OPERATING INSTRUCTIONS :
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 L1, L2, L3 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 L1, White (or yellow) to L2, Blue (or black)
to L3.
Clip the test probes to the three mains phases, L1, L2, L3
When connecting to a voltage superior to 100V AC, the
corresponding neon lamp will start to glow, indicating the presence
of the voltage on it’s corresponding lead (L1, L2, L3 lamps).

Press the TEST button to turn the instrument “ON”.
The green LED indicates that the instrument is ON and is busy
testing. The battery is OK when the green LED is ON.
Should the Green LED not come on while depressing the TEST
button, replace the battery (see Battery Replacement).
If the LED (Right arrow) L1-L2-L3 is illuminated, clockwise rotary
field is present.
If the LED (Left arrow) L1-L2-L3 is illuminated, a counter clockwise
rotary field is present.
Please note that; the phase control is displayed even if the neutral
conductor N is connected instead of L1, L2 or L3.
Also refer to table (as indicated on the back of instrument)
Determination of motor connections and rotation of motor
Connect test leads to instrument and to the motor connections.

PRINCIPLE OF HOW IT WORK :
The tester has two separate circuits :
The first circuit is the 3 Phase presence indicator, which is shown
by the neon lamps and the second circuit is the three phase
sequence indicator by LEDs.
A low battery, with a Power On indicator circuitry is also present.
3 Phase Presence Indication circuit :
This circuit uses neon lamps to indicate if a phase is present.
These neon lamps are connected in series with a limiting resistor.
Neon lamps will lights up when the voltage across any two phases
is more than 100Vac.
3 Phase sequence indicator circuit :
This circuit has an analog and a digital part. The analog signals
are amplified (so that motor rotation with very low signals can be
performed), then compared to a set of references. These results
are digitally compared to give the results on the indicating LEDs.
Switch-ON and low Battery detector :
At switch ON, the battery voltage is measured and compared. If
the battery voltage is below the threshold, the LED will not light up,
thus replacing the battery indication.
PREPARATION FOR USE :
Fuses :
In doubt, check the fuses using a ohm meter.
Please note that this instrument will not indicate anything, should
the fuses be blown.
Test Leads :
Check the test leads for defects or cracks. Replace if cracked or
damaged. Only replace with the same type.
Cleaning :
Clean the instrument case with an anti-static cleaner and wipe with
dry cloth.
REPLACING THE BATTERIES :
Prior to battery replacement always disconnect the instrument from
the circuit to which it’s connected.
Remove the test leads from the instrument.
Remove the back cover to access the battery compartment.
Remove the bad battery from the battery compartment and dispose
properly of that battery (see your local disposal facilities related to
disposal of batteries).
Only replace with a new battery of the following type :
9 V, IEC 6 LR61.
Re-insert the (battery) back cover onto the instrument and tighten
the screws.
FUSE REPLACEMENT :
Unscrew the back cover and replace the faulty fuse(s) with the
same type, then screw the cover back into place correctly.
