Introduction
The DPI800 Pressure Indicator and DPI802 Pressure Loop
Calibrator are part of the Druck DPI800 series of hand held
instruments.
The DPI800 series uses Intelligent Digital Output Sensor
(IDOS) technology to give instant plug and play
functionality with a range of Universal Measurement
Modules (UMM). Example: the Universal Pressure Module
(UPM).
The DPI800/802 include these functions:
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.
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.

WARNING
Do not use with media that has
an oxygen concentration > 21 % or other
strong oxidizing agents.
This product contains materials or fluids that
may degrade or combust in the presence of
strong oxidizing agents.
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.
DPI802/802P 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).
