A handheld, battery-operated tool for measuring electrical parameters, supplying steady or ramping current to test process instruments, the Fluke 789 ProcessMeter provides a > 24 V loop power supply. It has all the features of a digital multimeter, plus current output capability.
As with the Fluke 787 ProcessMeter the 789 also features a DMM design to meet 1000 volt IEC 1010 CAT III standards. The 789 ProcessMeter provides a precision 1000 V, 440 mA True-rms digital multimeter, frequency measurement to 20 kHz, simultaneous mA and % of scale readout, and 20 mA dc current source / loop calibrator / simulator.
Key features of the Fluke 789 ProcessMeter:
- 24 V Loop power supply
- Large dual display
- Enhanced backlight with 2 brightness settings
- 1200 ohm drive capability on mA source
- HART mode setting with loop power and a built-in 250 ohm resistor
- 0% and 100% buttons to toggle between 4 and 20 mA sourcing for a quick span check
