Leak Sensor Open; Compensation Sensor Open - Agilent Technologies Infinity II 1290 User Manual

Leak Sensor Open

Error ID: 0083
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

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.
