” key to select “Enter” to confirm the zero calibration. The zero calibration
for this sensor is finished.
Attention:
If failed in zero calibration, please recalibrate in clear air. If failed
again, please contact local agent or manufacturer.

Gas Sensibility Calibration
(For oxygen, it is zero calibration with the standard value of 0.0%vol.)
For all gas sensors, the gas sensibility calibration should be operated once every
6 to 12 months at least. User should calibrate a sensor with one kind of
calibrating gas, the device will operate calibration automatically.
Below calibration tools are needed for calibration,
