6 MultiCorr MKII - User Manual Page: 6 1 INTRODUCTION The MultiCorr MKII is a software based, computerized, hand held corrosion meter and data acquisition unit suitable for the interrogation of different types of corrosion probes. It is housed in a rugged rubber coated housing that is splash resistant and intrinsically safe. Each MultiCorr MKII can be individually configured to the user's specific needs at the time of purchase. Additionally, the unit can have its software upgraded at any time to add Functions which were not included at the time the unit was purchased. Each MultiCorr MKII has the capacity to store up to 3,000 sets of readings. Readings may be stored in memory along with a unique probe number, an alphanumerical tag designation, along with an automatically generated reading date and time. Written records are not required, but can be easily maintained. 1.1 Capability and Functions The MultiCorr MKII is capable of monitoring a wide variety of corrosion probes, so there is no need to purchase or use different corrosion monitoring instruments when measuring different types of corrosion probes. Shown below is a summary of the Functions available in the MultiCorr MKII Instrument. Function Capability ER Probe Read and Monitor Electrical Resistance Probes LPR Probe Read and Monitor Linear Polarization Probes Galvanic Probe Read and Monitor Galvanic Probes Analog Probe Read and Monitor Reference Electrodes, Monitored Anodes, Temperature and Pressure Sensors Polarization Conduct several types of polarization measurements. Potentiostatic, potentiodynamic and cyclic polarization may be performed. Automatic Conduct Automatic Readings at Uniform Time Intervals Terminal Function for MultiLog Setup of MultiLog Stations, data transfer from MultiLog to the MultiCorr MKII, data transfer from the MultiCorr MKII to PC, etc. Terminal Function for SandLog Setup of Sandlog Stations, data transfer from SandLog to the MultiCorr MKII, data transfer from the MultiCorr MKII to PC, etc. The user can include all of the above Functions in a single instrument or chose any possible combination of Functions at the time of purchase. For instance, you may configure an instrument to read only ER Probes and take automatic readings or have an instrument that can read ER, LPR and Galvanic Probes, take Automatic readings and perform Polarization measurements. The MultiCorr MKII can grow with your operations since any Function which was not included when the unit was delivered may be added at a later date.

7 MultiCorr MKII - User Manual Page: Probe Compatibility The MultiCorr MKII is a versatile instrument which accepts corrosion probes of different designs and from different manufacturers. There are default settings within the MultiCorr MKII for each type of probe, and the user can easily modify these settings so that any probe can be read regardless of the manufacturer. Because of variations in the size and type of connectors it may be necessary to have different cables for different manufacturers. When ordering, please specify the manufacturer and probe type and CorrOcean will provide the required probe cables to suit the user's needs. 1.3 Data Transmission To PC The MultiCorr MKII can communicate directly with any IBM compatible Personal Computer (PC), which has been loaded with the CorrOcean Corrlist Software provided with the MultiCorr MKII. It can also communicate directly with other CorrOcean Software programs such as CorrTrend and CorrChart. CorrTrend is an advanced corrosion data management program and CorrChart can be utilized to automatically plot and present polarization curves. Data transfer to the PC can be performed using either direct data transfer cables or via a modem. When used as a terminal, the data are transferred into the CorrOcean software MultiCom or SandRater (for MultiLog and SandLog data respectively) 1.4 Manual Use and Information This manual includes information on the use of every feature of the MultiCorr MKII Instrument. The manual provides details on the use of functions which may not have been included in the MultiCorr MKII purchased by the user. Any MultiCorr MKII function may be added to your instrument after it has been purchased. Call the nearest CorrOcean office listed in the back of this manual for more information on how to upgrade your MultiCorr MKII. It is recommended that the MultiCorr MKII Instrument be used while reading this manual so that the various options may be tried as the user is reading the manual.

