Introduction
The DPI 880 Multi-function Calibrator is part of the Druck DPI
8xx series of hand held instruments.
This series of instruments 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 880 includes these functions:
Function
a Measure mA, Volts/mV, Hz/pulse count
* Supply mA, Volts/mV, Hz/pulse count
* Measure/simulate:
- a Resistance Temperature Detector (RTD):  or °C/°F
- a thermocouple (TC): mV or °C/°F
- a resistor ()
Cold Junction (CJ) compensation: Automatic/Manual
Step/Ramp functions: Automatic/Manual
Communications port: IDOS or RS232
Language selection (Refer to Table 1)
** Measure pressure/Leak test: External IDOS UPM
** Snapshot: Up to 1000 displays with a date/time stamp
250series resistor. Use this instrument together with a HART
