Continuous Measuring
Long press button under measuring mode and enter
into continuous measuring mode.
Maximum and Minimum measuring results display in
auxiliary display area.
Present result displays in major display area. Short press
botton or to exit continuous measuring mode.
Turn on the laser beam by short press of the button
under measuring mode, press the button again for
single measurement of length, then the measured results
displayed in the major display area.

Instruction: Power off, long press button , and then
press . Release the button , then release button
till "CAL" and a figure shows on the screen.
User can adjust the figure with button according
to the accuracy of the meter.
Adjusting range: -9 to 9mm, then, press button to
save the calibration result.

Area Measurement
Volume Measurement
The device calculates and shows the result in the major
display area.
Press , clear off the result and measuring again if
necessary.
Press again to exit the mode.
Press button twice to enter volume measurement
mode. A will shows on the top of screen. Please
follow the below instruction for volume measuring:
Press for length
Press again for width
Press thirdly for height
The resent measuring result of length is showed in the
auxiliary display area. Press , clear off the result
and measuring again if necessary.
Press once for length
Press again for width
The device calculates and shows the result in the major
display area.
Press button , shows on the screen. One of
the side of rectangle blinking on the display, please
follow the below instructions for area measuring:
Press again to exit the mode.

Pythagoras
Short press four times, when one leg of
blinking.
Press , measure the length of one leg (a)
Press , measure the length of another leg (b)
Device calculates the length of hypotenuse (x)
Short press three times to enter Pythagoras mode,
the hypotenuse of blinking.
Press , measure the length of hypotenuse (a)
Press , measure the length of one leg (b)
Device the length of another leg (x)
1. Calculate the second leg by measuring the hypotenuse
and another leg.
2. Calculate the hypotenuse by measuring the length of
two legs.
There are four Pythagoras modes in case that user gets
hard to reach the target.

Addition / Subtraction
4. Press six times till the hypotenuse of blinking
on the screen.
Press , measure the length of one hypotenuse (a)
Press , measure the length of one leg (b)
Press , measure the length of another hypotenuse(c)
Device calculates the length of the leg in full line (x)
Press , measure the length of one side (a)
Press , measure the length of the median line (b)
Press , measure the length of another side (c)
Device calculates the length of the leg in full line (x)
3. Press five times till the one side of blinking
on the screen.
Legs must short than hypotenuse, or there will be "err"
shows on screen. In order to guarantee the accuracy,
please make sure all measurements are start from the
same point.
The device can be used for length addition and
subtraction. Press to select the function once get
the length measuring result.
Short press , "+" shows in the major display area,
entering cumulation mode. Value of last measurement
and the result of cumulation will be showed on the
screen.

Do round-robin selection between continous addition
and continuous subtraction by pressing button .
Short press , "-" shows in the major display area,
entering subtraction mode. Value of last measurement
and the result of subtraction will be showed on the
screen.
Area cumulative function: Measure the first area as
showing in PIC1. Then press button , and measure
the second area as showing in PIC2, there is a "+" in the
left bottom. At last, press button to get the summation
result of these two areas which is showing in PIC3.
Not only length can be caculated in addition and
subtraction, but area and volume can do the caculation
as well. Take area as sample:
PIC1 PIC2 PIC3

Tolerance is usually affected by the distance,
reflectivity, and environment light etc. It probably
gets tolerance around ± (3mm+0.1mm/m) .
