thermal insulation) or in an empty metal pipe, the signal will not reach the measuring
tool and you will not be able to find the cable.
– The measuring tool must be sufficiently earthed. To do this, hold it firmly (without
gloves) by the gripping surface (9). Make sure that you are in good contact with the
floor. Insulating shoes, ladders or platforms may compromise your contact with the
floor. The floor must also be earthed in order for live cables to be detected.
– The 50–60 Hz signal from the electricity cable must be stronger along the cable
than in its immediate vicinity. If the wall is very dry or poorly earthed, the signal will
be the same strength throughout the wall. This will result in the measuring tool indic-
ating that it has found a signal over a large area, but it will not be able to detect the ex-
act location of the cable. In this instance, it may be helpful to place your free hand on
the wall 20−30 cm from the measuring tool in order to conduct the signal away from
the wall.
If you are unable to detect the cable in <Current> operating mode, then you may be able
to search for it as a metal object in <Metal> operating mode. Please be aware that the
maximum detection depth is low (approximately 2−3 cm). While solid-wire cables can be
detected in <Metal> operating mode, stranded-wire cables cannot.
Multi-phase (known as three-phase current or heavy current) electricity cables cannot be
detected in <Current> operating mode because the signals from the different phases
cancel each other out. You can, however, detect multi-phase electricity cables as metal
objects in <Metal> operating mode. The maximum detection depth is somewhat higher
than that for single-phase electricity cables.
<Settings> menu
To open the <Settings> menu, lift the measuring tool off the substrate and
press the button with the symbol shown opposite.
The sound and language settings will remain the same unless changed (i.e. they do not
need to be set every time you switch on the tool).
Submenu <Sound>:
You can switch the sound indicating that an object has been found on and off. The selec-
ted setting appears with the symbol (e) in the status bar.
Submenu <Language>:
Select the language of the menu navigation.
Submenu <Reset>:
Here you can recalibrate the measuring tool manually. It is advisable to recalibrate the
measuring tool if it starts to continuously detect a metal object without there actually be-
ing one nearby.
