Sensor troubleshooting

This section describes manual tests that can be performed on the sensor to verify the health
of individual components. The tests will require the use of a digital multimeter capable of
measuring conductance in nanosiemens and an LCR meter. A sensor circuit diagram is
shown in

. The tests described below will check for continuity or isolation of the

internal components of the sensor.
