Ensuring System Wellness (IC Devices)
Testing the Leak Detector

Many System Wellness supported devices are equipped with leak detectors. The test procedure for all of the sensors of IC devices is the same.

1. Thoroughly dry the sensor.

2. Open the System Wellness Control Panel for the device (see  Opening a Wellness Control Panel).

3. Under Diagnostic Tests, leak detector, select the internal script button to test the sensor installed in the device itself. Select external to test the sensor on a controlled device. For example, for a pump, internal refers to the sensor in the pump and external refers to the sensor in a chromatography oven controlled by the pump.

4. The device tests the sensor and reports the results to Chromeleon. Possible test results are:

• Passed (Dry)

• Failed (Wet)

• Failed (Open circuit): The sensor may be disconnected. Check the connection.

• Failed (Short circuit): The sensor may need replacing. Contact Dionex for assistance.

• Failed (Out-of-calibration): Calibrate the sensor (see Calibrating the Leak Detector) and retest. If the test still fails, the sensor may need replacing. Contact Dionex for assistance.
