Metal Detection Procedure
1.
Set the selector switch to the "
METAL
" position.
2. Calibration:
Hold this detector in air away from any metal object,
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. When the unit moves closer and
closer to a metallic object, the signal LEDs will light
sequentially (fig 1). When the top signal LED lights
and the buzzer sounds continuously, the unit detects
the metallic object's edge, stop moving and mark a
spot in the groove (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 metal object.
