Motor & Phase Rotation Indicator
1.Introduction
The Motor and Phase Rotation indicator is a handheld, battery-operated instrument designed to
detect the rotary field of three-phase systems and determine motor-rotation direction.
2.Safety Information
CAUTION identifies conditions and actions that may damage the phase rotation indicator.
WARNING identifies conditions and actions that pose hazard to the user.
To avoid possible electric shock or fire, do the following:
• Read the following safety 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,
damage leads must be replaced, do not use the phase Rotation indicator if it looks damaged.
• Be careful 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 phase rotation indicator with any of the parts removed.
• Do not use the phase rotation indicator around explosive gas, vapor, or dust.
• Do not use the phase rotation indicator in a wet environment.

6.Operation
6-1.Determine Rotary Field Direction
1.Connect one end of the test leads to the Motor and Phase Rotation indicator, make sure the L1,
L2 and L3 test leads are connected to the corresponding input jacks.
2.Connect the test probes to the other end of the test leads.
3.Connect the test probes to the three mains phases, press the ON/OFF Button, the green ON
indicator shows that the instrument is ready for testing.
4.Either the Clockwise or Counter Clockwise Rotary indicator illuminates showing the Type of rotary
field direction present.
5.The rotary indicator lights even if the neutral conductor, N, is connected instead of the Test lead
input jacks.
6.Refer to Figure (Also shown on the back of the Motor and Phase Rotation indicator) for more
information.

Motor & Phase Rotation Indicator
6-2.Non-Contact Rotary Field Indication
1.Disconnect all test leads from the Motor and Phase Rotation indicator.
2.Position the Indicator on the motor so that it is parallel to the length of the motor shaft, the
Indicator should be one inch or close to the motor.
3.Press the ON/OFF Button, the green ON indicator shows that the instrument is ready for testing.
4.Either the Clockwise or Counter Clockwise Rotary indicator illuminates showing the type of rotary
field direction present.
Note: The indicator will not operate with engines controlled by frequency converters. The bottom
of the Motor and Phase Rotation indicator should be oriented towards the drive shaft. See the
Orientation Symbol on the Motor and Phase Rotation indicator.
See Table for the minimum motor diameter and number of pole pair to obtain a reliable test result.

6-3.Determine the Motor Connection
1.Connect one end of the test leads to the Motor and Phase Rotation indicator, make sure the L1,
L2 and L3 test leads are connected to the corresponding jack.
2.Connect the alligator clamps to the other end of the test leads.
3.Connect the alligator clamps to the motor connections, L1 to U, L2 to V, L3 to W.
4.Press the ON/OFF Button, the green ON indicator shows that the instrument is ready for testing.
5.Turn the motor shaft half a revolution towards the right.
Note: The bottom of the Motor and Phase Rotation indicator should be oriented towards the drive
shaft. See the Orientation Symbol on the Motor and Phase Rotation indicator.
Note: Either the Clockwise or Counter Clockwise Rotary indicator illuminates showing the type of
rotary field direction present.
6-4.Magnetic Field Detection
• To detect a magnetic field, place the Motor and Phase Rotation indicator to a solenoid valve.
• A magnetic field is present if either the Clockwise or the Counter Clockwise Rotary indicator
illuminate.
7.Battery Replacement
The Motor and Phase Rotation indicator uses a 9V battery (supplied), To replace the battery,
follow these steps.
1.Place the Motor and Phase Rotation indicator face down on a nonabrasive surface and loosen
the battery-door screw with a screwdriver.
2.Life the battery access lid away from the Motor and Phase Rotation indicator.
3.Observe the battery polarity shown in the battery compartment.
4.Secure the battery access lid back in position with the screw.
Note: The Motor and Phase Rotation indicator contains alkaline batteries. Do not dispose of these
batteries with other solid waste. Used batteries should be disposed of by a qualified recycler or
hazardous materials handler.
