Description
The Extech 480403 three-phase and motor rotation tester has a nominal range of 40 volts to 600 volts for testing the phase orientation of three-phase power supplies in a frequency range of 2 Hz to 400 Hz. LEDs indicate phase orientation (clockwise or counterclockwise) and whether each phase is active. It also indicates the direction of motor rotation to ensure that it is not damaged by incorrect wiring.
