The zero calibration steps are as follows:
1: Press the "MENU" key on the remote controller, then
instrument displays F-01.
2: Press "+" key or "-" key to adjust to F-04.
3: Press the "OK" key to display the current gas concentration
reading. Wait until the instrument value is stabilize, press the "OK" key
again, then detector reading will display "PASS", indicating that the
calibration is successful.

Span calibration
Connect the calibration gas cylinder of known concentration to the calibration cap (Optional) of the
instrument(as shown in the figure below) through PTFE pipe.
This operation is mainly divided into two steps: [Set Calibration Point] and [Span Calibration].
Note: After the calibration, please remove the calibration cap. Do not install the calibration cap
on the detector during testing.
