4-5. Performing air calibration
- 22 -
NOTE
•
Perform air calibration under the pressure and temperature/humidity conditions close to those in the
operating environment or in the fresh air.
•
Perform air calibration after the reading is stabilized.
•
If there is a sudden temperature change of 15ºC or more between the storage and operational
locations, leave the gas detector in the operating environment (in the fresh air or place filled with
purge air) for ten minutes or so to make it adapt to the environment before performing air
calibration.
