PR450

Motor and Phase Rotation Tester

Introduction

Congratulations on your purchase of the Triplett PR450 Motor and Phase Rotation Tester. This

handheld instrument detects the rotational field of three-phase systems and determines motor-

rotation direction. Color-coded test leads are provided for connecting to the system or motor

under test.

Safety Procedures

To avoid possible electric shock or fire, observe the following:

Read the following information carefully before using or servicing the instrument.



Adhere to local and national safety codes.



Individual protective equipment must be used to prevent shock and injury.



Use of instrument in a manner not specified by the manufacturer may impair safety

features/protection provided by the equipment.



Avoid working alone.



Inspect the test leads for damaged insulation or exposed metal. Check test lead

continuity. Damaged leads must be replaced. Do not use the meter if it appears damaged.



Use care when working above 30V ac rms, 42V ac peak and 60V dc. Such voltages pose

a shock hazard.



When using the probes, keep fingers away from probe contacts. Keep fingers behind

the finger guards on the probes.



Measurements can be adversely affected by impedances of additional operating

circuits connected in parallel or by transient currents.



Verify operation prior to measuring hazardous voltages (voltages above 30V ac rms, 42V

ac peak and 60V dc).



Do not use the meter with any of the parts removed.



Do not use the meter near explosive gas, vapor, or dust.



Do not use the meter in a wet environment.

Operation

Determine Phase Rotation Direction

1. Connect the supplied color-coded test leads to the meter’s test lead input jacks at the top of

the meter.

2. Connect the test probes to the three mains phases for the system under test.

3. Press and Hold the ON button to turn the meter on.

4. L1, L2, and L3 indicators will illuminate for each phase connected, respectively.

5. The clockwise and counter-clockwise arrows with the left/right ‘L’ or ‘R’ icons display the

phase rotation direction (phase sequence) of mains as connected.

6. To understand the status of a test, based on the condition of the meter’s front panel LEDs, refer to

the table printed on the meter:

Note: The rotational indicator LEDs illuminate even if one of the test probes is connected to a

neutral or ground conductor instead of one of the mains phases.

Check Motor Turn Direction (contact method)

1. Connect the supplied color-coded test leads to the meter’s test lead input jacks at the top of

the meter.

2. Connect the test (alligator) probes to the three motor connections (L1 to U, L2 to V, and L3

to W).

3. Press and Hold the ON button. The green ON indicator shows that the instrument is ready

for testing.

4. Turn the motor shaft continuously in a clock-wise rotation.

*Note: you must rotate the shaft with enough speed to generate a voltage that can be detected.*

5. The clockwise and counter-clockwise arrows with the left/right ‘L’ or ‘R’ icons display

the orientation of the motor.

Check Motor Turn Direction (non-contact method)

1. Disconnect the test leads from the meter and from any other devices under test.

2. Hold the meter close (one inch or closer) to the motor,

parallel to the length of the motor shaft.

3. The bottom of the meter should face the drive shaft and the

back of the meter should be flush with the motor (refer to

diagram at right).

Note: There is an orientation symbol on the meter to assist.

4. Press and Hold the ON button. The green ON indicator

shows that the instrument is ready for testing.

5. The orientation of the motor is represented by the clockwise

and counter-clockwise arrows with the left/right ‘L’ or ‘R’

icons display. Face the rear of the motor (meter will appear upside down) when reading

the status of the display LEDs.

Note: The meter will not operate with motors controlled by frequency converters (VFDs).

Magnetic Field Detection

1. Hold the meter in the area under test.Press and hold ON button.

2. A magnetic field is present if either the clockwise or the counter-clockwise LED illuminates.

Battery replacement

The meter uses a 9V battery (supplied) as a power source. If the green LED

does not light when the ON/OFF button is pressed, replace the battery.

1. Place the meter on a clean, flat, non-abrasive surface.

2. Loosen the rear bottom Phillips head screw to access the battery

compartment.

3. Lift the battery access door and replace the 9V battery observing

polarity.

4. Place the battery carefully in the compartment without crimping

the black and red battery connecting wire.

5. Close the access door and secure the screw.