9 MultiCorr MKII - User Manual Page: 9 3 HANDLING AND STORAGE 3.1 General The MultiCorr MKII is built into a rugged splash proof case and is designed for operation in an offshore, industrial and/or hazardous environment. Carefully selected materials have been used to meet these requirements. For example, the application of a silicone rubber cover on the bottom part provides thermal insulation, shock absorption and a friction mantle. The silicone rubber can withstand environmental temperatures up to 550 F (300 C). However, the user must remember this is an electronic instrument and if it is left on a hot surface and the internal temperature is allowed to exceed 160 F (70 C), the instrument may be permanently damaged. The specifications on the MultiCorr MKII are described in APPENDIX A "MultiCorr MKII Specifications". 3.2 Packing The instrument comes complete with a battery charger, PC data transmission cable, Corrlist software and a users manual. All of the components are packed in a plastic transportation case filled with shock absorbing foam. The plastic case is meant for shipment and storage only, and is not intended for use in a hazardous area. 3.3 Initial Inspection The instrument was carefully inspected both mechanically and electronically prior to shipment. It should be free of physical damage upon receipt. To confirm this, the instrument should be inspected for any damage that may have occurred during shipment. If any damage is observed please contact CorrOcean immediately. 3.4 Storage The instrument may be stored or shipped in environments within the following limits: Temperature: -5 F to 160 F (-20 C to 70 C) Humidity: Up to 95% The instrument must be protected from extreme temperatures which may cause condensation to form within the instrument case. It is recommended that the instrument is stored in a dry, cool place (not colder than -5 F (-20 C)) to minimize battery discharge. To prevent loss of stored data and keep the internal clock running, recharging should be carried out at least once every 3 months. This recharging should be more often if the unit is stored at temperatures beyond 85 F (30 C) or if the battery is old.

10 MultiCorr MKII - User Manual Page: Charging Charging time for empty batteries is approximately 12 hours. The instrument may also be operated during charging. Charging should only take place in nonhazardous areas. LOW BATT is displayed on the instrument's status line when the battery charge drops below a certain limit. The batteries should be recharged as soon as possible after this. If operation continues, the power will automatically be switched off when the voltage drops below the secure operation limit. The automatic switch off function is to insure that there is sufficient battery charge to save stored data. If the instrument has automatically switched itself off under these conditions, it will not be possible to make measurements until it has been recharged. NiCd batteries can occasionally develop a "memory" which limits the available user time. If this occurs deplete the battery through use and then recharge. This process of draining the battery and recharging may have to be repeated. 3.6 NiCd Batteries The MultiCorr MKII NiCd batteries have a design life of 3 to 5 years depending on the use and care. The battery package was made especially for the MultiCorr MKII instrument and are designed not only for a specific power usage but also for use in a hazardous environment. Changing the battery should only be conducted by personnel authorized by CorrOcean, to insure that the hazardous area requirements are maintained. Warning: NiCd batteries slowly loose their charge even when not in use. For this reason it is important to charge the batteries at least every 3 months, even if the MultiCorr MKII is not being utilized. If the NiCd batteries are not recharged when the LOW BATT Warning appears it is possible that stored data may be lost if the battery charge level drains below the minimum level necessary to maintain the MultiCorr MKII memory. The battery voltage can be seen by selecting STATUS in the system or acq. setup menues. Both the positive and the negative battery should be at more than 6.25 V when they are charged. The voltages are however depending on the temperature. 3.7 Connecting to a Personal Computer The battery charging cable also contains a cable branch for connecting it to a PC RS-232 port. The MultiCorr MKII may be connected to a PC for data transfer whether or not the battery charger is connected to an outlet. It is recommended that the charger be connected when data transmission is being accomplished, but this is not required. The standard connector on the PC Data Cable is a 25 pin, female connector. Some computer ports may require the use of a 9 pin female connector, in which case an adapter may be utilized. Connection to a PC should only take place in nonhazardous areas.

