Leak Sensor Short; Compensation Sensor Open - Agilent Technologies InfinityLab LC Series User Manual

6 Error Information
General Error Messages

Leak Sensor Short

Error ID: 0082
The leak sensor in the module has failed (short circuit).
The current through the leak sensor is dependent on temperature. A leak is
detected when solvent cools the leak sensor, causing the leak sensor current to
change within defined limits. If the current increases above the upper limit, the
error message is generated.

Compensation Sensor Open

Error ID: 0081
The ambient-compensation sensor (NTC) on the power switch board in the
module has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the
power switch 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 increases above the upper limit, the
error message is generated.
