CAUTION
To protect yourself, think "Safety First":
• Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.
• Use appropriate personal protective equipment such as safety glasses, face shields, insulating gloves, insulating
boots, and/or insulating mats.
• Use the proper terminals for your measurements.
• Never ground yourself when taking electrical measurements.
• Always work with a partner.
• When using the probes, keep fingers as far behind the probe tips as possible.
OPERATING INSTRUCTIONS:
Determination of the rotary field direction and phase presence:
On a 3 Phase System, the sequence of the 3 phases determines the rotation of a 3 phase motor connected to that
system. The correct 3 phase sequence results in a clockwise rotation of a connected motor.
• Insert the test leads to the matching color coded sockets of the instrument. Red to R, White (or yellow) to S,
Blue (or black) to T.
• Clip the test probes to the three phases (R,S,T). When connecting to a voltage greater than 100VAC,
the corresponding neon lamp will start to glow, indicating the presence of the voltage on its corresponding lead
(R,S,T lamps).
• Press the TEST button to turn the instrument "ON". The green LED indicates that the instrument is ON and is
testing. The battery is OK when the green "
depressing the TEST button, replace the battery (see Battery Replacement).
If the LED L1-L2-L3 is illuminated, a clockwise rotary field is present.
If the LED L2-L1-L3 is illuminated, a counter clockwise rotary field is present.
Please note that the phase voltage is indicated even if the neutral conductor N is connected in place of a
phase conductor.
Determination of motor connections and motor rotation:
• Insert the test leads into the instrument using the color codes then to the motor wiring per the chart below.

Turn the motor shaft by at least a half rotation clockwise. Look at the LED's while the shaft is spinning.
Note: A relatively low RPM is sufficient to perform the measurement.
It is important to ensure that the user faces the drive shaft, looking toward the motor and the front side of the
tester at the same time, so that motor rotation can be confirmed.
The red LED L1-L2-L3 indicates clockwise motor rotation if the leads are properly connected as follows: L1 to R,
L2 to S, and L3 to T.
The red LED L2-L1-L3 indicates counter- clockwise motor rotation if the leads are improperly connected, such as
L1 to R, L2 to S, and L3 to T. Switch the red and white test lead connections and confirm the proper clockwise
rotation now exists.
