This document describes the features and characteristics of the Extech PRT200 non-contact phase rotation tester, including fast and accurate phase rotation sequence determination, non-contact voltage detection technology, etc.
The Extech PRT200 is a device used to quickly and accurately determine the phase rotation sequence of live three-phase circuits. It utilizes non-contact voltage detection technology, allowing users to connect to insulated wires without the uncertainty and difficulty associated with exposed high-voltage conductors.
The manual details safety precautions, instrument description, operation steps including LED indicators and buzzer signals for CW/CCW sequences, and maintenance procedures such as battery replacement using four 1.5V AA batteries. This manual is written in Chinese.
