Set the mode switch to the mode for metal object, and then calibrate the tool with reference to
the method of “detecting calibration for joist”.
Notice:
1、when calibrating, the tool will automatically set the degree of induction according to the
existence of the metal object. If no metal object exists, the induction will be set to the
strongest degree; if metal object exists, the tool will automatically set to the most ideal
induction according to the type and size of the metal object.
2、When approaching or detecting the AC live wire during calibration, the caution symbol for
live wires will indicate after calibration.
2、Detection
●Joist detection---detecting joists through walls
According to the calibration requirements for joist detection, calibrate the tool to the ideal
induction degree and process as per the following steps:
11

a. Move the tool across the surface of the object in straight line horizontally and slowly, and hold
the tool firmly against the surface.
b. When the tool moves horizontally and is close to the detected object, the outer side of arrow
symbol will illumine and then slow down the moving speed, and the arrow lights of both sides
will light in turn towards the center light (if the arrow symbols of both sides go out when
moving, reset automatic calibration and detection from another place).
c. If the edge of joists are detected, the center arrow symbol will illumine and the beeps will ring,
at this time, make a mark on the edge of detected object through the marker slot by pencil. Then
continue to move the unit slowly in the same way until the arrow symbol goes out and the beeps
stop.
d. Repeat the steps above from the opposite direction to detect the other edge of the target object
and make a mark; the center of the two markers is just the center of the detected object. Repeat
the operations for several times to get the relatively precise result.
Notice: If the power button released incautiously, you must restart the calibration and repeat the steps
above to detect.
●AC live wire detection---detecting the AC live wire through walls
a. According to the calibration requirements for AC live wire detection, calibrate the tool to the
ideal induction.
b. Operate the tool and find out the two edges of AC live wires and make a mark with reference to
the method of “Joist detection---detecting joists through walls”.
c. The center of the two marks is just the center of AC live wire.
Notice: AC live wires in metal pipes or metal covered wire, as well as metal walls or walls of high
density all cannot be detected.
●Metal object detection---detecting the metal stud through walls
a. According to the calibration requirements for metal stud detection, calibrate the tool to the ideal
induction.
b. Operate the tool and find out the two edges of metal studs and make a mark with reference to the
method of “Joist detection---detecting joists through walls”.
c. The center of the two marks is just the center of metal stud.
TIPS:
1.The tool can accurately detect the center of the target object, but the width of the target object can
only be detected in a range.
2.Please do not use the tool near strong electric wave or high frequency interference.
3.Please do not use the scanner in high temperature and wet place.
12

4.Please try to avoid using the tool on wet plate and wall.

materials change a lot.
6.When tacking, cutting or drilling on the wall, ceiling or floor, please take care to the wires and
pipes on the back of them.
7.The covered wires, useless wires, telephone lines, CATV wires and circuitries without electricity
could not be detected as live wires.
8.When the thickness of detected wall is over 3/4 inches or the joists are close to each other, joist
detection is not suitable, generally, the space between joists is 16 or 24 inches, and the width of
the joist is 1-1/2 inches.
9.The detection is not suitable for metal wall or the wall with high density materials of metal.
10.When constructing beside the AC live wires, the power supply should be switched off.
11. If the tool cannot calibrate or detect normally, possible reasons are as follows:
a）When the battery is low, the “ ” symbol will blink continuously on the screen after
calibration. Replace with new battery according to instructions.
