Leak - Agilent Technologies 1290 Infinity 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.
