4.3 Single-pole Phase Test
•
The single-pole phase test starts at an AC
voltage of approx. 100V (pole > 100V
AC).
•
When using single-pole phase tests to
determine external 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 determine whether a line is
live or not. For this purpose, the double-
pole voltage test is always required.
•
Connect instrument test probe to UUT.
A signal sound indicates the phase.
4.4 Continuity Test
Make sure that UUT is not live.
Test voltage polarity at handle test probe
is positive (+).
•
Check that UUT is not live by carrying out
a doublepole voltage test.
•
Connect both test probes with UUT.
A signal sound is audible for continuity
and the LED for continuity Rx/
Ω
is illumi-
nated.
