Safety
Before you use the instrument, make sure that you read
and understand all the related data. This includes: all local
safety procedures, the instructions for the UMM (if
applicable), and this publication.
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).
Before you start an operation or procedure in this
publication, make sure that you have the necessary skills
(if necessary, with qualifications from an approved training
establishment). Follow good engineering practice at all
times.