11 MultiCorr MKII - User Manual Page: Connecting to a Probe The MultiCorr MKII is connected to the probe using a flexible retractable probe cable. The probe cable and connector assembly will be different for the different probe types, and may also be different for probes from different manufacturers. Probe cables can be supplied by CorrOcean according to user's specifications. For most commercial corrosion probes, probe cables can be supplied on short notice. Please contact CorrOcean for more information. The probe cable has an 11 pin male Fisher connector on the instrument side. There is a white orientation dot on the Fisher connector that should be visible on the top of the connector when inserting the cable into the MultiCorr MKII. Always insert and remove the cable by grasping the connector housing and never pull directly on the cable itself. The internal wiring of probe cables may be different even when the connector appears to fit the probe. Make sure that both the probe and cable are compatible for both probe type (e.g. ER, LPR) and manufacturer. NOTE: The instrument housing is electrically conductive. When measuring on LPR and galvanic probes, the instrument must be held in the hand, or otherwise electrically isolated from ground.

12 MultiCorr MKII - User Manual Page: 12 4 MULTICORR MKII INSTRUMENT 4.1 General The user interface of MultiCorr MKII is implemented with an efficient and easy to learn on screen menu system. In this manual the definition of a menu is a list of functions which can be selected with a single numerical key entry. Throughout this manual the keyboard entries are enclosed in brackets [ ] to distinguish them from other numerical listings. The definition of a window is a display screen with specified contents. Probe information may also be edited or new information may be added utilizing CorrOcean's CorrTag Software which is described later in this manual. Since the MultiCorr MKII can store hundreds of different probes in its memory the operator will learn how to select a specific probe so that readings are calculated and stored for that specific probe. In this manual the probe which is ready to accept and store readings at any given time is referred to as the Active Probe. 4.2 Entry Keys The key board on the MultiCorr MKII is generally self descriptive but it is helpful to understand the use of these keys as they are used the MultiCorr MKII. Key Use Description [On/Off] On or Off Use to turn the MultiCorr MKII screen on or off. The MultiCorr MKII has an internal battery saver which will turn off the instrument if no key is pressed within 2 minutes of the last key entry. [Del] Delete This key is used to delete the last erroneous character entered. You may also use the left arrow key to make a deletion. [Exit] Exit The [Exit] key is used to leave a menu or a window. Terminating data entry with the [Exit] key leaves the previous value unchanged. [Ent] Enter When entering parameters such as probe numbers or the surface area of an LPR Probe electrode, the input must be terminated with the [Ent] key. The input value will not be accepted until the entered value is within legal limits. When an illegal entry is made, the display cursor will return to the first position in the input field and a new value may be entered.

13 MultiCorr MKII - User Manual Page: 13 Arrows Up/Down Once probe parameters have been entered into the unit the operator can display the next probe in sequence by pressing the down arrow or returning to a prior probe with the up arrow. When the menu is set to display data the operator can move through the reading summary using the Up and Down arrows. These arrows are also utilized when selecting the alphanumeric tag numbers. This use is described more fully later in the manual. Arrows Left/Right The left arrow may be used to delete an erroneous character entry. These arrows are also utilized when selecting the alphanumeric tag numbers. This use is described more fully later in the manual. 4.3 Data Screen The MultiCorr MKII uses a Liquid Crystal Display (LCD) screen. As a battery saving feature the screen will automatically go blank if no key has been pressed during any two (2) minute interval. The screen will also go blank during the periods between automatic readings. The LCD display utilizes a standard pattern for the display of information. Line Location First Line selection. Description Provides the name of the menu. This corresponds to the previous Second Line This is a warning information line. When the battery is low a "LOW BATT" warning will appear. When the instrument is set to automatically take readings an "AUTO-ON" Warning will appear. Additionally, if the MultiCorr MKII memory is full a "MEMORY FULL" Warning is displayed. Lines 3-8 Menu selection alternatives are listed when a menu is displayed. When the unit is in an operational mode, the last two lines (7-8) display the Active Probe in memory. Both the probe number and tag number are displayed. Line 3-8 is also used to display any electrical measuring errors which may be detected by the MultiCorr MKII. The meaning of these error messages is provided in APPENDIX G - MultiCorr MKII Error messages.

