Calibrate a conductivity sensor
Improve the accuracy of a conductivity sensor, such as the Wireless Conductivity Sensor (PS-3210A), via calibration.
Before you start
Calibrating a conductivity sensor will require the following supplies:
- Two beakers
- Two standard solutions of known conductivity
- De-ionized water
Calibration
- Connect your conductivity sensor to Capstone.
- Select Calibration from the Tools palette.
- Select Conductivity from the dropdown box, then click Next.
-
Ensure that Two Standards (2 point) is selected from the list of calibration types, then click Next.
-
Insert the conductivity sensor's probe into a beaker containing your first standard solution, making sure the sensing element is immersed. Wait for the value of conductivity recorded in the Current Value box to stabilize.
- Enter the known conductivity of the first standard solution into the Standard Value box, then click Set Current Value to Standard Value.
- Remove the sensor from the first beaker and rinse the probe with de-ionized water.
- Insert the probe into a beaker containing the second standard solution, making sure the sensing element is immersed. Wait for the value of conductivity recorded in the Current Value box to stabilize.
-
Enter the known conductivity of the second standard solution into the Standard Value box, then click Set Current Value to Standard Value.
-
Review your new calibration to ensure it is appropriate, then click Finish.
