Introduction
The DPI 820 Dual Input Thermometer is part of the GE Druck
DPI 800 series of hand held instruments.
The DPI 800 series uses Intelligent Digital Output Sensor (IDOS)
technology to give instant plug and play functionality with a
range of Universal Measurement Modules (UMM).
The DPI 820 includes 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, 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
• 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.
• Do not use the instrument in locations with explosive
gas, vapor or dust. There is a risk of an explosion.
• 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).
• UMM - Pressure options only. To prevent a dangerous
release of pressure, isolate and bleed the system before
you disconnect a pressure connection.
