WARNING
When the zero adjustment is performed in the atmosphere, check the atmosphere for freshness before
beginning the adjustment. If other gases exist, the adjustment cannot be performed properly, thus
leading to dangers when the gas leaks.
<Zero Adjustment "1-1">
This is used to perform the zero adjustment.
NOTE
If the zero calibration failed since the zero point was significantly fluctuated from around zero, it returns to
1-1 after FAIL rather than PASS is displayed. In this case, the zero adjustment has not been completed.
Before starting the zero adjustment, provide the detector with the zero adjustment gas and wait until the
indicator is stabilized.
