * Ah * BCM) / (PC * DC) where V = Battery voltage Ah = Battery capacity BCM = Battery capacity multiplier PC = Power consumption DC = Duty cycle Enable Recorder: This is used to turn on or off the internal recorder. - We strongly recommend always recording internal data even when interfacing with an external data logger, as it provides a backup of all data and additional diagnostic data. - If the recorder is full, you will not be allowed to start a new deployment with internal recording enabled. You will need to download the existing data and format the recorder (see below), or disable internal recording. Recorder capacity (Free space is sufficient for ): This is estimated based on the current amount of free space on the recorder and the system operating parameters. - Recorder capacity calculations are based on currently specified operating parameters. - This value may not be accurate for SDI-12 deployments as the external data logger controls the timing of velocity samples. The Show Recorder Details button can be used to view the current contents of the internal recorder, to download data from the recorder, and to format the recorder. An example of the Recorder dialog box is shown in Figure

35 POPPY001 Figure 25. Deployment Software: Show Recorder Details Features of the Recorder dialog box (Figure 25): - A directory of files on the recorder is shown in the main part of the screen. Click on a file to select that file. Hold down the CTRL or SHIFT key while clicking on files to select multiple files. - Using the Browse button to select the destination folder for downloaded files. - Click Download to transfer all specified files. - Click Format to erase the recorder. You will be prompted to confirm your decision; no data can be recovered after the recorder has been formatted. You cannot delete individual files; the entire recorder must be erased at one time. - When done, click Close to return to the Deployment software. 35

36 4.10. Updating Parameters and Starting a Deployment The final step in deploying the Argonaut is to transfer all system settings to the instrument and, if desired, start the deployment. Figure 26 shows an example Deployment Summary screen. This screen shows an overview of the deployment configuration parameters specified in earlier screens. The Save Configuration to File button can be used to create a new template file. - Clicking this button will prompt you to enter a name and path for the template file. - Template files can be used to ensure the same settings are used each time an instrument is deployed. - Template files can also be used to apply identical settings to systems of the same type that are being deployed in different locations. After reviewing the summary, click Next to continue. Figure 26 shows the final screen in the deployment software. This screen is used to transfer all specified settings to the Argonaut, and to start the deployment. The Update System button is used to transfer all settings to the instrument. - All settings are saved to non-volatile memory in the instrument and will not be lost if system power is removed. - Settings can be transferred without starting a deployment if desired. - An updated display will be shown on the screen while settings are transferred. The Start Deployment button is used to begin the deployment. - This button will first transfer all settings to the instrument if it has not already been done using the Update System button. - An updated display is shown on the screen as settings are transferred. Screen Heading Figure 26. Deployment Software: Deployment Summary 36

37 All communications with the instrument are captured to a log file for future reference. The button View Log File can be used to view the log file created with this session. - The software automatically creates a log file each time you connect with the instrument. This provides a record of commands sent to the system and instrument responses for the entire deployment procedure. Log files are stored within a Log Files subdirectory of the ViewArgonaut program folder (normally C:\Program Files\SonTek\ViewArgonaut\Log Files). They use a naming format giving the date they were created and a sequential number so that no log files are overwritten. For standard deployments (SDI-12 mode is NO), you can watch the first few samples generated by the system being output to the screen if desired. After starting the deployment, disconnect the power and communications cable from your computer. Secure the connector and protect it from weather and moisture. The system is now deployed. When you are ready to retrieve/analyze data, see Section 6. 37

You can also use the Connect icon on the toolbar (Figure 44) to open the Communications dialog box. - Note that ViewArgonaut can monitor more than one system simultaneously. Each system must be connected to a unique COM port. - Select the desired COM port and Baud Rate (default = 9600) for the computer serial port to which the desired Argonaut system is connected. - COM port color code: Green = available; Red = in use/not available; Gray = not found. - Click Go!. This should awaken and establish communications with the selected Argonaut system. If not, check your interconnections and COM port settings. If you still cannot establish communications, refer to your 22222System Manual Processing Menu The Processing Menu contains the following options. Sound Speed Correction Lets you correct velocity data for erroneous sound speed that may have occurred due to an incorrect salinity or temperature data. Velocity Coordinate System Lets you select the coordinate system in which to display velocity data. Options are: Beam, XYZ, and ENU. The associated toolbar icon (Figure 44) stays depressed for the selected coordinate system. - Beam Velocity readings are along the selected beam. - XYZ Velocity readings use a Cartesian coordinate system where the X-axis is horizontal and in the direction scribe mark on the probe head or in the direction of the red-tipped transducer (see 22222System Manual for X-axis location details). The Z-axis is upward through the head. The Y-axis is orthogonal to X to complete the right-hand coordinate system. - ENU Similar to XYZ with the Y-axis rotated to North. Velocity readings require a compass or GPS input. E is the East-West reading, with East positive and West negative. N is the North-South reading, with North positive and South negative. U is the vertical up/down reading, with Up positive and Down negative. User Specified Rotation (Figure 41) When activated, lets you rotate all velocity profiles by a user-selectable angle between 0 and 360 degrees.

