Functions (inclused Humidity Analyzer)
Display Function: Displays values of the measured oxygen concentration, moisture
quantity, mixture ratio, etc.
Alarm, Error Display: Displays alarms such as “AL-06” or errors such as “Err-01” when any
such status occurs.
Calibration Functions:
Automatic calibration; Requires the Automatic Calibration Unit. It calibrates
automatically at specified intervals.
Semi-auto Calibration; Requires the Automatic Calibration Unit. Input calibration start
signal 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.
