I f you calibrate too closely to the object or di-
rectly on the object, the calibration can fail. If
the calibration fails, the LC display shows the
full intensity (Fig. C) and a long beeping tone
sounds or can't search any object in the wall.
Move and hold the device several centime-
ters further to the right or left of the previous
surface and recalibrate. Start the search
process.
 
R epeat several times to ensure the detection
accuracy.
 
I ncorrect measurements can occur depending
on the nature of the examined wall. Check
therefore before every measurement the posi-
tion of a known wooden or metal beam, of a
known void or a known power line. If these
are not detected by the device, the
substrate is not suitable for a search with this
device.
 
A void touching the LC display during meas-
urements as it may affect the accuracy of the
device.
 
P lease note that power lines can also be lo-
cated as metal or as beams. Always use the
additional voltage search, so that you can
exclude any incorrect interpretations.
 
P lease note that metal beams are also detected
in the Beam search „STUD" function. If you
find a beam and you want to be sure that it is
not a metal beam (or for example a water pipe),
use the additional Metal search „METAL".
 
D epending on the wall thickness and mate-
rial, it is possible that the detector may signal
a finding, before it is over the material. In this
case mark the start and end of the signalled
area at the indentation of the measuring
