The single-pole phase test is only
possible when batteries are installed and
in good condition.
The single-pole phase test is not
always appropriate for testing whether
a circuit is not live. For this purpose, the
bipolar test is required.
To determine external conductors
during phase tests the display function
may be impaired (e.g. for insulating body
protection or insulating sites).
Firmly grasp the insulated grips of the
Tester probe L2 it is better for increase
the sensitivity of single-pole phase test.
