Detection of Electrical Wiring
Issue Possible Reason Remedy
Area of voltage appears
much larger than actual
electrical wire.
• Static charge may be
present on drywall,
spreading voltage as
much as 12 inches (305
mm) on either side of an
actual electrical wire.
• It may help to put the other hand
on the wall and measure again.
• Turn unit off then back on again at
edge of where voltage was first
detected and scan once more.
• Shut off the appropriate building
circuit and restart scan. If
searching for electrical wiring, use
metal mode to search for metal
objects that might be wiring.
Electrical wiring is not
detected in area where it is
thought to be.
• Wires may not be live (hot)
• Wires may be inside of
metal wall covering.
• Wires may be too deep.
(See Maximum Scanning
Depth, page 4.)
• Make sure that circuit has power;
make sure that power switches
are turned on.
• Try plugging in a lamp into outlet
and turning on switch to increase
current and chance of detection.
• Use metal scan to check for
detection of metal.
RECALIBRATION
If the main measuring indicator f continuously
shows an amplitude even though there is no
metal object in the vicinity of the multi-
detector, the multi-detector can be calibrated
manually:
1. Remove all objects in the vicinity of the
multi-detector (including wrist watches or
rings of metal) and hold the multi-detector
up in the air.
2. With the multi-detector switched off, press
both the “on/off” button 7 and the wood-
detection mode button
5 until the
illuminated ring
1 lights up red and green at
the same time. Then release both buttons.
When the calibration process is successful,
the multi-detector will start over after a few
seconds and is then ready for operation.
MAINTENANCE AND CLEANING
• Protect multi-detector against moisture and
direct sunlight.
• Wipe away debris or contamination with a
dry, soft cloth. Do not use cleaning agents or
solvents.
• In order not to affect the measuring ability of
the multi-detector, decals/stickers or name
plates, especially metal ones, may not be
attached in the sensor area
9 on the front or
back side of the multi-detector.
• Do not remove the felt pads
8 on the back
side of the multi-detector. Replace the felt
pads when they are damaged or used. For
this, completely remove the felt pads and
glue the new felt pads onto the same spots.
• Store and transport the multi-detector only in
the supplied protective case.
• In all correspondence and spare parts
orders, please always include the 10-digit
article number given on the type plate of the
multi-detector.
“AutoCal” CALIBRATION INDICATOR
When the check mark behind the “AutoCal”
calibration indicator g flashes over a longer
period or if it is not displayed anymore (other
than when the
“ZOOM” button 4 has been
pressed down in the wood-detection mode),
reliable scanning is no longer possible.
