as building plans and photographs taken during con-
struction, etc. before carrying out any drilling, sawing
or routing work on walls, ceilings or floors. The accur-
acy of the measuring tool may be affected by environ-
mental influences, such the level of humidity or there be-
ing other electronic devices nearby. The structure and
condition of the walls (e.g. damp, building materials con-
taining metal, electrically conductive wallpaper, insulat-
ing materials, tiles) and the number, type, size and posi-
tion of the objects may distort the measuring results.
Make sure that you are properly earthed when taking
u
measurements. If you are not properly earthed (e.g. by
wearing insulating footwear or by standing on a ladder), it
will not be possible to locate live cables.
If there are gas pipes in the building, check to ensure
u
that none of them have been damaged after complet-
ing any work on walls, ceilings or floors.
Live wires can be detected more easily when power con-
u
sumers (e.g. lamps, appliances) are connected to the
wire being sought and switched on. Switch off power
consumers and make sure that live cables are de-ener-
gised before drilling, sawing or milling into walls, ceil-
ings or floors. After performing any kind of work,
check to ensure that objects placed on the base ma-
terial are not live.
When attaching objects to dry walls, and in particular
u
when attaching them to the substructure, check to en-
sure that both the wall and the fastening materials
have a sufficient load-bearing capacity.
