The Fluke 707Ex IS loop calibrator is certified in accordance with the ATEX directive for loop check applications in explosion hazardous zones. It features selectable (slow, fast, and step) ramps to provide smooth outputs for valve slewing and loop functional tests.

The internal loop supply gives you the ability to power a transmitter (up to 700Ω load) and simultaneously measure the loop current, eliminating the need to carry a DMM.

When in source mode the calibrator has >250 Ohms of series resistance and is compatible with HART devices without needing an additional series resistor.
