WARNING
Some liquid and gas mixtures are dangerous. This includes
mixtures that occur because of contamination. Make sure that the instrument is
safe to use with the necessary media.
It is dangerous to ignore the specified limits for the instrument or to use the
instrument when it is not in its normal condition. Use the applicable protection
and obey all safety precautions.
To prevent a dangerous release of pressure, isolate and bleed the system before
you disconnect a pressure connection.
Do not use the instrument in locations with explosive gas, vapor or dust. There
is a risk of an explosion.
DPI 802/802P only. To prevent electrical shocks or damage to the instrument, do
not connect more than 30V between the terminals, or between the terminals and
the ground (Earth).
