Rated 5 out of 5 by 8reviewers.
Rated 5 out of 5 by The Fluke 789 ProcessMeter is a great tool for Automation / Process Engineers I use mine all the time for checking mA loops and load cells. I find the loop power function particularly useful for setting up a new transmitter before leaving the workshop. This meter is the only one I need in my tool bag. As with all of the Fluke equipment I have come across, the build quality is great and it is a joy to use.Check out the Fluke Milliamp Process Clamp Meters if you need to check a loop without breaking into it.
