Value Display; Displays values of the measured oxygen concentration, moisture
quantity, mixture ratio, etc
Graph Display; Displays trends of measured oxygen concentration, moisture quantity,
mixture ratio, etc.
Data Display; Displays various useful data for maintenance, such as cell temperature,
reference junction temperature, maximum/minimum oxygen
concentration, maximum/minimum moisture quantity or the like
Status Message; Indicates an alarm or error occurrence by flashing of the corresponding
icon. Indicates status such as warming-up, calibrating,or the like by
icons.
Alarm, Error Display; Displays alarms such as “Abnormal oxygen concentration”,
“Abnormal moisture quantity” or errors such as “Abnormal cell
e.m.f.” when any such status occurs.
Calibration Functions:
Automatic calibration; Requires the ZR40H Automatic Calibration Unit. It calibrates
automatically at specified intervals.
