OPERATION
CAUTION. Live wires may not be
detected if wires are shielded or in
conduits or behind thick walls or are
more than 40mm away from the scanned surface,
or in concrete, behind a plywood shear wall or
metallic wall covering, or if moisture is present in
the environment or on scanned surface or on the
sensor.
Prior to operating this tool, make sure the area
marked “SENSOR” in the bottom of the housing is
dry. If required, wipe dry using a dry and clean
cloth.
Environmental influences, such as humidity or
closeness to electrical devices, can influence the
measurement accuracy. Surface quality and
condition of the walls (e.g., moisture, metallic
building materials, conductive wallpaper, insulation
materials and tiles) as well as the amount, type,
size and position of the objects can lead to
inaccurate measurements.
If the tool has been subjected to an extreme
temperature change, allow the sensor to adjust to
the ambient temperature before use.
Due to uneven density of tile work on cement board
(used in kitchens, bath/wash rooms) wall sensor
may generate false indications.
Do not expose product to rain or wet conditions or
long term exposure to the sun.
Do not use in harsh environment. Use only in
temperature range -10C° - + 50C°.
To increase battery life, turn off the sensor after
each use.
TURNING THE UNIT ON AND OFF
Press and hold the On/Off button to turn on the
unit, Fig.2. Release the On/Off button to turn the
unit off.
CALIBRATING THE WALL DETECTOR
Hfld the wall detector in your hand away from any
metal objects and live wires. Quickly press the
On/Off button several times unti the metal
detection indicator light and the live wire detection
indicator light illuminate red, Fig.3. When the lights
go out the machine is ready to use.
Note: If the instrument fails to calibrate it could be
due to:
The current measured surface is too wet.
Environmental influences, such as humidity.
Instrument malfunction.
MEASUREMENT OPERATION
With the wall detector flat against the wall and the
On/Off button pressed move the instrument left or
right. When the instrument detects a metal edge,
the metal detection indicator light will change from
green to red and a beep will be heard. Mark this
point with a pencil using the marker point on the
top of the wall detector, Fig.4