14 MultiCorr MKII - User Manual Page: Probe Identification System - Probes Measured by MultiCorr MKII The MultiCorr MKII uses a standard method to identify each probe so that the user can readily identify the probe which is being interrogated. It is important for the user to understand this identification system prior to reading the manual. The following identification labels have a specific meaning that is described below. Probe No Each probe is assigned a unique number that includes both the type of Probe (e.g. ER, LPR, Galvanic) and a number from 0 to 99. For instance ER 23, LPR 99 or Glv 0. All ER Probe Numbers will start with "ER" and all LPR Probe Numbers will start with "LPR". The MultiCorr MKII will distinguish between probes of the same type by the number following the probe type designation. A total number of 200 different probes may be defined. Probe Numbers must be assigned before the MultiCorr MKII will take a reading. Tag No The Tag Number allows the user to assign a name to each probe that can assist in identifying the probe. The Tag Number may be up to 10 alphanumeric characters in length. For instance, the user could tag probe ER 12 with the additional identification of "Riser A67". When this probe is selected the MultiCorr MKII screen would display the following as the Active Probe. Probe: ER 12 Tag No: Riser A67 Tag Numbers are not required to be entered before the MultiCorr MKII takes a reading. However, it is recommended that Tag Numbers are assigned. 4.5 Probe Identification System - Probes measured by MultiLog The probes measured by MultiLog are identified by tag no. etc. as defined in the MultiCom software (it is referred to document for description of the probe identification system). However, to reduce complexity and data amount to be transferred, tag numbers etc. are not given in the probe identification in the MultiLog stations and Terminal. Identification of the probes are given by MultiLog station no, probe type and number. Probe number starts at 1 for each probe type for each logger. When MultiLog data are stored in the MultiCorr MKII memory, "tag number" will be automatically generated. This number is used only for display of probe data and is not transmitted when data are sent to PC. However, these tag numbers will be part of the total capacity of 200 tag numbers, and are cleared by reset of the MultiCorr MKII only (please see section 11.3 for reset instructions).

15 MultiCorr MKII - User Manual Page: Probe Identification System - Probes Measured by SandLog The probes measured by SandLog are identified by the SandLog address and probe number. A SandLog is measuring one or two sand probes. A sand probe may have 2, 3 or 4 measuring elements, and each element is displayed individually. SandLog address and probe number must be defined before measurements are initiated, please see section for logger setup. Also see figure 32 for data display in SandLog. The corresponding sand probe identification is found when data is transferred to the MultiCorr MKII. Section describes display of the stored data, an example is shown in figure 37. For complete sand monitoring system setup, it is referred to "SandRater Sand Monitoring Program Operating Manual".

16 MultiCorr MKII - User Manual Page: 16 5 MENU DESCRIPTION 5.1 The Main Menu The MultiCorr MKII Main Menu is displayed when the meter is turned on. This menu allows the user to select two operating modes which are defined as the "Operator Mode" and the "Advanced Mode". Operator Mode This is a limited use mode designed to allow only field measurements and storage. This limited operational mode permits the user to quickly take readings without the need to utilize the expanded menu selection. Advanced Mode This menu mode allows the corrosion specialist to set probe parameters, take automatic readings, set engineering units, transmit data to a PC and perform a wide variety of specialized operations. Some areas of this menu are protected by a pass code to insure that inadvertent changes are not made to the system. Field measurements may also be taken using the mode. Terminal Mode This menu mode allows setup of CorrOcean MultiLog and/or SandLog stations, check of data and data retrieval from MultiLog/SandLog and data transfer to relevant PC software. Some areas of this menu are protected by a pass code to insure that inadvertent changes are not made to the system. Shown in Figure 1 is the Main Menu of the MultiCorr MKII. To enter either the Operator Mode or the Advanced Mode the user simply presses the corresponding selection number located in front of the desired selection. The MultiCorr MKII will immediately move to the first menu level for that operating mode. Figure 1 shows the menu with five (5) types of probe functions and terminal function installed. Only the functions which are actually installed in the user's MultiCorr MKII will be displayed. *** MultiCorr MKII *** Probes: ER - LPR Glv - Ana Pol 1: Operator Mode 2: Advanced Mode 3: Terminal Mode Figure 1

