USING THE DETECTOR
HINTS:
Stud detection can be carried out on wallpapers but some sensitivity will be lost
depending on the thickness of the paper and in some case these can be foil backed
thus giving false reading, please confirm wallpaper types when detecting!
It is advisable to take several readings along the vertical baton or stud as a nail may
change the apparent center position.
THIS IS VERY IMPORTANT.
Because the unit will show baton or stud findings when
it is moving from thin layers to thick layers, on the contrary, the unit would not show
any signal when it is moving from thick layers to thin layers.
When the battery is low below 7V, the LowBat LED will light. Change the battery, note
the correct type, as soon as possible.
When the Detector nears the Metal, the Metal light comes on and the buzzer
sounds, scan in two different directions and make two marks. The metal is in the
middle of the two marks.(Refer Dia 6).
3. Scanning for wood in Stud Mode
Push the Mode switch in Stud mode position.
Put the Detector on the wall and press the Power button to turn on power.
Power LED then comes on. Stud LED lights for about 30 seconds and turns off.
Move the unit horizontally across the wall when the Detector nears the wood on
the back of the wall, the Stud light comes on and the buzzer sounds.
Scan in two different directions, then make two marks. The wood is in the middle
of the two marks
Note: Always keep detector flat to the surface being detected for best detection
sensitivity.
