Product overview: Fluke 789 ProcessMeter™

Fluke 789 ProcessMeter doubles your troubleshooting power and is Fluke Connect-enabled

The Fluke 789 ProcessMeter is the ultimate troubleshooting tool for electricians and instrumentation professionals. It combines the functionality of a loop calibrator with the power of a digital multimeter, and the wireless capabilities of Fluke Connect connectivity with optional IR3000FC module. The 789 has a display that's not only twice as large as the Fluke 787B, but also twice as bright with two levels of backlighting. And its built-in, selectable 250 ohm HART® resistor eliminates the need to carry a separate resistor.

The 789 also has a 24-Volt loop supply, which reduces the need to carry a separate power supply when doing offline transmitter testing. You can add an optional temperature measurement module and the wireless data logging capabilities of the Fluke Connect™ mobile app to log data wirelessly to your smart phone and review it from a remote location. So now process technicians can do a lot more while carrying a lot less.

Other useful features:

  • Includes 0% and 100% buttons to toggle between 4 and 20 mA sourcing for a quick span check
  • Provides all standard DMM capabilities including frequency measurement to 20 kHz, Min/Max/Average/Hold/Relative modes, and diode test and continuity beeper
  • Simultaneous displays mA and % of scale readings
  • Provides 20 mA DC current source/loop calibrator/simulator
  • Offers manual step (100%, 25%, Coarse, Fine) plus auto step and auto ramp
  • Delivers 0.1% dc voltage accuracy and 0.05% dc current accuracy
  • Provides 1200 ohm drive capability on mA source
  • Offers HART mode setting with loop power and a built-in 250 ohm resistor
  • Offers externally accessible fuses and batteries for easy replacement

Reviews: Fluke 789 ProcessMeter™

Rated 5 out of 5 by from Nice meter This is the second 789 meter that I have purchased. I liked the features of mA sourcing built into multimeter that I ordered a second unit. One less tool to carry around.

Rated 5 out of 5 by from A Powerful Tool I purchased my 789 a few years ago and have never looked back. It is a solid tool for testing I/O and calibrating sensors. It is the only multi-meter that I carry other than the 773 Clamp Meter.

Rated 5 out of 5 by from Nice Meter A very useful meter for process control. I can carry only one meter and do both 4-20 miliamps (measure, source and sink) and electrical testing. It is durable and rugged. Easy to see display. It can also do remote testing so I don't have to do arc flash protocol. My favorite meter.

Rated 5 out of 5 by from Fluke's Legendary Quality My experience with Fluke products has made me come to rely on them for my job. I've used this meter for years in the field and liked it so much, I bought one for my personal use. It is great for controls engineers during installation and testing.

Rated 5 out of 5 by from Analog testing Used for testing 4-20 ma analog input module calibration. Easily setup to step through the ranges needed and determine bad modules. It is nice to have this functionality included in a meter that I would carry anyway.

Rated 5 out of 5 by from 789 Speeds Up Troubleshooting We use our 789 mostly for the ability to loop power 24vdc instruments and to send 4-20ma signals into our PLCs. This definitely reduces the amount of time spent troubleshooting issues by quickly allow us to separate issues between the instrument or the PLC side. The meter is one of the most cost effective tools we have in our toolbox for checking instrumentation and wiring.

Rated 5 out of 5 by from The tool I use the most I used to use a Fluke 87V DMM and a separate signal generator for process calibrations and troubleshooting. This meter combines both and is invaluable to me being able to perform my job quickly and efficiently. The built-in 250 ohm resistor feature is nice for HART communications too.

Rated 5 out of 5 by from Great Tool! I bought this about 1 year ago and it has worked flawlessly every sense. I use it almost every day for voltage, resistance, and to simulate/ measure 4-20ma. IT has held up to harsh elements in all sorts of process manufacturing.
