Leak Sensor Open; Compensation Sensor Open - Agilent Technologies 1260 User Manual

Leak Sensor Open

The leak sensor in the module has failed (open 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 falls outside the lower limit, the
error message is generated.

Compensation Sensor Open

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