61 View Menu The View Menu contains the following options: ViewArgonaut User Guide Show Graphs Use this option to select which graph/s will be shown in the display. The default is to Show All Graphs. Selecting any of the other choices will display only that graph (Top or Bottom). This may be helpful when you wish to magnify a particular data set. View Diagnostics Data Allows you to display (Figure 60) expanded diagnostics data (available in Argonaut SL/SW/XR firmware versions 9.5 and later). This data is equivalent to recording a BeamCheck or Diagnostics file periodically during deployment. The standard interval for diagnostics is once every 100 samples. - Diagnostics data from one sample at a time is displayed. Sample number and time are shown at the top. Use the forward/backward icons to move through diagnostic data either 1 or 10 diagnostic samples at a time (Note: Since diagnostic data is normally recorded every 100 samples, 10 diagnostic samples corresponds to 1000 samples in the file). - The two plots show signal strength from the system with range. The top plot shows this profile as raw signal amplitude, and the bottom plot as SNR. These plots can be interpreted as you would for BeamCheck or Diagnostics data (see 33333System Manual). - In the plot: The red line is data from Beam 1. The blue line is data from Beam 2. The green line is data from Beam 3 (if present). The gray line is the theoretical decay profile. This is useful for determining if the signal is behaving normally or showing unusual behavior (see 33333System Manual). - Press the Close button to return to the main ViewArgonaut screen. Figure 60.

The default is to show all toolbars. Selecting any of the other choices will display only that toolbar (File, Processing, or Controls). Show Display Use this option to select which tabular data displays will be shown. Initially, these tabular displays will be shown on the right side of the screen. However, you can use the tabular display s grab bar to drag the display to another part of the screen. For information about each tabular display, see Tabular Data ( 6.2.2). Multi-Cell Data Display Options (Figure 53) Lets you select the way in which multi-cell data are displayed: as speed and direction (Show Speed/Direction), as X and Y velocity vectors (Show Vx/Vy), or a speed/direction vector arrows (Show Arrows). 62

63 Processing Menu The Processing Menu contains the following options: Velocity Coordinate System Lets you select the coordinate system in which to display velocity data. Options are: Beam, XYZ, and ENU. The associated toolbar icon stays depressed for the selected coordinate system. - Beam Velocity readings are along the selected beam. - XYZ Velocity readings use a Cartesian coordinate system where the X-axis is horizontal and in the direction scribe mark on the probe head or in the direction of the red-tipped transducer (see 33333System Manual for X-axis location details). The Z-axis is upward through the head. The Y-axis is orthogonal to X to complete the right-hand coordinate system. - ENU Similar to XYZ with the Y-axis rotated to North. Velocity readings require a compass or GPS input. E is the East-West reading, with East positive and West negative. N is the North-South reading, with North positive and South negative. U is the vertical up/down reading, with Up positive and Down negative. User Specified Rotation When activated (Figure 41), lets you rotate all velocity profiles by a user-selectable angle (0-360 ). The related toolbar icon stays depressed while the selected rotation is in effect. This feature is useful when analyzing current data along a channel. Data Smoothing (Figure 62) Lets you smooth time-series data using a low-pass, adjacentaveraging filter. Two filters are available: uniform weighting (Box Filter) and Gaussian distributed weighting (Gaussian). The amount of filtering can be controlled through the Filter Width and Filter Limits settings. Data Screening (Figure 63) Lets you discard (mask) a portion of a profile using selected criteria. Screening selections include: Discard Range of Samples and Low Amplitude. These selections allow you to set either the starting/ending sample or a threshold. Figure 62. Processing: Data Smoothing Dialog Box Figure 63. Processing: Data Screening Dialog Box 63

64 Mean Removal When activated, this option will subtract the mean from all displayed data. The mean is calculated based on the full range of samples displayed. Data Despiking (Not available this release) When activated, lets you refine readily apparent data spikes into more meaningful data. You select a range of samples over which to interpolate the refining of data based on a user-selected standard deviation. The default window width is 7; the default StdDev is also 7. Sound Speed Correction (Figure 64) Lets you correct velocity data for erroneous sound speed that may have occurred due to an incorrect salinity or temperature data. Flow Calculation (Ctrl+F) Lets you define the parameters used in both the 3D presentation of flow (View Show Cross-Section Flow) and the tabular display of flow (View Show Discharge Summary Display; Figure 49). Flow-rate calculations are available in ViewArgonaut s RealTime and Processing modules. The best results are achieved with Argonaut-SW or SL systems that have a vertical beam installed. If you wish to know more about these calculations, see Appendix B Flow Rate Calculations. A description of the controls and parameters in the Flow Calculation dialog box (Figure 65) follows. - Controls Open File Opens a previously saved geometry file (*.geo). Save File Saves current Flow Calculation dialog box parameters to a geometry file. Show Preview Shows/hides the Preview window in the Flow Calculation box.

