5. Calibration
5.1.
The tool should be calibrated on the surface of the detected object before detecting or after function “D” switch’s
diversion.

5.2. Detecting calibration for joist
Set the mode switch to the mode for joist, and then lightly adhere the scanner to the detected surface, press
the power button to connect to the power supply, the scanner will send out sound indication and be calibrated
automatically according to the thickness of the detected wall. The calibration is finished when the sound stops.
You can process joist detection now and please always press the power button during the detecting course.
Notice
• when calibrating, the scanner cannot be directly put on the materials with high density (e.g. metals, joists), or
wet, new-painted and unsuitable places. Restart calibration by changing another place.
• When approaching or detecting the AC live wire during calibration, the caution symbol for live wires will
indicate after calibration.
5.3. Detecting calibration for AC live wires
Set the mode switch to the mode for AC live wire, and then calibrate the tool with reference to the method of
“detecting calibration for joist”.
Notice
When calibrating, the tool will automatically set the degree of induction according to the distance to the live
wire. If distance to the AC live wire is far enough, the induction will be set to the strongest degree; if close to
the AC live wire, the tool will automatically set to the most ideal induction according to the distance.
5.4. Detecting calibration for metal objects
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
• 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.
• when approaching or detecting the AC live wire during calibration, the caution symbol for live wires will
indicate after calibration.
6. Detection
6.1. 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: Move the tool across the surface of the object in straight line horizontally
and slowly, and hold the tool firmly against the surface.
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).

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.

7. Laser marking function
7.1.
Press the K button to the ”LASER” location, the tool will enter laser marking function. The laser diode is
powered and emit laser line.
7.2. Tool fixation
When using the tool on the dry wall or wooden wall, you can locate the tool by push pins fixation function:
• Locate the tool on the desired place.
• Push inward and keep pressing the protect buckle on the side of the push button , making the buckle claw
break away from the joint surface.
• Press the push pin button N emphatically. Forelock the push pin into the wall and make sure the fixation is
firm.
Notice
• Please don’t press the push pin without breaking protect buckle away from the joint surface to avoid damage
to the tool.
• When the push pin is not needed, please pull the pin back to make sure the push pin protect buckle has been
retracted to original place to avoid damage
7.3. Laser mark
• Take measurement and determine where the laser line needs to be projected.
• Measure for position of laser line. (See “How to fix the tool”)
• Determine laser orientation.( Do not stare into the laser beam. See ”Safety Instructions”):
a. Horizontal line: turn the tool (left or right) until the bubble above the tool is between the two lines.
b. It can project laser line at an angle by rotating the tool and using hanging hole assistant location instrument.
• Length of light adjustment: When projecting laser line, you can open the support board on the back of the
tool or place some object to underlay the whole tool to obtain suitable length of the laser line.
