Introduction
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.
Protection provided by the instrument will be
impaired if used in a manner not specified by the
manufacturer.
Motor and Phase Rotation Indicator ships with the
following items:
• 3 test probes
• 3 alligator clips
• 9 V battery
• Users Manual
If an item is damaged or missing, contact the place
of purchase immediately.

Safety Information
• 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
apparatus if it looks damaged.
identifies conditions and actions that may
damage the apparatus.
CAUTION
identifies conditions and actions that pose
hazard(s) to the user.
WARNING
Safety Information To avoid possible
electric shock or fire, do the following:
Read First

03 04
Symbols
• Be careful when working above 30 V ac rms, 42 V
ac peak and 60 V 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 on a known source prior to
measuring hazardous voltages (voltages above
30 V ac rms, 42 V ac peak and 60 V dc).
• Do not use the apparatus with any of the parts
removed.
• Do not use the apparatus around explosive gas,
vapor, or dust.
• Disconnect the test leads from power sources and
the apparatus before changing the battery.
• Do not use the apparatus in a wet environment.
The following symbols appear on the Motor and
Phase Rotation Indicator or in this manual.

WARNING
if the neutral conductor, N, is connected instead
of L1, L2, or L3. Refer to Figure 2 (also shown on
the face of the apparatus) for more information.
Figure 2. Phase Indication Table (shown on the
face of the apparatus)
Non-Contact Rotary Field Indication
For non-contact rotary field indication:
1. Disconnect all test probes or alligator clips from the
apparatus.
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 closer to the motor.
See Figure 3.
The rotary indicator lights
Note
The Indicator will not operate with engines
controlled by frequency converters. The bottom of
the apparatus should be oriented towards the drive
shaft. See the Orientation Symbol on the apparatus.
Figure 3. Motor Rotation
See Table 2 for the minimum motor diameter and
number of pole pair to obtain a reliable test result.
3. Press the ON/OFF button. The green ON indicator
shows that the instrument is ready for testing.
Either the Clockwise or Counter Clockwise Rotary
indicator illuminates showing the type of rotary
field direction present.

Table 2. Reliable Motor Test Requirements
Determine the Motor Connection
1. Connect the alligator clips to the other end of
the test leads.
2. Connect the alligator clips to the motor
connections, L1 to U, L2 to V, L3 to W.
3. Press the ON/OFF button. The green ON indicator
shows that the instrument is ready for testing.
4. Turn the motor shaft half a revolution towards
the right.
Note
The bottom of the apparatus should be oriented
towards the drive shaft . See the Orientation
Symbol on the apparatus.
Either the Clockwise or Counter Clockwise Rotary
indicator illuminates showing the type of rotary
field direction present.

Magnetic Field Detection
To detect a magnetic field, place the apparatus to
a solenoid valve. A magnetic field is present if
either the Clockwise or the Counter Clockwise
Rotary indicator illuminate.
Maintaining The Apparatus
This section provides basic maintenance
information.
To avoid damaging the apparatus:
• Do not attempt to repair or service the
apparatus unless qualified to do so.
• Make sure that the relevant calibration,
performance test, and service information
is being used.
Caution
Cleaning
Periodically wipe the case with a damp cloth and
mild detergent. Clean only with soap and water and
remove any residue afterwards.
Caution
To avoid damaging the apparatus:
• Do not use abrasives or solvents. Abrasives
or solvents will damage the apparatus case.
• Prior to cleaning, remove test leads from the
apparatus.
Replacing And Disposing Of The Batteries
Warning
To avoid electric shock, disconnect the test
leads from the source before opening the
apparatus for battery replacement.
Note
The apparatus 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.

13 14
The apparatus uses a 9 V battery (supplied).
To replace the battery, follow these steps and refer
to Figure 4:
1. Disconnect test leads from any power source.
2. Place the apparatus face down on a nonabrasive
surface and loosen the battery-door screw with
a screwdriver.
3. Lift the battery access lid away from the apparatus.
4. Replace the battery as shown in Figure 4.
Observe the battery polarity shown in the battery
compartment.
5. Secure the battery access lid back in position
with the screw.
6. Place the apparatus back in the holster.