17 MultiCorr MKII - User Manual Page: Operator Mode There are only 2 possible selections in this mode. The user can either decide to take a measurement on the Active Probe or change the Active Probe prior to making a measurement. The details on how to install probe information, take measurements and store the results are provided later in this manual. Shown in Figure 2 is the Operator Mode Main Menu Window. Details on making measurements are provided in Section 8.0. * MEASURE * 1: Measure 2: Select Probe Probe = ER 12 Tag No: Riser A67 Figure Advanced Mode The Advanced Mode allows the user to make measurements in the same manner as the Operator Mode and also allows the use of the advanced capabilities in the MultiCorr MKII. The most sensitive functions in the Advanced Mode are protected with a pass code to prevent data loss or corruption caused by unauthorized operators. Shown in Figure 3 is the Advanced Mode Main Menu Window. There are six (6) general capabilities that can be accessed through the use of the Advanced Mode. The use of these capabilities are described in more detail later in this manual. For now it is only important to understand the general capabilities of the MultiCorr MKII and how these are arranged in the menu structure. 1: Acq. Setup 2: Measure 3: Show Data 4: System 5: Transmit 6: Automatic Figure 3 * MAIN MENU * 1. Acquisition Setup This menu route allows the user to enter the various parameters for each type of probe, enter the tag identification and establish data reading variables such as the type of engineering units. 2. Measure The user can take field measurements exactly the same way as it is accomplished in the Operator Mode. 3. Show Data The user can view all the stored readings for any probe including raw data, calculated results and corrosion rates. 4. System Setup This menu route allows the user to set the date and time, clear the memory of readings, clear the unit of probe parameters, change the pass code and also check the remaining memory. 5. Transmit This feature allows the stored data to be transferred to a computer.

18 MultiCorr MKII - User Manual Page: Automatic THIS IS AN OPTIONAL FUNCTION THAT MAY NOT APPEAR ON ALL UNITS. It allows the user to automatically take and store readings at regular intervals. This function may be added to any MultiCorr MKII. 5.4 Terminal mode The choice of terminal mode allows user to use the MultiCorr MKII as a terminal for MultiLog and/or SandLog stations (depending on which functions installed). If both terminal functions are installed the choice of terminal mode will bring you into a submenu where you can choose between SandLog and MultiLog terminal. When used as a Sand Terminal you cannot operate MultiLog stations and vice versa. If only one terminal function is installed the above mentioned submenu is skipped, and you are brought directly into the installed terminal menu. 5.5 Menu Paths As menu selections are made, the MultiCorr MKII will move to the next appropriate menu. This means that if the MultiCorr MKII needs additional information (For instance, probe parameters) it will automatically move to the appropriate menu. When the unit has the necessary information to proceed with an entry it will skip unnecessary menus. This feature saves the user time and minimizes confusion. There are some general rules which will assist your understanding of this manual and which are applicable to all menus. 1. Throughout this manual the keyboard entries are enclosed in brackets [ ] to distinguish them from other numerical information listings. 2. The Enter Key [Ent] is used to confirm your entry and to move to the next screen. 3. The Exit Key [Exit] is used to leave the entries unchanged and moves you forward in the menu path.

