DANGER
Danger of explosion due to dangerous mixture of gases!
- Before measurement close the gas path with the sealing plug, as
described below!
- If the gas path is not correctly closed with the sealing plug during
differential pressure measurement, there is a risk of unburned gas
mixture escaping.
- Escaping gas mixture can lead to an explosive atmosphere and thus
to life-threatening situations.
- Make sure there are no leaks between the sampling point and the
measuring instrument.
- Do not smoke or use naked flames during measurement, generally
avoid ignition sources.
Do not measure for longer than 5min, as a drift of the pressure sensor
means that the readings could be outside the tolerance limits.
