Determination of the rotary field direction and
phase presence
On a 3 Phase System, the sequence of the 3 phases
determine the rotation of a 3 phase motor connected
to that system.
The correct 3 Phase Sequence L
1
, L
2
, L
3
results in a
clockwise rotation of the connected motor.
Connect the Test Leads to the sockets of the
Instrument, respecting the correct color. Red to L
1
,
Yellow to L
2
, Blue to L
3
.
Clip the test probes to the Powered three mains
phase, L

.
When connecting to a voltage superior to 40V AC, the
corresponding LCD Indicator will show, indicating the
presence of the voltage on it's corresponding lead (L

LCD).
If the LCD (Right arrows) L

is illuminated,
clockwise rotary field is present.
If the LCD(Left arrows) L