19 MultiCorr MKII - User Manual Page: 19 6 PROBE IDENTIFICATION AND METER SETUP There are general procedures that apply to all probes and these procedures are discussed in this section. Additionally, the user will learn how to check the operational status of the MultiCorr MKII and select the type of engineering units which are to be used for the probe readings. The intent of this section of the manual is only to familiarize the user with general procedures for identifying and labeling all types of probes. Section 7 takes the operator on a step by step procedure for entering the parameters for each specific type of probe. Before taking any measurements the user must assign a unique number to each probe. This number will define the type of probe (For instance ER or LPR) and allow the MultiCorr MKII to know where the readings will be stored. At the same time that probe number is assigned you may also assign a location name, called a Tag Number, to assist you in recognizing the probe you are measuring. Note that if a Tag Number is not assigned, it is possible to enter the Operator Mode and change the probe parameters without entering the Pass Code. To protect the probe parameter setup, a Tag Number must be assigned for the probe. All of the steps necessary to complete each operation are given along with the keys that need to be pressed and the results that will be obtained. 6.1 Selecting Probe Type and Assigning a Probe Number This procedure allows the user to assign a Probe Number without also assigning an identifying Tag Number. 1 [On/Off] Turn on MultiCorr MKII 2 [2] Go to Advanced Mode 3 [1] Go to Acquisition Set Up 4 [1] To Edit Probe 5 [Pass Code number] Enter your personal passcode 6 [Ent] Enter pass code and move to next menu 7 [1] To select a Probe Type 8 [1] through [5] Select the type of probe which will be assigned a number NOTE: Since every MultiCorr MKII is configured for each user, the meter you are using may not have 5 options from which to select. For your general information the five (5) possible key selections and the respective probe functions are as follows: [1] ER [4] Analog [2] LPR [5] Polarization types [3] Galvanic In addition, the two teminal modes, MultiLog and SandLog, are available functions.

20 MultiCorr MKII - User Manual Page: 20 9 [Ent] To move to Next Menu Screen 10 Enter Any No The user can assign any number from 0 through 99. The numbers do not have to be consecutive. It is often helpful to assign the numbers in the same sequence that the operator encounters the probes while taking field readings. HINT: If additional probes will be added to the reading circuit, skip some numbers so consecutive number spaces will be available at a future date. 11 [Ent] Enters the number you selected. From this point on the entries depend on the type of probe being utilized. Section 7 of this manual provides details on how to enter the parameters for each type of probe. The same steps as shown above will be repeated, but the background information will be excluded. 6.2 Installing and Editing Probe Tag Identification The MultiCorr MKII provides two (2) Methods for installing Tag Numbers and probe parameters. 1. Manual installation through the use of key entries on the MultiCorr MKII. 2. Automated downloading of probe files through the use of CorrTag Software Manual Probe and Tag Number Entry Using The MultiCorr MKII This procedure allows the user to assign a Probe Number and also assign an identifying Tag Number. Generally, this is a preferred manual procedure to just assigning a probe number as shown above in Section 6.1. However, to assign a Tag Number using the MultiCorr MKII the user must know the pass code assigned to that particular MultiCorr MKII. 1 [On/Off] Turn on MultiCorr MKII 2 [2] Go to Advanced Mode 3 [1] Go to Acquisition Set Up 4 [1] Edit probe 5 [Pass Code Number] Enter your personal passcode 6 [Ent] To Enter Pass Code and move to the next Menu 7 [1] To Select Probe 8 [1] through [5] Select the type of probe which will be assigned a number 9 [Ent] Enter the probe type you selected 10 Enter Any No The user can assign any number from 0 through 99. The numbers do not have to be consecutive. It is often helpful to assign the numbers in the same sequence that the operator encounters the probes while taking field readings. HINT: If additional probes will be added to the reading circuit, skip some numbers so consecutive number spaces will be available at a future date. 11 [Ent] Enters the number you selected. NOTE: As explained in Section 6.1 above, at this point the available functions in each MultiCorr MKII will vary. 12 [2] Edit Tag no.

