Bosch PDO 6 Operating Instructions Manual page 16

"Live" wires/conductors can be detected easier when power con-
sumers (e.g., lamps, appliances) are connected to the wire/conduc-
tor being sought and switched on. Wires/conductors with 110 V,
230 V and 400 V (three-phase current) are detected with about the
same scan capacity.
Under certain conditions (such as when behind metal surfaces or
behind surfaces with high water content), "live" wires/conductors
cannot be detected with certainty. When measuring indicator c is
indicated over a larger range, then the material is screening-off elec-
trically and the scan for "live" wires/conductors is not reliable.
Operating Instructions
On condition of the principle, the measuring values can
be impaired through certain ambient conditions. These
include, e.g., the proximity of other equipment that pro-
duce strong magnetic or electromagnetic fields, moisture,
metallic building materials, foil-laminated insulation
materials or conductive wallpaper. Therefore, please also
observe other information sources (e.g. construction plans)
before drilling, sawing or routing into walls, ceilings or floors.
Marking Objects
Detected objects can be marked as required. Where the amplitude of
measuring indication c is at its maximum, the centre of the object is
located below marking hole 2. The limits of an object are indicated by
the colour change of the illuminated ring 1 from green to red. Using a
pen, mark the sought after location through the marking hole 2.
"AutoCal" Calibration Indicator
When the check mark behind the "AutoCal" calibration indicator d
flashes for longer periods or if it is not displayed anymore, reliable
scanning is no longer possible. In this case, send in the measuring
tool to an authorised Bosch after-sales service agent.