65 Figure 65. Flow Calculation Dialog Box 65

66 - Geometry (tab) Select Geometry Defines type of channel in which system is installed. The system supports four channel types: irregular open channel, trapezoidal open channel, round pipe, and elliptical pipe. o Irregular This is usually a natural streambed whose shape is defined by up to 20 survey points (X,Y or Width,Elev as used here) over the cross-section of the stream. The survey points must follow a few rules: (1) The elevation (Elev) of the first Point (i.e., Y1) must be greater than any other point, (2) Survey points must be entered in order of increasing Width (X). See Figure 65 and Figure 66 as an example. o Trapezoid Typically, this is a concrete-lined channel whose shape is defined by three parameters: Channel Depth, Top Width, and Bottom Width (Figure 67). o Round A round pipe of a given Diameter (Figure 68). o Ellipse An elliptical pipe of a given Width and Height (Figure 69). Input Dimensions This area lets you enter the dimensions for the selected geometry. o Point, Width, Elev for Irregular channels (Figure 65 and Figure 66). o Channel Depth, Top Width, Bottom Width for Trapezoid channels (Figure 67). o Diameter for Round pipes (Figure 68). o Width, Height for Elliptical pipes (Figure 69). System Elevation This parameter (Figure 65) is used in flow calculations to determine the relationship between measured water level, total channel depth, and channel area. For Irregular channels, it is the height of the top of the system relative to the same datum as the channel survey points. For Trapezoid, Round, or Ellipse channels, it is the height of the top of the system relative to the bottom of the channel. Figure 66. Flow Calculation Geometry: Irregular Figure 67. Flow Calculation Geometry: Trapezoid Figure 68. Flow Calculation Geometry: Round Figure 69. Flow Calculation Geometry: Ellipse 66

67 - Mean-Velocity Calculation (tab) Select Mean-Velocity Calculation Method This flow calculation parameter (Figure 70) is the relationship between velocity as measured by the system and mean velocity in the channel. Its options include the following settings. See Appendix B Flow Rate Calculations for details about the calculation methods. o Disabled This setting disables internal flow calculations. Flow and area data are not calculated, not output in real time, and not stored in the internal file. o Index Calibration A user-supplied index relationship is used to relate system velocity to mean velocity in the channel. This requires three index coefficients to define the relationship between measured and mean velocity. o Theoretical Flow Calculation Using the location of the system velocity cell relative to the channel geometry, a 1/6-power law relationship is used to convert measured velocity to mean channel velocity. Figure 70. Flow Calculation: Mean-Velocity Calculation 67

68 - Total Volume (tab) Select Output Units Total volume (Figure 71) is the cumulative sum of measured flow rate multiplied by elapsed time. This lets you specify the units used in the display of both flow rate and calculated volume. Six different unit combinations are allowed. o No Total Volume Output: Total volume calculations will not be made. Flow rate will be output in either cfs (English units) or m 3 /s (Metric units). o cfs & acre-ft: Flow rate output in cfs, total volume output in acre-ft. o gpm & gallons: Flow rate output in gpm (U.S. gallons per minute), total volume output in U.S. gallons. o mgd & gallons: Flow rate output in mgd (millions of U.S. gallons per day), total volume output in U.S. gallons. o m3/s & m3: Flow rate output in m 3 /s, total volume output in m 3. o l/s & liters: Flow rate output in liters per second, total volume in liters. o mld & m3: Flow rate output in mld (106 liters per day), total volume in m 3. Figure 71. Flow Calculation: Total Volume - Depth Calculation (tab) Water Depth o Pressure Offset If a pressure sensor is being used, enter any desired barometric offset value here. 68

69 Total Volume (Figure 72) This dialog will calculate the total volume of water delivered over any given portion of the file. By default, it will calculate the total volume delivered for whatever portion of the file is currently shown in the plot window. Additionally, you can manually type in a range of sample numbers to immediately update the total volume calculations for the specified range. The units used for volume calculations are specified in the Total Volume tab of the Flow Dialog (Figure 65). Sensor Calibration Settings (Figure 73) Lets you adjust any calibration settings for the various sensor types (Pressure, Temperature, External Pressure, External Sensor 1, External Sensor 2, CTD Temperature). Calibration coefficients that are adjustable include Offset, Slope, and Quadratic term. Figure 72. Flow Calculation: Total Volume Figure 73. Sensor Calibration Settings Dialog Box 69
