This instrument should only be used by a competent,
suitably trained person who understands this test
procedure fully. Personnel working with high voltage
Should be trained regularly.
2. General Description
The Non-contact high voltage detector is a new water-
proof design tool for checking the presence of AC high
voltages and low voltages.
Protection class : IP65.
The Non-contact high voltage detector consists of an
internal pickup sensor plate, a rotary switch as sensitivity
selector, a sound annunciator (high pitch, high power
buzzer) and 3 LED indicators (high bright LEDs) in a
circle for easier viewing by users in any directions. This
provides a 360° LED indication.
The Non-contact high voltage detector detects AC
voltages using the sensor plate. The sensor plate collects
part of the radiated electric field (V/M).
The electric field is seen by the internal circuitry and
triggers the input of a CMOS integrated circuit. The
integrated circuit charges a capacitor via a diode. Once
that capacitor reaches a certain level, the buzzer and the
3 LED indicators are turned on.
