WS-120 Wall Scanner
User Manual
Note: please read this manual carefully before using the detector and
observe safety rules and cautions in the manual; the manual shall be
subject to change without prior notice.
Applications
WS-120 is a handhold wall scanner for quick detection of magnetic metals
in wall, rooftop and floor, such as reinforcing steels, iron pipes, and
nonmagnetic metals such as aluminum pipes, copper pipes, and nonmetal
materials such as beams, PVC water pipes, as well as electrified objects
such as live wires.

Operations
Always put the detector close to the wall surface and slowly move as figure
1, sensing aperture (A) turns green and the system enters standby status;
when any object is detected, scale bar (1) shall be gradually full and
sensing aperture (A) turns red and alarm, see figure 2 for sensing scale. If
you want to find the central position, please move the detector left and right
over the hided object repeatedly and observe the scale point (2) (changes
of the scale bar and point), when the scale bar is full and central point is
displayed as figure 3, it means the central position is got.
1. ON/OFF
Short press
to turn on the detector and long press for 3s to turn it off;
After turning on, the detector initiates automatically and the scale bar
displays in full and then disappears, it enters standby status; when no any
operation on the detector in 3 minutes, the detector shall turn off
automatically.
2. AUTO Mode
The detection mode is defaulted as auto after its turn-on, you may switch to
auto mode by
key in other mode;
If more than one object are detected in auto mode, the icons displaying
sequence is live → metal → magnetic → nonmagnetic → nonmetal
3. metal mode
Short press
key to enter metal mode (for magnetic/nonmagnetic
metals)
Long press
key to enter nonmetal mode (for wood and PVC pipes)
