Starting Semi-Auto Calibration by a Contact input
1) Confirm that on the [Input contacts] display, [Calibration Start] is selected.
2) In Measurement mode (with the Basic display displayed) when the contact input is
detected then Calibration starts.
3) To abort calibration, touch the reject key (door with arrow icon). If you abort Span
or Zero calibration then calibration time is skipped and stabilization (settling) time
starts. After that touch the reject key (door with arrow icon) again, stabilization
(settling) time is skipped and abort calibration completely. If you touch the enter key
during stabilization (settling) time, abort calibration of corresponding channel and
next channel calibration will be started.
9.3.3 Starting AutoCalibration
No user action is required to start autocalibration. Autocalibration starts at the preset
time and is repeated at the preset interval.
Note
Before starting Semi-Auto calibration or AutoCalibration, operate the calibration gas
solenoid valves and adjust calibration gas flow to 600
Ϯ60ml/min for each sensor.
If you skip Hold time, the "output hold" for output stabilization is released immedi-
ately after Calibration time ends. (However, in this case, if "output hold" under
maintenance status is set to "enable", the "output value" is constant after Calibration
time ends. ) If stabilization time is skipped and if calibration gas still remains in the
sensor, the gas affect the accuracy of the output.
