PRM-6 is a phase sequence and motor rotation tester designed for verifying correct motor rotation and wiring phase sequence in 3-phase systems. It features both wired and non-contact wireless motor rotation detection, with a voltage range of 40-700 V and frequency range of 16-400 Hz for phase rotation detection. The tester includes a backlit LCD display, CAT IV 600 V safety rating, and conforms to EN 61010 and EN 61557 standards. With durable rubber casing providing 3 ft (1 m) drop-proof protection, it operates at temperatures from 0°C to 40°C and altitudes up to 2000 m. Common applications include testing 3-phase power sources, identifying faulty wiring, and determining motor rotation direction in commercial and industrial environments.
