Properly hold the instrument close to the area to be tested. If found
the wired wire, live icon and the received signal strength will appear
on the display. When the sound is turned on, the "AC" will be
broadcast followed by a "di" sound; there must be more detect the
change location back and forth in order to determine the location of
the live wire. The closer the instrument is to the live wire, the
stronger the signal and the more rapid of the sound.
4. Wooden wall detection mode
In the non-wood wall detection mode, short press the
to enter
the wooden wall detection mode; the wooden wall detection mode is
mainly used to detect the uniformity of the wood wall, such as
identifying hidden rib and slot position. There are two operation
modes for wooden wall detection: Automatic calibration detection
mode and Manual calibration detection mode.
Automatic calibration detection mode
Step 1: Place the instrument close to the target surface to be detected
according to the hand-held schematic diagram, and the instrument will
perform automatic calibration. After the calibration of the instrument is
completed, move the instrument slowly in the area to be measured.
When the material change or others such as rib or slot position is
detected, The screen displays information such as "RIB" or "SLOT"
and the strength of the received signal. When the sound is turned on,
the instrument will emit a "didi" sound after broadcasting "RIB" or
"SLOT". when the sensing area of the instrument is closer to rib or slot
position and material changes or others. The stronger the sound, the
faster the "Didi" sound.
Step 2: Center judgment, Move the instrument slowly, when the
signal reaches a certain intensity, it means it has reached the target
center position, and the center mark of the screen lights up.
Step 3: Lift the instrument to terminate the scanning detection and
enter the interface to be calibrated. Close to the surface of the
detected target again, recalibration and detection can be performed.

Manual calibration detection mode
Enter the wooden wall detection mode, the default is the automatic
calibration detection mode. After close to the surface of the detected
target, if the color of the detected target surface is dark and cannot
be calibrated, short press the
to enter the manual calibration
detection mode to force the instrument to calibrate. After the
calibration is completed, slowly move the instrument in the area to
be measured and scanning detection. In the manual calibration
detection mode, short press the
again to exit and return to the
automatic calibration detection mode.
Note: 1. The principle of wooden wall detection is to distinguish the uniformity of
the material between the calibration location area and other detection
areas, which is presented in the form of rib and slot position, that is, solid
and hollow.
2. If presses the "wood " to enter the manual calibration detection mode
process, the hand leaves the sensing area of the instrument quickly.
5. System setting
Short press
to enter the system setting interface, the system
setting interface can set the detection sensitivity of the instrument,
calibrate the metal detection mode and view the signal version
information of the instrument.
Set sensitivity
Short press
to select the sensitivity setting, short press
to enter the sensitivity setting interface, you can set the sensitivity of
the three detection modes separately, in the sensitivity setting
interface, short press the
to select the setting item, short press
to adjust the sensitivity, short press
to return.
Metal detection mode calibration
Large-scale changes in the temperature or humidity of the
environment where the instrument is located will cause false alarms
in metal detection or shorten the detection depth.。

Short press
to select metal detection mode calibration,
short press
to enter the calibration interface, short press
to
start calibration, and short press
to exit the calibration interface
after the calibration is completed.
Note: When calibrating, please make sure that there is no interference of metal
and strong magnetic field around(such as lifting in the air) press the
to
calibration. If the calibration process fails, please recalibrate.

Short press
to select About , short press
to enter, and
then you can view the instrument model, software version, and
hardware version information on this interface. Short press
