Measuring & 3-Phase Rotation

Measurement is made through the Meter’s terminals L1/L2/L3. Phase

Rotation directions are indicated as symbolic (LCD segments) movements on

the display. Default mode at

. Press SELECT button to toggle between

and modes.

: Hi-sensitivity mode for checking phase rotation of Motors detects

relatively low signal outputs generated spinning a motor shaft,.

: Normal-sensitivity mode for identifying phase sequence of 3-phase

MAINS supply.

Caution

Correct rotation detection relies on solid signal connection to all three test

lead terminals simultaneously. Any loose connection will lead to detection

failure and false indication. To verify signal connection and the correct

rotation indication, swap any of two signal connections l to check for

indication of reverse movement.

Hi-sensitivity mode for Motors:

Connect the test lead L1/L2/L3 to the motor connections by using probes

and/or alligator clips. Be sure the power supply is removed from the motor.

From the perspective of looking down the shaft of the motor, speedspin

it clockwise to generate sufficient signal strength for rotary detection. If

the meter indicates a clockwise movement, the motor leads connected to

L1, L2 and L3 of the meter are L1, L2 and L3 (also known as R, S and T),

respectively. If the meter indicates a counter-clockwise movement, swap any

of two motor connections and retest.
