Phase and Motor Rotation Tester
Applications:The 4156 PR is used to identify the leads of a disconnected motor so that when the motor is in true phase sequence, it will run in the desired direction. The identification process is necessary before a motor can be connected. The tester is also used to identify true phase sequence of energized AC power lines up to 600 AC volts. The other functions of the 4156 PR include the determination of transformer polarity and testing of circuit continuity.The three red terminals on the right side (R,S,T) are used to connected to energized AC power systems up to 600 volts. The other three yellow terminals on the left side (L1, L2, L3) are for connection to de-energized equipment. Do not connect to Live Voltage!The Momentary Test push-button is used to identify transformer polarity. Deflection of the rotation pointer indicates transformer polarity. Read either Subtractive on the right or Additive to the left. The Zero Adjustment knob is used to check continuity.
