SAFETY CHECK
CAUTION RISK OF ELECTRIC SHOCK
CAUTION READ THE MANUAL
Before using the tester check the condition of the batteries. This is
done by switching the tester ON.
If the BAT OK led does not light up, the battery need replacing.
Battery and fuse replacement are described later in this user's
manual..
When changing the battery, fuses, or removing the cover to access
the internal circuitry, always disconnect the test leads.
When replacing the fuse use only the type specified, 5 x 20mm,
200mA, 250V fuse, and insert correctly into the fuse holder.
Double check the switch setting, and lead connections before
making measurements.
DON'T TOUCH
Don't touch exposed wiring, connections or other "Live" parts of an
electrical circuit. If in doubt, check the circuit first for voltage before
touching it.
Do not use cracked of broken test leads.
THIS INSTRUMENT SHOULD ONLY BE USED BY A COMPETENT,
SUITABLY TRAINED PERSON.
REMEMBER
SAFETY IS NO ACCIDENT
GENERAL DESCRIPTION
This Test Instrument is a 3 Phases Presence and Rotation Indicator
combined with a 3 Phases Motor Rotation Tester.
It can be utilized on a 3 Phase Powered System (the supply side)
or on a Three Phases Unpowered Motor (the load side) without
having to worry about damage to the tester.
When utilized on a 3 Phase Powered System, the instrument is
then utilized as a 3 Phases Presence and Rotation Indicator.
When utilized on a Three Phases Unpowered Motor, the
instrument is then utilized as a 3 Phases Motor Rotation Tester.
When utilized on a 3 Phases Powered System, this instrument is a
rotary field indication instrument which display all three phases by
lighting up it's corresponding Lamp. It display the rotation
(clockwise or anti-clockwise) on a LED.
When utilized on a 3 Phases Unpowered Motor, it is also possible to
determine the motor connections U, V, W without a live circuit to
avoid subsequent damages of e.g. pumps to reversed motor rotation.
It display the rotation (clock-wyze or anti-clock-wyze) on a LED.
This instrument represents the quickest and easiest way for
servicing, repairing and electrical maintenance of 3 phase rotating
machinery.
With this equipment, you can, before connecting Load to Supply:
On the supply side;
Quickly verify the presence of the three Phases on a 3
Phases Power System.
Confirm the Phase Rotation on a Powered 3 Phase System.
On the Motor Side (Load);
Confirm the Phase Rotation on a unpowered 3 Phase Motor 3
Phases Alternator.
Confirm that each winding is connected to the terminals of the
Motor, when the rotation Leds light up.
