Fluke 789 ProcessMeter™

The Fluke 789 ProcessMeter is the ultimate troubleshooting tool for electricians and instrumentation professionals.  It combines the functionality of a full-featured loop calibrator with the power of a CAT III 1000 V, CAT IV 600 V safety rated digital multimeter, and the wireless capabilities of Fluke Connect connectivity with optional IR3000FC module.  The 789 has a large, dual display with two levels of backlighting and externally accessible fuse and batteries for easy replacement.  And its built-in, selectable 250-ohm HART® resistor eliminates the need to carry a separate resistor.

The 789 also has a built-in-24-Volt loop supply, which reduces the need to carry a separate power supply when doing offline transmitter testing.  You can also add 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.

*Requires Fluke IR3000FV module (not included).

The 789 provides all standard DMM capabilities including frequency measurement to 20 khz, Min/Max/Average/Hold/Relative modes, and diode test and continuity beeper.  Combine that with the ability to troubleshoot every part of the loop.

Measure, source, simulate 4-20 mA signals, measure resistance, measure power, provide power to the loop and provide 250-ohm resistance to the loop.  The 789 includes SpanCheck; 0% and 100% buttons to toggle between 4 and 20 mA sourcing, while the display can simultaneously show mA and % of scale readings for faster troubleshooting.  It also delivers 1200-ohm drive capability on mA source.

This ProcessMeter offers manual step, 100%, 25%, Coarse, Fine, plus auto step and auto ramp.  It also delivers 0.1% DV voltage accuracy and 0.05% DC current accuracy.
