Description
In the OmegaMeter, the resistivity is measured by use of a sensor that comes in contact with the test solution and by circuits that take the sensor's measurement and convert it to a reading on the LCD screen.
Here are the steps to replace a sensor
- Make sure the test cell is drained of fluid
- Unplug the OmegaMeter from AC power
- Unplug the Resistivity sensor electrical connection
- You will have to unscrew the connector housing
- Then separate the connector
- Carefully remove the Resistiviy Sensor from the plumbing
- The Resistiviy Sensor is threaded and you will need a wrench to unscrew the sensor from the plumbing
- Remove the old Resistivity Sensor
- We recommend you use some plumbing Teflon tape around the threads of the replacement Resistivity Sensor
- Carefully screw in the new sensor making sure it is snug so as not to leak around the threads
- Plug in the Resistivity Sensor electrical connection
- Test for leaks
Once the new sensor is in place and you are sure you have no leaks, then you should perform a Chemical Verification using the Scientific Solutions #3 Standardizing Solution to verify correct operation.
