Phase Rotation Tester
Introduction
Congratulations on your purchase of the Triplett PR400 Phase Rotation Tester. This handheld
instrument detects the phase rotation of three-phase systems. Color-coded test leads are
provided for connecting to the three mains phases of the system under test.

Safety Procedures
To avoid possible electric shock or fire, observe the following:
Read the following 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. Damaged
leads must be replaced. Do not use the phase Rotation indicator if it appears damaged.
Use care 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 meter in a wet environment.

Operation
Determine Phase Rotation Direction
1. Connect the supplied color-coded test leads to the meter’s test lead
input jacks at the top of the meter.
2. Connect the test probes to the three mains phases for the system under
test.
3. L1, L2, and L3 indicators will illuminate one at a time, on the
meter’s LCD display, as each phase is connected.
4. The clockwise and counter-clockwise arrows with the left ‘L’ or right ‘R’
icons display the phase rotation direction of the device under test.
Note: The rotational arrow indicators illuminate even if one of the test
probes is connected to a neutral or ground conductor instead of one of
the mains phases.
