Please carefully read through all the guidance and safety
notes in this manual before operation. If the laser distance
measure is not used in accordance with the manual provided,
it may cause damage to the device, affect the measurement
precision, or even result in serious problems.
Safety Notes
The manual should be read carefully in order to work safely
with the laser distance measure.
Never disassemble or repair the device yourself. In case of
damage, contact a local dealer or manufacturer. Do not make
any change or modification on the device. Always keep it
away from children and prevent access to the device from
unauthorised personel.
Do not focus the laser beam on persons, animals or reflective
objects. Do not stare into the direct or reflected laser beam
yourself, even not from a distance. You could blind somebody,
cause accidents, or damage your eyes.
As the electromagnetic radiation of this device may interfere
with other equipment and devices, do not use it on the plane
or near the medical equipment. Also, do not use it in
explosive or inflammable environments.
Do not discard the scrap batteries or laser distance measures
just as household garbage, please deal with them according to
the local law and regulations.
Any quality issues or questions about the device, please contact
the local dealers or manufacturer.

Press button briefly to switch the laser on, and press
again for single distance measurement.
The measured value is displayed on the main line.
MEASURING FUNCTIONS
SELF-CALIBRATION
Press button once for the length measurement;
Press button again for the width measurement.
Press button once, aprears with one of the rectangle
sides flashing on the screen.
For area measurement, please follow the instructions as
below:
Single Distance Measurement
Continuous Measurement
To ensure the measurement accuracy, please do self-calibration
regularly.
Operations: when power is off, press and simultaneously
till “CAL” appears with one number flashing under it, enter into
the self-calibration mode. Users can adjust the number with
and according to the tolerance. Adjusting range: -9~9mm.
Press button to save the result.
Area Measurement
Press button long to enter into the continuous
measurement mode. The MAX & MIN measuring values
are displayed on the auxiliary line, and the current value
is displayed on the major line.
Press button or briefly to exit the continuous
measuring mode.
The measured values of length & width are showed on the
auxiliary line.
Press button , clear off the results and remeasure if
necessary.
Press again to exit the area measurement mode.
The device can automatically process the area calculations
and show the result on the main line.
Volume Measurement
Press button twice to enter the volume measurement mode.
A flashing appears on the top of screen. For volume
measurement, please follow the below instructions:
Press once for the length measurement;
Press again for the width measurement;
Press again for the height measurement.
The device can automatically calculate the volume, and the
result is shown on the major line.
The measured values of length,width & height are shown
on the auxiliary line.
Press , clear off the results, and remeasure if necessary.
Press again to exit the volume measurement mode.
Wall Surface Measurement
In the area measurement mode, you can total up several
individual surfaces by pressing the button “add/subtract” .
If not, press button three times till aprears on the
screen.
(E.g. several walls with the same room height but different
lengths.)

When no data is shown on the Auxiliary line, you can press
to exit the wall surface measurement mode.
For more surface measurements, repeat the above operations.
Press , you can clear the previous measured results and
start the new measurement.
h
Press once to measure height A of the 1st wall;
Press again to measure length B1 of the 1st wall, and the 1st
wall surface value is shown on main line;
Press again to measure length B2 of the 2nd wall, and the
total surface value is displayed on the main line .
Pythagorean/Indirect Distance Measurement

There’re 4 pythagorean methods in case that users cannot directly
measure the distance as one obstacle would obstruct laser beam or
no target surface is available.
1. Indirect height measurement
Press button briefly four times, the indication appears
on the screen with the hypotenuse flashing.
Press , measure the length of hypotenuse (a) and angle (α).
Upon the completion of the measurement, the results of two
legs (b) and (h) are displayed on the screen.
2. Indirect hypotenuse measurement
Press button briefly five times, the indication appears
on the screen with one of the legs flashing.
Press once, measure the length of leg (a);
Press again, measure the length of leg (b);
Then the length of hypotenuse (x) is automatically shown on
the main line.

10 11
Press once, measure the length of side (a);
Press agian, measure the length of median line (b);
Press again, measure the length of side (c);
Then the length of leg(x) is showed on the main line.
Press once, measure the length of hypotenuse (a);
Press again, measure the height of side (b);
Press again, measure the length of another hypotenous (c);
Then the length of leg(X) is displayed on the main line.
4. Press button briefly seven times, appears on the screen with
one hypotenuse flashing.
NOTE:
Legs must be shorter than the hypotenuse, otherwise "err" will be
showed on the screen. To ensure the measurement accuracy, please
make sure all measurements start from the same point.
First press , "+" appears on the main line, enter into the cumulation
mode. The next measurement is added to the previous one. The last
measured value and the sum are showed on the screen.
To add/subtract the measured values, press button to select the
plus or minus function and process as your need after you get the
1st measured value.
Add/Subtract
3. Press button briefly six times, appears on the screen
with one hypotenuse flashing.
Press again , "-" appears on the major line, enter into the regressive
mode. The next measurement is subtracted from the previous one.
The last measured value and the result of final subtraction measurement
are displayed on the screen.
Pic 1 Pic 2 Pic 3
In the measuring mode, press button long for 3 secs to save
your measured results.
Memory Function
In the area, volume or pythagorean mode, you also could save
the results.
The above processes can be repeated as required. You can
switch the addition or subtraction mode by pressing the
button .
The same process can be used for adding or subtracting areas
or volumes. For example:
Adding Area Values: measure the first area as shown in Pic 1.
Then press button , and measure the second area as shown
in Pic 2, "+" appears on the left bottom. Finally, press button
to get the sum of both area values as shown on Pic 3.

Tips
Please check warning information as below:
INFO
Err
CAUSE
Out of distance measuring
range
SOLUTION
Use the device within the
measuring range
Err1 Target surface reflects too
intensely (e.g. a mirrior)
Chose the surface with
appropriate reflectance
or use a laser target plate
Err2 Target surface reflects
insufficiently (e.g. a black
fabric)
Chose the surface with
appropriate reflectance
or use a laser target plate
Err3 Low battery voltage Charge/change batteries
Err4 Out of the working
temperature range
Use the device within the
working temperature
range
Err5 Pythagorean measuring

Remeasure, ensure that
the hypotenuse is longer
than both legs
Err6 Angle sensor error Depot repair

Note: it’s recommended to use a laser target plate to increase the
measurement range in the daylight or when the target has very
poor reflection properties.
