Non-contact voltage test
The Testboy 155 is capable of detecting wires carrying live
®
voltages using its built-in circuits in its tip.
If an alternating voltage of > 110 V AC is detected, the
white cap will glow red (refer to Figure Point 1a) the
instrument will vibrate and a warning signal will sound.
To detect voltages under 110 V AC, turn the flashlight on
using the switch. The tip of the device lights up blue (1b).
Now voltages from 12 V AC can be detected. In that case
the tip lights up pink.
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.
When using the Tester, if tip does not glow, voltage could still be present. The Tester indicates
active voltage in the presence of electrostatic fields of sufficient strength generated from the
source (MAINS) voltage. If the field strength is low, the Tester may not provide indication of live
voltages. Lack of an indication occurs if the Tester is unable to sense the presence of voltage
which may be influenced by several factors including, but not limited to:
● Shielded wire/cables
● Thickness and type of insulation
● Distance from the voltage source
● Fully-isolated users that prevent an effective ground
● Receptacles in recessed sockets/ differences in socket design
● Condition of the Tester and Batteries
