INTRODUCTION
Motor and Phase Rotation Indicator is a handheld, battery-operated instrument designed to
detect the rotary eld of three-phase systems and determine motor-rotation direction.
Protection provided by the instrument will be impaired if used in a manner not specied by
the manufacturer.
SAFETY INFORMATION
CAUTION
Identies conditions and actions that may damage the apparatus.
WARNING
Identies conditions and actions that pose hazard(s) to the user.
Read rst
Safety information. To avoid possible electric shock or r, do the following:

features/protection provided by the equipment.
• Avoid working al one.
• 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.
• Be careful when working above 30 VAC rms, 42 V ac peak and 60 VDC. Such voltages
pose a shock hazard.
• When using the probes, keep ngers away from probe contacts. Keep ngers behind the
nger guards on the probes.
• Measurements can be adversel y aected 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 VAC peak and 60 VDC).
• 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.

MAINTAINING THE APPARATUS
This section provides basic maintenance information.
CAUTION
To avoid damaging the apparatus:
• Do not attempt to repair or service the apparatus unless qualied to do so.
• Make sure that the relevant calibration, performance test, and service information

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 qualied recycler or hazardous materials handler.
The apparatus uses a 9 V battery (supplied).
To replace the battery, follow these steps and refer to Fig. 1:
1. Disconnect test leads from any power source.
2. Place the apparatus face down on a non abrasive 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 Fig. 1.
Observe the battery pol ari ty 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.
