User's Guide Non-Contact Phase Rotation Tester Model PRT200
Introduction Congratulations on your purchase of this Extech Meter. The PRT200 is used to quickly and accurately determine three phase sequence for motor installation and repair. The non-contact voltage detecting technique permits easy connection to insulated conductors, avoiding uncertain and difficult connections to bare high voltage wires. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

Operation Note: Before proceeding, read all safety notes. 1. Press the power switch to turn on the instrument. All of the LEDS will flash for a 2 second test. Only the power LED will remain on after the test. Do not use the instrument if any of the LEDs do not work. 2. Connect the three non-contact alligator clips to the three phase power conductors. Red to L1 (R, U) White to L2 (S, V) Blue to L3 (T, W) 3. The “▼” symbol on each clip should be placed at the center of each conductor. 4.
Maintenance Battery Replacement When the ON LED begins to flash, the batteries need to be replaced. 1. Remove the clips from any conductors. 2. Remove the screw holding the battery compartment cover and remove the cover. 3. Replace the four AA batteries. 4. Replace the battery cover.
