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.
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.
6.2. AC live wire detection detecting the AC live wire through walls
According to the calibration requirements for AC live wire detection, calibrate the tool to the ideal induction.
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”. 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.
6.3. Metal object detection detecting the metal stud through walls
According to the calibration requirements for metal stud detection, calibrate the tool to the ideal induction.
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”. The center of the two marks is just the center of metal stud.
6.4. Tips
• 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.
• Please do not use the tool near strong electric wave or high frequency interference.
• Please do not use the scanner in high temperature and wet place.
• Please try to avoid using the tool on wet plate and wall.
• Sometimes, the scanner cannot detect the slate or mixed plate correctly because the density of the materials
change a lot.
• When tacking, cutting or drilling on the wall, ceiling or floor, please take care to the wires and pipes on the
back of them.
• The covered wires, useless wires, telephone lines, CATV wires and circuitries without electricity could not
be detected as live wires.
• When the thickness of detected wall is over 2cm or the joists are close to each other, joist detection is not
suitable, generally, the space between joists is 40 or 60cm, and the width of the joist is 3,8 cm.
• The detection is not suitable for metal wall or the wall with high density materials of metal.
• When constructing beside the AC live wires, the power supply should be switched off.
