• 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.

Warning
The rotary indicator lights even
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 leads 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.
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.

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.

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
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. Remove the holster.
3. Place the apparatus face down on a nonabrasive
surface and loosen the battery-door screw with
a flat-blade screwdriver.
4. Lift the battery access lid away from the apparatus.
5. Replace the battery as shown in Figure 4.
Observe the battery polarity shown in the battery
compartment.
6. Secure the battery access lid back in position
with the screw.
7. Place the apparatus back in the holster.
