Functions
Display Function: Displays values of the measured oxygen concentration, etc Alarm,
Error Display: Displays alarms such as “AL-06” or errors such as “Err-01” when any
such status occurs.
Calibration Functions:
Auto-calibration; Requires the Autocalibration Unit. It calibrates automatically
at specified intervals.
Semi-auto Calibration; Requires the Autocalibration Unit. Input calibration
started by optical switch or contact, then it calibrates automatically afterwards.
Manual Calibration; Calibration with opening/closing the valve of calibration
gas in operation interactively with the optical switch.
Maintenance Functions:
Can operate updated data settings in daily operation and checking.
Display data settings, calibration data settings, test settings (current output loop
check, input/output contact check).
Setup Functions:
Initial settings suit for the plant conditions when installing the converter.
Current output data settings, alarm data settings, contact data settings, other
settings.
