Leak; Leak Sensor Open - Agilent Technologies 1220 Infinity II LC User Manual

Leak

Error ID: 0064
A leak was detected in the module.
The signals from the two temperature sensors (leak sensor and
board-mounted temperature-compensation sensor) are used by the leak
algorithm to determine whether a leak is present. When a leak occurs, the leak
sensor is cooled by the solvent. This changes the resistance of the leak sensor
which is sensed by the leak-sensor circuit on the main board.

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.
