7.4 Trip Test of RCD / Lower impedance
voltage test
☞
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 Push-
buttons.
• The RCD should trip.
• This function is also used to lower the impedance
of the test load to clear a higher level of 'ghost' or
interference voltage.
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�) 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.
7.8 Data Hold
Under data hold mode, The LCD screen will only
show the last saved measured voltage value. There is
no auto refresh of LCD screen reading under Data
Hold mode whether the voltage tester is connected
to energized or non-energized circuit. The LED
voltage indicators will always show the actual
voltage of the circuit under measurement.
