Extech PRT200 non-contact phase rotation tester is used to quickly and accurately determine three phase sequence for motor installation and repair. The meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
The Extech PRT200 is a non-contact phase rotation tester designed to quickly and accurately determine three-phase sequence for motor installation and repair. It utilizes a non-contact voltage detecting technique that allows for easy connection to insulated conductors, avoiding the need to touch bare high voltage wires. The device is shipped fully tested and calibrated to provide reliable service.

Connect the three non-contact alligator clips to the three phase power conductors; the CW or CCW LED and rotation LEDs will indicate the phase sequence.
The buzzer sounds intermittently for a clockwise sequence and continuously for a counter-clockwise sequence.
You should replace the batteries when the ON LED begins to flash.
The unit automatically shuts off after 5 minutes of inactivity to extend battery life.
