USER MANUAL M80
14
a.
Single-pole phase test
Function of this test may not be fully achieved if the insulation condition/ grounding
conditions of user or of the equipment under test aren’t good enough. Verification of live-
circuit shouldn’t be dependent on this Single-pole phase test only, but on the voltage test.
• Hold the tester well in your hand. Connect the “L2 +” probe to the object under test.
Single pole LED lights up and buzzer sounds when a voltage of approx. 100V AC or more
exists in the object under test. (Pol≥100VAC).
7.3
Phase rotation test
•
L LED and R LED for Phase rotation test may operate on various wiring systems, 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/ grounding
conditions of user or of the equipment under test is not good enough.
7.5 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.
7.5 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. 500k
Ω) 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.
7.6 Resistance test
Make sure that object test isn’t live.
•
Switch into resistance measurement by short press of torch light. Connect both test probes
to the object under test. Resistance up to 2k show on LCD display. For resistance less than
30 Ohm buzzer sounds continuously to indicate low continuity.
•
Second short press switches into voltage measurement
7.7
Torch light
•
Pressing the torch light button will turn on the light and after approx. 30s it will turn itself off.
•
When torch light is on, pressing the torch light button for more than 6s will turn off the torch.
