3 CAUTIONS AND WARNINGS Before running the InVue BT128 refractometer, heed the following: that is not affected by turbidity, diffraction and absorption of light in the sample, or a solution's acidic or electric properties. CAUTION: The InVue BT128 is a sensitive electronic device. Rough handling may cause damage. Do not drop. WARNING: The supplied USB isolator needs to be installed between the BT128 and a computer. This will eliminate potential damage to the BT128 from ground loops. HANDLE WITH CARE Touching live electrical parts can cause fatal shocks and severe burns. Incorrectly installed or improperly grounded equipment is a hazard. Do not touch live electrical parts. Properly ground the system before use. Plug the power supply into a properly wired receptacle. WORKFLOW Unpacking and hardware setup Install 128-connect software Operation User supplied tools and equipment Unpacking Installing the BT128 Connecting power Hardware device driver download Software download and installation Start up Log in to software Set up measurement file (optional) Start a measurement Cleaning sample chamber Reinitialization Follow local electrical codes and the guidelines when installing the BT128. Failure to do so may create an electrical shock hazard. Shock hazards can exist even when equipment is properly installed. The operator should be properly trained and follow established safety practices. Appendix Troubleshooting Specifications Dimensional considerations SAFE DISPOSAL When disposing of any component of the BT128 refractometer, observe the local and national requirements for the disposal of electrical and electronic equipment. UNPACKING AND HARDWARE SETUP USER-SUPPLIED TOOLS AND EQUIPMENT Supplies required for operation EQUIPMENT NOTES OVERVIEW The Entegris InVue BT128 refractometer is an optically-based, refractive index metrology solution that provides exacting and immediate results for singlesample concentration measurements of solutions in a benchtop setting. The BT128 (and the included software) enable user-friendly, real-time information and can also be utilized to determine process fluid calibration for use with the Entegris in-line monitoring devices. Utilizing the index of refraction technology (IoR) of the BT128 provides a measurement solution Computer AC power No-residue cleaning solution Lint-free wipes DI water (optional) Windows 7 or higher with.net 4.0 framework Provided AC-DC power supply requires VAC, Hz input For cleaning sample chamber. Sample dependent IPA works well for many sample types For cleaning sample chamber Used for reinitialization for refractive index reference 4

4 UNPACKING Unpack all components of the BT128 Ensure the following components are present: BT128 unit Power supply Software RS485 isolator USB cables (2) INSTALLING BT128 The sensor is a table-top module and can be installed on any flat, even surface with the required available space. CONNECTING POWER Connect the RS485 isolator and USB cables as shown below. CRITICAL: The isolator (tan box) helps prevent a ground loop to the unit. It must be connected to prevent damage to the BT128 unit. Plug power supply in to BT128 unit. Turn the unit on using switch on back of device. INSTALLING THE BT128 SOFTWARE HARDWARE DEVICE DRIVER DOWNLOAD Communication between the BT128 unit and 128-connect software is established via a RS485 to USB converted connection. IMPORTANT: Device drivers must be set up or communication issues may arise. Power on the BT128. Plug the USB cable in to the PC. Wait until Windows completes the driver installations. NOTE: If the PC does not have the appropriate drivers, Windows will attempt to download automatically from the internet. If the computer does not have internet access, the two separate drivers can be downloaded from: _Setup.zip %20Install.exe SOFTWARE DOWNLOAD AND INSTALLATION Download the software: Run the 128-connect installation program found on (go to the InVue BT128 product page where you will find a link to access the software). NOTE: Prior to downloading the software for the first time, a user profile needs to be completed and approved. Run the installer: Follow the on-screen instructions for installation of the software. The installer program outputs an icon for InVue BT128 Connect on the desktop and creates a default data storage location on your computer s hard drive. 5

5 UNIT OPERATION START UP If not on already, power on the BT128. Start the BT128 software by clicking on the InVue BT128 Connect icon. Use one of the following passwords: Operator mode: testop Allows for data logging and measurement. Supervisor mode: testsuper Adds the ability to recalibrate and reinitialize the sensor. SET UP MEASUREMENT FILE (OPTIONAL) Users can set up a.csv measurement file to log measurement results. To set up a measurement file: Click the MENU button. Select CREATE MEASUREMENT FILE from the list. The software will now perform a 15 minute warmup period of the BT128. In the resulting file dialog pop-up, navigate to a preferred file location and name the file. To view the folder location of the measurement file: Click the MENU button. Select OPEN MEASUREMENT FILE FOLDER from the list. START A MEASUREMENT LOG IN TO SOFTWARE The software is password protected for various levels of users. Log in to the software by clicking the LOGIN button. After logging, the BT128 is ready for sample measurements. Inject sample to be measured: Open the sample chamber lid. Sample volume is 1 to 2.5 ml. IMPORTANT: Ensure sample covers the entire optical window. Close the sample chamber lid. 6

6 Start Measurement REINITIALIZING (ADVANCED) Occasionally, the unit may need to be reinitialized to correct for any errors. Click the START MEASUREMENT button in the software. Assign a Sample ID Enter the name of the sample to be measured. NOTE: DI H 2 0 will be needed during this procedure as a Refractive Index reference. Prepare for reinitialization: Clean and dry the sample chamber. IMPORTANT: Ensure the optical window in the sample chamber is clean and free of any debris or watermarks. BT128 Reinitialization Wizard: Log in as Supervisor (see Log in to Software section). Click the MENU button. Select REINITIALIZE SENSOR from the list. The BT128 will now proceed with the measurement and display the results upon completion. Follow the on-screen wizard to complete reinitialization process. CLEANING SAMPLE CHAMBER Once measurement is complete, the sample chamber will need to be cleaned. Cleaning sample chamber: Using appropriate safety precautions, clear the sample from the sample chamber using a lint-free wipe. Clean the sample chamber using a lint-free wipe and a zero-residue cleaning solution. IMPORTANT: Ensure the optical window in the sample chamber is clean and free of any debris or watermarks. 7
