The Amprobe PRM-4 Phase Sequence and Motor Rotation Tester is a 2-in-1 precision electrical test tool that is perfect for installing conveyor lines, pump systems, and interconnected drivers. This PRM-4 tester accurately measures the phase sequence of a three-wire system, checks open phase and measures motor shaft rotation with the use of a nine-volt battery. It features a three-phase load of nearly seven milliamps per phase of AC power source.
This Amprobe phase sequence and motor rotation tester has a safety rating of CAT III 600 V for safety purposes. Also, it offers a 45 to 70-Hertz frequency when doing the phase sequence function. Plus, the PRM-4 provides ten minutes operating time for both phase sequence and motor rotation functions.
The PRM-4 phase sequence and motor rotation tester use LED indicators to show current status. Weighing only 0.4 pounds, it measures 6.02" H x 2.83" W x 1.37" D. In addition, the Amprobe PRM-4 is CE and cCSAus agency approved.
