Introduction

The DPI 821 Thermocouple Calibrator and DPI 822
Thermocouple 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 821/822 include these functions:
Function
Measure/simulate
thermocouple temperature
or mV
Cold Junction (CJ)
compensation
Step/Ramp functions
Communications port
Language selection
Measure pressure/Leak test
** Snapshot
Measure mA
®
HART resistor
V dc output
Switch test
Other functions
* Refer to "Specification data".
** Optional item

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.
• 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.
