## Overview

The Extech PRT200 is a robust non-contact phase sequence tester designed for professionals needing quick, accurate phase orientation and live phase detection across a wide voltage and frequency range. Its durable housing, magnetic back, and insulated wide-jaw clips make it an indispensable tool for efficient, safe electrical diagnostics.

## Description

Tests up to 1000VAC with visual/audible indication. 75 to 1000VAC input voltage with 45 to 65Hz frequency range. LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each phase is live. Beeper sounds intermittently when correct phase is detected and continuously if phase is reversed. Durable housing with back cover magnet for attachment to an AC distribution panel for easy measurement. Adjustable Hi/Lo LED brightness switch for making measurements in dimly lit areas or sunlight. Fully insulated alligator clips with wide jaws. Low battery warning. Complete with three built-in 30" test leads with large color-coded alligator clips, four AA batteries, and pouch case

## Questions & Answers

**Q: Will this work on 4/0 wire?**
A: Yes I personally used it on 750MCM which is 5 times the diameter of 4/0. This is a great phase rotation meter.

**Q: Does it work on 480-V delta and wye systems?**
A: Yes.
It has worked perfectly on all systems and all voltages up to and including 480 for us.

Excellent tool and much safer.

**Q: Will this work on the output of a VFD?**
A: It should as long as the VFD is running (being commanded to go a direction at 50-60 HZ)

**Q: Can this be used on single phase 240 volt service?**
A: Hi, phase sequence is only used to determine the correct phasing of the 3 phase supply.  You need not use this device for single phase at all.  You only need a volt meter to ensure that the supply is in order in terms of L N E.
