Calibration should generally be implemented at the measurement pressure
to compensate for the effect of pressure differences.
The measurement pressure conditions are that of the gas being measured or the
current atmospheric pressure, which must take into account the height above sea
level of the measuring location.
Ambient temperature
The influence of changes in the ambient temperature is compensated for by the
measurement system.
However it should be kept in mind that the meter with the oxygen sensor should
be adapted to the ambient temperature. Large short-term fluctuations in the gas
temperature can considerably influence the accuracy of the display.
Water
Try to avoid getting the sensor or jack plug completely wet. Water on the gas-
sensitive surface of the oxygen sensor affects the measured result. If the device
does get wet, it can be dried on the outside with a cloth. It is recommended that
the device is not switched on until the sensor is dry.
