Non-contact voltage test
The Testboy
®
111 is capable of detecting
wires carrying live voltages using its built-
in circuits in its tip.
If a voltage of 110 V AC or more is detect-
ed, the white cap will glow red (1a) and a
warning tone will sound.
A flowing current is not required!
Check the voltage tester before use against a known
voltage supply (e.g. a power socket) to ensure that it is
working correctly.
