Fluke 789 ProcessMeter™ with 250 Ohm HART resistor

The Fluke 787 was the first tool to combine a DMM and a loop calibrator to give process technicians double the power in one tool.

 

Double Your Power

The Fluke 787 was the first tool to combine a DMM and a loop calibrator to give process technicians double the power in one tool. Now it’s even better, the range is extended with the new Fluke 789 – the ultimate loop calibration multimeter. The Fluke 789 has a 24-Volt loop supply reducing the need for taking a separate power supply when doing offline transmitter testing. And with its built-in, selectable 250-Ohm Hart® resistor, it also eliminates the need to carry a separate resistor with you. Now process technicians can do a lot more while carrying a lot less.

Features of the Fluke 789

  • 24 V Loop power supply
  • Very 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
  • Externally accessible fuses for easy replacement
  • Infrared-port to process data in FlukeView Forms (V2.1) software
  • Fluke 789 features that are also included in the Fluke 787
  • Precision 1000 V, 440 mA True-RMS digital Multimeter

  • Frequency measurement to 20 kHz
  • Min/Max/Average/Hold/Relative modes
  • Diode Test and Continuity Beeper
  • Simultaneous mA and % of scale readout
  • 20 mA DC current source / loop calibrator / simulator
  • Manual Step (100%, 25%, Coarse, Fine) plus Auto Step and Auto Ramp
  • Externally accessible battery for easy battery changes
