Sensor Control 2 Software (LabView Version) Installation and Use Instructions

Form: ??????-Rev A [Rev: 2020-07-07] © 2020 Sensorex Corporation

Download Files and Load InterfaceNote that your computer must be connected to the Internet during the software installation process, as it must have access to the latest LabView drivers. These instructions only apply to the Microsoft Windows OS.

1. See link for files:

2. Unzip files.

3. Load: Smart_Sensor_User_Interface_D installer. Files will write to C:\Program Files(x86)\Smart_Sensor_User_Interface\D.

4. Load: Smart_Sensor_User_Interface_D.

Sensor Connection

Options for Connecting Sensor to Computer USB Port:

1. Sensorex CALBOX-MB

Uses the power from your computer so you will simply match wire colors from sensor cable to CALBOX-MB terminals with corresponding color names.

2. Modbus485 to USB Converter

You will also need to connect the sensor to 12VDC power using this connection type. Wiring is as follows:

Red = 12VDC +Black = GNDWhiteWhite = Modbus AGreen = Modbus B

Smart Sensor Interface

Getting Started

1. Open the Sensorex Smart Sensor Interface. The screen will appear as shown in Figure 1.

3. Click Low Cal Point button.

4. A message will flash in the Cal Message window: When reading is stable, click off the Low Cal Point button.

5. Click off the Low Cal Point button.

6. The Cal Message window will say it is averaging the reading before displaying: Low Point Calibration Finished.

7. Rinse electrode in deionized or distilled water.

8. Place electrode in High Calibration buffer (pH 7.00 or pH 10 are most common).

9. Repeat Steps 4 -6.

10. The Cal Message window will show: High Point Calibration finished. Click Save button to save the calibration data into the sensor memory. Click the Save button.

11. The Cal Message window will show: Saving Calibration Data into Sensor Memory.

12. The next message will show: Calibration data saved and Read back the calibration log.

13. The saved data will then be entered into the table on the bottom of the screen in the Recent Calibration Data section’s top position, Latest Time. Note that the software will only save the last three calibration data sets.

Calibrate Contacting and Toroidal Conductivity Sensors

1. Place sensor in air to calibrate low calibration buffer reading (0us).

2. Enter the value of the low buffer into the window.

3. Click the Low Cal Point button.

4. The following message will flash in the Cal Message window: When reading is stable, click off the Low Cal Point button.


6. The Cal Message window will say it is averaging the reading, then: Low Point Calibration Finished.

7. Rinse electrode in deionized or distilled water.

8. Place electrode in High Calibration solution.

7



9. Repeat Steps 4-6 above.


11. The Cal Message window will display: Saving Calibration Data into Sensor memory.

12. The next message will say: Calibration data saved and Read back the calibration log.

13. The saved data will then be entered into the table on the bottom of the Recent Calibration Data screen in the top position labeled Latest Time. Note that the software will only save the last 3 calibration data sets.

Calibrate Dissolved Oxygen (DO) Sensors

1. Place sensor in Zero Solution to calibrate low calibration buffer reading (

8



Calibrate Free Chlorine Sensors

1. Place sensor in air to calibrate low calibration buffer reading (0 ppm).

2. Enter the value of the low buffer into the window (0 ppm).

3. Click the Low Cal Point button.

4. The following message will flash in the Cal Message window: When reading is stable, click off the Low Cal Point button.


6. The Cal Message window will say it is averaging the reading, then Low Point Calibration Finished.

7. Rinse the sensor in deionized or distilled water. Dry off.

8. Pour calibration solution 20ppm into a beaker or cup. Insert sensor for high point calibration value.

9. Repeat Steps 4 -6 above.


11. The Cal Message window will display: Saving Calibration Data into Sensor memory.

12. The next messages will display: Calibration data saved and Read back the calibration log.

13. The saved data will then be entered into the table on the bottom of the Recent Calibration Data screen in the top position labeled Latest Time. Note that the software will only save the last three calibration data sets.

4. If the screen shows the previous default setup values, then the right COM port has been selected. Otherwise, select a different COM port and repeat Step 3.

5. You can choose to add a label to your sensor (maximum 12 characters) for identification. Move the cursor into the user label slot, click it, and type in the desired label. Then click on the Write button. The Read User Label space will show your label.

Calibration

1. To calibrate the sensor, you will need two standard calibration solutions corresponding to the measurement. Follow the onscreen messages in the Cal Message box to conduct the calibration.

2. After the two-point calibration is complete, click the Save Calibration button. The previous three calibration values and time (YYYYMMDDHHMM format) will be updated with the newest calibration values.

3. To conduct the temperature calibration, enter the reference standard value in Celsius. Click Write Temperature for the sensor to accept the temperature calibration value.

Measurement and Log

1. Click the Start/Stop Measurement button to display the measurement.

2. Select Plot Display Selection for the chart to display in one of the three parameters.

3. Create the folder on the computer before logging. Move the cursor into the file name slot and enter the file name.

4. When the measurement is running, click the Start/Stop Record button to start logging data.

5. The default value is one second/sample. This may be changed as needed.
