7-3. Gas calibration method
- 43 -
NOTE
If the span adjustment failed since the reading was significantly fluctuated from the introduced gas
concentration, it returns to 2-2 after FAIL rather than PASS is displayed . In this case, the span adjustment
has not been completed.
Check if the correct concentration span adjustment gas has been provided and check the gas adjustment
tool for a gas leak. If there are mistakes, perform the span adjustment again.
If the span adjustment cannot be performed even when there is no mistake or after the correction, the gas
sensor life has expired. After turning off the power supply, please contact our overseas sales department
or local representatives.
