Non-contact voltage test
No test leads need to be attached (as
show in Figure 2)!
The circuitry located in the back of the
®
Testboy 20 Plus can detect live-
voltage wires with voltages greater
than >110 V AC.
A flowing current is not required! The
metal clip acts here as an extended
sensor.
It is not dangerous to touch this metal
clip!
Single-pole phase searching
Plug a test lead in the COM port (as
shown in Figure 3).
Then touch the probe tip to the wire.
Be sure not to touch the clip attached
to the back side (move to up position).
If a phase is active, the rote V~ LED
will illuminate!
The sensitivity of the electronics in-
creases if the metal clip is contacted
during the measurement. This means
that AC voltage fields can be detected
even at distances of several millime-
tres!
It is not dangerous to touch this metal
clip!
