Introduction
The DPI 811 RTD (Resistance Temperature Detector)
Calibrator and DPI 812 RTD Loop Calibrator are part of the
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). Example: the Universal Pressure Module
(UPM).
The DPI 811/812 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.
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).
