Description
The UNI-T UT261A phase sequence tester is designed to check the phase sequence and direction of rotation in three-phase motors. It is an essential tool for electricians and technicians, used in switchboards and industrial installations where the motor’s direction of rotation must be checked with precision.
After connecting the test leads to the L1, L2, L3 terminals of the unit and to the motor leads, the LCD display quickly indicates the direction of rotation: clockwise or anti-clockwise.
