Extech PRT200 Non-Contact Phase Rotation Tester User Manual
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.

Questions answered in these manuals
What indicates a clockwise phase sequence?
The CW LED flashes in the direction of the arrow and the buzzer sounds intermittently.
From: Extech PRT200 Non-Contact Phase Rotation Tester User Manual
What indicates a counter-clockwise phase sequence?
The CCW LED flashes in the direction of the arrow and the buzzer sounds continuously.
From: Extech PRT200 Non-Contact Phase Rotation Tester User Manual
How do I determine the phase sequence?
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.
