Semi-automatic calibration
During a sensor module calibration, the central controller blocks the alarms from the module in
question and displays a maintenance key on the screen. Up to 10 sensors can be calibrated at the
same time. The concentration level for the calibration gas is stored in the sensor’s memory.
Each calibration start and stop is logged as an event.
The printer records a state after the calibration of each sensor (cf : Printing).
If the calibration is failed, the sensor is listed as faulting and an event is logged with a fault code
(0010 – calibration zero fault, 0020 = calibration sensitivity fault) .
