The 787/789 Process Meter is a DMM and Loop Calibrator in one rugged, handheld tool.
The 789 with its built-in 24 V loop supply reduces the need for taking a separate power supply when doing offline transmitter testing.

• Precision 1000 V, 440mA True RMS Multimeter
• DC current source and Loop Calibrator
• Simultaneous mA and percentage scale readout
• HART mode setting with loop power and built-in 250 ohm resistor (789)
