Compensation Sensor Open; Compensation Sensor Short - Agilent Technologies 1290 User Manual

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.