21 MultiCorr MKII - User Manual Page: 21 Figure 4 shows the Edit Tag Number window through which an identifying Tag Number may be assigned. Tag Numbers may be up to 10 characters long. To keep the meter as simple as possible, the MultiCorr MKII does not have an alphanumeric keyboard. The alphabet is displayed on the bottom of the screen. Characters are entered by the use of the arrow keys and then selected using the Enter Key [Ent]. 1. Move the Cursor to the desired character using the Arrow Keys and select it by pressing the Enter Key [Ent]. 2. Numbers are selected directly by pressing the Number Keys on the MultiCorr MKII Keyboard. ---EDIT TAG NO-- PROBE = ER 12 { } ABCDEFGHIJKLMNO PQRSTUVWXYZ /( ) + &#$ * <accept> Figure 4 3. Note that you may select an open space in the Tag Number by placing the cursor under the open space (after Z on the screen) and pressing [Ent]. An open space counts as 1 of the maximum 10 allowable characters. 4. To delete an erroneous entry press the Delete Key [Del]. To accept the completed Tag Number move the cursor to [accept] and press the Enter Key [Ent]. From this point on the entries depend on the type of probe being utilized. Section 7 of this manual provides details on how to enter the parameters for each type of probe. The same steps as shown above will be repeated.

22 MultiCorr MKII - User Manual Page: Probe Information Installation Using CorrTag Software CorrOcean has developed a PC software package called CorrTag which allows the MultiCorr MKII user to enter all of the Probe Numbers, Tag Numbers and Probe Parameters in a computer file and then download this information directly into the MultiCorr MKII Meter. When using CorrTag the user can create files containing the probe information for different locations. This allows the user to simply clear all of the existing probe information from the meter and download just the file containing information needed for the geographic area where probe readings will be taken. Some illustrative examples of how CorrTag may be used are as follows: 1. If a plant has more than 200 probes of a given type, simply divide the plant into areas of less than 200 probes and create a separate file for each area. 2. If there are distinct geographical areas where probes are to be measured the user can create a separate file of the probe parameters for each area. Before visiting a location the user can clear the meter, download the probe information and quickly proceed with taking measurements without having to reenter probe information. This also removes the possibility that readings could be mistakenly entered into a probe that is not located in that area. Details on the use of CorrTag are provided in the CorrTag Data Sheets and user manual. The steps necessary to set up the MultiCorr MKII to receive CorrTag files are as follows: 1 [On/Off] Turn on MultiCorr MKII 2 [2] Go to Advanced Mode 3 [1] Go to Acquisition Set Up 4 [2] Load from PC 5 [Pass Code Number] Enter your personal passcode 6 [Ent] To Enter Pass Code and move to the next Menu The MultiCorr MKII is now set to receive any desired CorrTag file. The actual initiation on the data downloading is started from the PC software menu. If your MultiCorr MKII does not provide for a selection between "Manual" and "Using PC" then the internal electronics will need to be upgraded before you may use CorrTag Software. NOTE: If the MultiCorr MKII is not reset to eliminate all of the existing Probe Numbers and parameters the CorrTag files will override any existing Probe Numbers that are the same as in the downloaded file. Resetting the MultiCorr MKII is detailed in Section Reading Setup The MultiCorr MKII allows the user to define both the number of samples taken with each reading and the engineering units for the measurement of ER and LPR Probes.

