 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. |
| OPERATION: The 4156 PR has three individual ranges for different applications. |
| 1. In the PHASE ROTATION range, the meter is connected in the phase sequence circuit and the red terminals for phase rotatino may be used to make a phase sequence measurement. The batteries are disconnected for the testing. |
| 2. In the MOTOR range, the meter is disconnected from the phase sequence circuit and connected in the motor rotation circuit. The batteries are connected for the testing. The yellow terminals may now be used for a motor rotation test. |
| 3. In the TRANSFORMER range, the meter and batteries are connected so that the yellow terminals can be used for a transformer polarity test. It is also designed for circuit continuity tests. Users can connect test leads to L1 and L2 terminals for continuity checking. |
| DESCRIPTION: |
| 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 know is used to check continuity. |
