AC Voltage Detection Procedure
For maximum sensitivity, begin by placing the detector in a
position away from live wiring.
1.
Set the selector switch to the "
AC WIRE
" position.
2.
Calibration:
Depress and hold the
TEST
button down , the detector
will begin calibration. When it sounds two beeps, the
calibration is complete. Always keep the
TEST
button
depressed throughout all the following procedures.
3. Detection:
a. Place the detector on the surface and slowly move the
unit sideways (fig 1). When the top signal LED lights
and buzzer sound continuously, stop moving, the
detector has located the edge of a live wire, mark a
spot in the groove on the walls surface (fig 2).
b.
Continue moving sideways across wall until all the
signal LEDs and the buzzer turn off, then reverse
direction and locate the opposing edge by using the
same procedure. When the LED lights and buzzer
sounds continuously stop moving and mark a spot in
the detectors groove on the walls surface (fig 3), the
midpoint between two marks is the centre of live wire.
