Determine the Rotary Field Direction
To determine the rotary field direction:
1. Connect the test probes to the end of the
test leads.
2. Connect the test probes to the three mains
phases.

3. The green ON indicator shows that the
instrument is ready for testing.
4. Either the cloc wise or counter-cloc wise
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 jac s.
Unpac ing the phase Rotation

The phase Rotation indicator ships with the
following items:
3 pieces self-retaining test probes
Alligator clip

Read First: Safety Information
To avoid possible electric shoc 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 shoc and injury.
Use of instrument in a manner not specified by
the manufacturer may impair safety
features/protection provided by the equipment.
Avoid wor ing alone.
6
Inspect the test leads for damaged insulation or
exposed metal. Chec test lead continuity. Damage
leads must be replaced. Do not use the phase
Rotation indicator if it loo s damaged.
Be careful when wor ing above 30V ac rms,
42V ac pea and 60V dc. Such voltages pose a
shoc hazard.
When using the probes, eep 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 pea
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.
