INSTRUCTION MANUAL
Phase rotation test
•
L LED and R LED for Phase rotation test may operate on various wiring sys-
tems, but effective testing result can be obtained only on three-phase 4-wire
system.
•
Hold the tester good in your hand and connect both probes to the object under
the test.
•
Phase-to-phase voltage is indicated by voltage LEDs.
•
R LED lights up for right rotary field.
•
L LED lights up for left rotary field.
•
Measurement principle: The instrument detects the phase rising order regarding
the user as earth.
Function of this test may not be fully achieved if the insulation condition/ groun-
ding conditions of user or of the equipment under test is not good enough.
Trip test of RCD
For voltage tests in systems with RCD (earth leakage circuit breakers) an RCD
can be tripped with a 10mA or 30mA nominal leakage current on single phase
AC 230V power system.
•
Connect probes "L1" and "L2" between L and PE of RCD protected system.
•
Press simultaneously both of trip TEST RCD pushbuttons.
•
The RCD should trip.
Continuity test (Rx) / Diode test
The test circuit/object shall be de-energized before measurement.
•
Check for the absence of voltage by conducting a two pole voltage test on the
test object.
•
Connect both test probes together or press the torch light pushbutton to switch
ON the tester.
•
Connect both test probes to the test object. For continuity (up to approx.
500 kΩ) the continuity test LED – Rx is on and the buzzer is active.
•
Continuity test automatically switches OFF after approx. 30 seconds if no
continuity is detected. When tester is OFF, If continuity is detected it will be
automatically switched on again.
Torch light
•
Pressing the torch light button will turn on the light and after approx. 30 s it will
turn itself off.
•
When torch light is on, pressing the torch light button for more than 6 s will turn
off the torch
Battery replacement
Remove the probes from any testing point, when opening the battery case.
Batteries are empty when the continuity test with both test probes connected
cannot be done anymore. A battery symbol in the LCD indicates low battery.
Follow the procedure below and replace batteries with new ones (type
IEC LR03 1.5 V).
•
Unscrew the battery door using Philips type screwdriver.
•
Pull out the battery door and replace the batteries. Insert new batteries accor-
ding to the engraving on the battery door.
•
Re-assemble battery door.
Confirm that the battery door case is properly locked prior to measurements.
