1100 Series DAD and MWD Reference Manual 63
Troubleshooting and Test Functions 3
Compensation Sensor Short
The ambient-compensation sensor (NTC) on the detector main board in the
detector has failed (short circuit).
The resistance across the temperature compensation sensor (NTC) on the
detector main board is dependent on ambient temperature. The change in
resistance is used by the leak circuit to compensate for ambient temperature
changes. If the resistance across the sensor falls below the lower limit, the
error message is generated.
Probable Causes
• Defective detector main board.
Suggested Actions
✔ Exchange the detector main board.
