Auto Calibration (Option) - Fuji Electric ZKME Instruction Manual

Description
 Calibration is performed at time intervals set in advance.
 The solenoid valve is driven by contact signal to feed the standard gas for automatic calibration with
span gas and zero gas.
 "CAL" is displayed on the left of the measurement screen during automatic calibration.
 If the output signal hold is set, the output signal is held to the set value during calibration.
After the calibration, the hold is maintained until the time set in the measurement waiting time
elapses.
 For automatic calibration, it is necessary to set "10.2.2 Date and time for starting automatic
calibration (option)", "10.2.3 Cycle time setting of automatic calibration (option)", "10.2.7
Calibration gas setting".
 To perform sensor maintenance (sensor check, sensor recovery), "10.4.7 Sensor check setting for
calibration (option)" and "10.4.8 Sensor recovery setting for calibration (option)" are required.
 Refer to Sections "4.3" and "4.4" for the wiring of solenoid valves.
