The handheld Fluke 789 is a process meter with mA source. This test tool offers standard multimeter functions with a 2–20 mA sink and source capability. It also includes simultaneous mA and percentage of scale readout (on mA output) with a 25% manual step and 0.1% VDC accuracy. It is available to rent from TechRentals.
The meter provides a current output and is useful for measuring electrical parameters, supplying steady or ramping currents, and for measuring input impedance, ranges and diodes. It provides a 24 V loop power supply and a HART mode setting with loop power (adding a 250Ω resistor).
The double-sized, dual display and backlight makes readings easy, and 0–100% mA span check buttons toggle between 4 and 20 mA.
