4.3 Single-Pole Phase Test

To carry out single-pole phase tests ouch the contact
electrode (11) and connect instrument test probes to un-
known contact.
The single-pole phase test starts at an AC voltage of ap-
prox. 100V (pole > 100V AC).
When using single-pole phase tests to determine exter-
nal conductors the display function may be impaired
under certain conditions (e.g. for insulating body protec-
tive equipment on insulation locations).
The single-pole phase testing is not appropriate to deter-
mine whether a line is live or not. For this purpose, the
double-pole voltage test is always required.
A signal sound indicates the phase.
The LED (5) is illuminated in the display.

4.4 Voltage Test with RCD Trip Test

During voltage tests in systems equipped with RCD circuit bre-
akers, a RCD switch can be tripped at a nominal residual cur-
rent of 10mA or 30mA by measuring the voltage between L and
PE.
The RCD trips.
To avoid RCD tripping a test has to be carried out between L and
N during approx. 5s. Immediately afterwards, voltage testing
between L and PE can be carried out without RCD tripping.

4.5 Restistance Measurement (only 2000 gamma)

Make sure that UUT is not live.
Check that UUT is not live by carrying out a double-pole
voltage test.
Connect both test probes with UUT. Press Button on rear
side - for measurement point light (10) and read value
on the display.
The resistance range is 1...1999
The resistance measurement is active for 20 se-
conds after having pressed the button on the rear.
If during the resistance measurement a voltage is
present the instrument switch automatically to
voltage measurement.
