Under off status, press button , device and
laser get starting simultaneously and stand by for
measurement.
Under on status, long press button for 3 seconds
to turn the device off. The device can also be shut
off without any operation for 150 seconds.
Unit setting
Press button , reset current measurement unit,
the default unit is: 0.000m
Backlight Setting
Press button , turn the backlight on or off
There are 6 units for selection
Self-Calibration
This function can keep the precision of the device.
Instruction: Power off, Long press button , and
then press , release the button till "CAL"
and a figure under it display on the screen. User can
adjust the figure with button and according to
the accuracy of the meter. Adjusting range: -9 to 9mm.
length area volume
Reference Point
Press key to change the reference point. There
are four reference points: top, screw, bottom and
the end piece.
Long press button under measuring mode and
enter into continuous measuring mode. Maximum
and Minimum value show on the LCD.
Length Measurement & Calculation
Single Distance Measurement:
Turn on the laser beam by short press of the button
under measring mode; Press the button
again for single measurement of length,then the
measured results displayed in the major display
area.
Continuous Measurement:
Present result displays in major display area. Short
press botton to exit continuous measuring
mode.
Press button , shows on the screen. One
of the side of rectangle blinking on the display,
please follow the below instructions for area
measuring:
Area Measurement:
Press once for length
Press again for width
The device calculates and shows the result in the
major display area.
Press , clear off the result and measuring again
if necessary
2. Calculate the hypotenuse by measuring the
length of two legs.Shor press twice, when one
leg of blinking,
Press , measure the length of one leg (a)
Press , measure the length of another leg (b)
1. Calculate the second leg by measuring the
hypotenuse and another leg.Short press to
enter Pythagoras mode, the hypotenuse of
blinking.
Press , measure the length of hypotenuse (a)
Press , measure the length of one leg (b)
Device calculates the length of another leg (x)
Volume Measurement
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 device calculates and shows the result in the
major display area.
Press , clear off the result and measuring again
if necessary.
Pythagorean Measurement
There are four Pythagoras modes in case that user
gets difficults to reach the target. Please press button
to select the mode.
4. Press four times till one hypotenuse of
blinking on the screen.
Press , measure the length of one hypotenuse (a)
Press , measure the length of another hypotenuse (b)
Press , measure the length of one leg (c)
Device calculates the length of the leg in full line (x)
3. Press three times till the one hypotenuse of
blinking on the screen.
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)
Device calculates the length of hypotenuse (x)
then press ; Measure the second area, get PIC 2,
there is a "+" on the left corner of the screen; At last,
press get the addition result as PIC 3.
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.
Addition / subtraction
The device can be used for length addition and
subtraction.
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.
Press , "-" shows in the major display area,
entering regressive mode. Value of last measurement
and the result of difference will be showed on the
screen.
Not only distance but also area and volume can be
added or substracted. For example:
Area Addition: Measure the first area, get PIC 1,
PIC 1 PIC 2 PIC 3
Area Sustraction:The same steps as above.
