Yes, it comes with alligator clips.

What is ProcessMeter?

Process metres are excellent instruments that can measure, display, alert, and regulate a wide range of process variables. They have 4-20 mA and 0-10 V analogue inputs.


The Fluke 789 ProcessMeter includes all of the standard Digital Multimeter capabilities, including frequency measurement to 20 kHz, Max/Min/Average/Hold/Relative modes, diode test, and a continuity beeper. Combining it with the ability to debug each component of the loop is a powerful combination.

The multimeter’s accuracy and resolution are excellent for general-purpose use. This is an excellent multimeter, in my opinion. I hope the reader of this post takes away some useful information.
