· Volume Measurement
1. Click twice, to enable Volume measurement.
2. Follow the instructions on main screen to measure width, length and
height. The result will show on screen.
3. You can click or to Addition/Subtraction volume.
· Area Measurement
1. Click one time, to enable Area measurement.
2. Follow the instructions on main screen to measure width and length.
The result will show on screen.
3. Click or Addition/Subtraction area.
1. There are 8 units inside the laser distance meter.You can change Unit
immediately [m -> 10/33m]
3. In the anytime, tap and hold 2 second later, can change the unit, the data
on the screen is also automatically converted. After the screen is displayed in
the unit you wish to use, release the button.
1. After measure, click or , the data of measurement can be set to be
added or subtracted.
2. In this case, the second measurement (Add/Sub) can be performed. The
machine will automatically calculate the pen distance and the distance of the
previous pen and display the result and the process on the screen.
1. Continuous Measurement is also called tracking measurement and is
recommend to use for seeking proper distance.
2. Tap and hold 2 second later, it will start continuous measurement mode.
3. Let laser dot to target to start measure, click or can stop continuous
measurement, click again can exit continuous measurement mode.
1. If laser dot didn’t appear, click to open laser dot.
2. If laser dot appear, keep your position stable and click can start measure.
3. The distance will show on the screen. If you need to measure again, repeat step 1.
1. Click the or to turn on the device.
2. Get ready to measure by turn on the laser dot after the device open.

· First mode is Indirectly Height I
1. Click once, enter the first mode of Indirectly Height I.
2. Follow the instructions on the main screen to measure the length of hypotenuse(s)
and base to get the result of height.
· Second mode is Indirectly Height II, you can get the total height
1. Click twice, enter the second mode of Indirectly Height II.
2. Follow the instructions on the main screen to measure the length of hypotenuse 1,
the length of hypotenuse 2 and base to get the result of height.
· Third mode is Indirectly Height III ,you can get the altitude height
1. Click three times, enter the third mode of Indirectly Height III.
2. Follow the instructions on the main screen to measure the length of hypotenuse 1,
the length of hypotenuse 2 and base to get the result of altitude height.
· Fourth mode is an application of the advanced Pythagorean
theorem, which measures the height difference through the
angle change of the instrument.
1. Click four times, enter the fourth mode of Indirectly Height IV.
2. follow the instructions on the main screen to measure the length of hypotenuse 1,
you will get the result of height and angle.
· Fifth mode is the use of the advanced Pythagorean theorem to
measure the sum of the heights of the two hypotenuses.
1. Click five times, enter the fourth mode of Indirectly Height V.
2. Follow the instructions on the main screen to measure the length of hypotenuse 1
and the length of hypotenuse 2 you will get the result of height and angle.
· Sixth mode is the application of the advanced Bishop's theorem.
It can measure the height difference between two oblique sides.
1. Click six times, enter the fourth mode of Indirectly Height VI.
2. Follow the instructions on the main screen to measure the length of hypotenuse 1
and the length of hypotenuse 2 you will get the result of altitude height and angle.
