Motor and Phase Rotation Indicator/English
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 Motor and Phase Rotation Indicator with any of the parts
removed.
Do not use the Motor and Phase Rotation Indicator around explosive
gas, vapor, or dust.
Do not use the Motor and Phase Rotation Indicator in a wet
environment.

Using the Motor & Phase Rotation Indicator
Determine Rotary Field Direction
To determine the rotary field direction:
1. Connect one end of the test leads to the Motor and Phase Rotation
Indicator. Make sure the L1, L2, and L3 test leads are connected to
the corresponding input jacks.
2. Connect the test probes to the other end of the test leads.
3. Connect the test probes to the three mains phases. 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.
4. The rotary indicator lights even if the neutral conductor, N, is
connected instead of the test lead input jacks. Refer to Figure 2 (also
shown on the back of the Motor and Phase Rotation Indicator) for
more information.
