Phase Sequence and Motor Rotation Indicator UT261A

Phase Sequence and Motor Rotation Indicator UT261A
The UT261A phase sequence detector is used to check the order of connection of phase conductors to three-phase motors, where the direction of rotation must be observed. After connecting the three supplied test leads to the L1, L2, L3 sockets on the UT261A and the other end with crocodile clips on the motor lead wires, the LCD display shows the direction of rotation of the motor axis clockwise or counterclockwise.