23 MultiCorr MKII - User Manual Page: Number of Samples per Reading Normally a user would make a probe reading and obtain a display of the result for that reading. However in some cases, especially when the system to be measured is not stable, it may be advantageous to have a single reading represent the average of multiple samples. The MultiCorr MKII allows the user to establish the number of samples that can be averaged to obtain a single displayed reading. The actual raw data samples that make up the single reading may also be viewed by the operator so that the actual measured stability may be reviewed. The procedure for displaying raw data is discussed in Section 10.0, Displaying Measurement Data. The default value set in the MultiCorr MKII is 1 sample for each reading. The user can set the MultiCorr MKII to take up to 50 samples each time a measurement is made. Regardless of the number of samples which is defined only a single average result will be displayed. Setting the number of samples to a number above 1 will enhance the stability of the readings, but it will also increase the time required to perform a measurement. Increasing the number of samples per reading will also increase battery consumption and the total number of readings which may be obtained on a single charge will be reduced. Unless there is a specific reason to suspect a stability problem using the default value of 1 sample per reading is probably adequate. The additional sample readings are only made on the actual reading element step so increasing the number of samples, to say 3, does not require three times as much time as a single sample size. The user may want to test out some multiple sample sizes to optimize the stability of the readings and the time it takes to obtain measurement results. To set the number of samples follow the steps shown below: 1 [On/Off] Turn on MultiCorr MKII 2 [2] Go to Advanced Mode 3 [1] Go to Acquisition Set Up Menu 4 [3] Go to Reading Set Up Menu 5 [Pass Code Number] Enter your personal passcode 6 [Ent] To enter pass code and move to next menu 7 [1] Select No of Samples 8 Enter [1] through [50] Defines number of samples per reading 9 [Ent] Enters sample number and returns to Reading Set Up Menu 10 [Exit] Returns to Acquisition Set Up Menu

24 MultiCorr MKII - User Manual Page: Selection of Engineering Units The MultiCorr MKII allows the user to set their preferred engineering units. There are two (2) types of units for each type of probe. To select the engineering units follow the steps shown below: 1 [On/Off] Turn on MultiCorr MKII 2 [2] Go to Advanced Mode 3 [1] Go to Acquisition Set Up Menu 4 [3] Go to Reading Set Up Menu 5 [Pass Code Number] Enter your personal passcode 6 [Ent] To enter pass code and move to next menu 7 [2] Go to Engineering Unit Menu 8 Enter [1] through [2] Defines the units for every Type of Probe based upon which entry [1] through [2] is pressed.

For instance, if you select Key [2] (Mils) for an ER probe then the LPR probes will read in mpy and the ER probes in mils/mpy. Listed below is a summary of the units that will be established when making an engineering units selection. The user may also change the engineering units after the data has been transferred to a Corrlist file.

25 MultiCorr MKII - User Manual Page: 25 7 DEFINING PROBE CHARACTERISTICS AND PARAMETERS 7.1 General The concept for the operation of the MultiCorr MKII is that the meter shall be capable of handling different Probe Types and different Probe Manufacturers. In order to accomplish this versatility, the user enters the probe parameters for each individual Probe. The MultiCorr MKII provides an easy and logical selection menu approach to assist the user in entering probe parameters. Probe parameters can be entered from either the Operator Mode or the Advanced Mode which were discussed in Section 5 of this manual. However, identification Tag Numbers can only be installed from the Advanced Mode so all of the examples will use the Advanced Mode menu. The probe parameters should be installed by the system or corrosion engineer. Tag information is protected by a pass code in the meter to avoid tampering or accidental changes by a field technician. A pass code number is supplied with the MultiCorr MKII at the time of delivery but it may be changed by the operator using the Advanced Mode and the existing Pass Code. Once a Tag Number has been defined for a Probe, the probe parametes are protected by the Pass Code. In MultiCorr MKII, raw data, such as resistance for ER Probes and current and voltage for LPR and galvanic Probes, is stored. Thus, when changing probe parameters, the displayed measurement values will change for all measurements for that Probe stored in the instrument. However, the raw data will remain unchanged. Additional Technical Information on each type of probe is provided in the Appendices of this manual. The Appendices also provide details on the formulas used to calculate displayed values and how corrosion rates are calculated.
