Press the Measure –ON button [2] once for the length.
Press the Measure –ON button [2] again for the width.
Press the Measure –ON button [2] a third time for the height.
The device will show the result on the major display [f]. The current measuring result will appear in the
auxiliary display [g, h, i].
Press the Clear –OFF button [7] to remove and clear the measurement results. Press the same button
again to exit this mode.
5. Painter function
When the device is in the surface/area function, you can use the addition and subtraction function to add
up the different surface areas.
Press the Measure –ON button [2] three times till a part of the rectangular appears on the screen.
Press the Measure –ON button [2] to measure the bottom edge of the first wall. You can see the surface
measure in the major display [f].
Press the Measure –ON button [2] to measure the bottom edge of another wall. Afterwards you can get
the sum of these two walls.
Repeat these steps for more walls. Press the Clear –OFF button [7] to remove and clear the previous
measurement results. This way you can perform a new measurement.
When there is no data in the auxiliary display [g, h, i], press the Clear –OFF button [7] to exit this mode.
6. Pythagoras
This section provides 4 ways in which Pythagoras can be applied, if the user has difficulty calculating the
solution immediately.
1) Calculate the length of two legs by measuring the hypotenuse and the angle.
Press 4x on the Function –Back button [3], when the hypothenuse (a) of the triangle is blinking. Press the
Measure –ON button [2]to measure the length of the hypothenuse (a) and to calculate the angle (!)
between bevel and the bottom at the same time. The device will calculate the horizontal distance (b) and
the vertical height (h).

2) Calculate the hypotenuse by measuring the length of two legs.
Calculate the hypothenuse by measuring the length of two legs. Press the Function –Back button [3] 5x
till one leg of the triangle is blinking on the screen.
Press the Measure –ON button [2] to measure the length of one leg (a).
Press the Measure –ON button [2] again to measure the length of the other leg (b).
The device will calculate the length of hypothenuse (x).
3) Press the Function –Back button [3] six times till one side of the triangle is blinking on
the screen.
Press the Function –Back button [3] 6x till one side of the triangle is blinking on the screen.
Press the Measure –ON button [2] to measure the length of one side (a).
Press the Measure –ON button [2] again to measure the length of the median line (b).
Press the Measure –ON button [2] a third time to measure the length of another side (c).
The device will calculate the length of the length of the leg (x).
4) Press the Function –Back button [3] seven times till the hypotenuse of the triangle is
blinking on the screen.
Press the Function –Back button [3] 7x till the hypotenuse of the triangle is blinking on the screen.
Press the Measure –ON button [2] to measure the length of one hypothenuse (a).
Press the Measure –ON button [2] to measure the length of another hypothenuse (b).
Press the Measure –ON button [2] to measure the length of one leg (c).
The device will calculate the length of the leg (x).
The legs must be shorter than the hypothenuse otherwise an “err” will be shown on the screen. In order
to guarantee the accuracy, please make sure that all measurements are performed from the same starting
point.
7. Addition/ subtraction
The device can be used for length addition and subtraction.

MANUAL 202.40R –202.60G –202.80R [EN] V1.0 – 06.2022 6
Press the Addition/ Subtraction –Next button [5] to select the function once you have the length
measuring result. Press the Addition/ Subtraction –Next button [5] and a “+” will be shown in the major
display. The+ shows that the addition mode is activated. The value of the last measurement and the
result of the cumulation will be showed on the screen.
Press the Addition/ Subtraction –Next button [5] again and a “-“ shows in the major display. The –shows
that the regressive mode is activated. The value of the last measurement and the result of the cumulation
will be showed on the screen.
By pressing the Addition/ Subtraction –Next button [5], you can switch between the addition and
subtraction mode.
Not only the length can be calculated in the addition or subtraction mode, but it can also calculate the
area and volume.
An example with calculating the area:
Area cumulative function:
Measure the first area as showing in PIC1.
Then press the Addition/ Subtraction –Next button [5] and measure the second area as showing in PIC2.
A + is showing in the left bottom of the screen.
At last, press the Measure –ON button [2] to get the summation result of the two areas. This result is
showed in PIC3.
!Memory Function
Hold the Memory-Save button [8] for 3 seconds to record your measuring result. You can also record the
result in the Function indicator [b]. All those calculations can be saved by the device.
1. Read and delete the records
Press the Memory-Save button [8], then you can read the records by pressing the Function –Back button
[3] and the Addition/ Subtraction –Next button [5]. Press the Clear –OFF button [7] to delete the recent
records and hold to clear all the records. Press the Memory-Save button [8] or the Measure –ON button
[2] to exit the record mode.
When the storage is full, the screen will show a “FUL” mark.
2. Angle measurement
The angle information is displayed at the top of the screen. The angle measurement range is -90.0° to
90.0°.
!Self-calibration

This function ensures that the precision of the device is maintained.
Power off and press the Clear – OFF button [7] and the Measure – ON button [2] till “ CAL” appears. The
user can adjust the figure, that appeared on the screen, with the Function – Back button [3] or the
Addition/ Subtraction – Next button [5], according to the accuracy of the meter.
Adjusting range: -9 to 9mm, then press the Measure – ON button [2] to save the calibration result.

Note: Use a target plate to increase the measurement range during daylight or if the target has poor reflection
properties.
(*) Typical Tolerance: ±2mm, when reflectivity 100% (white surface), environment light <2000 LUX. 25°
Tolerance is usually affected by the distance, reflectivity and environment light etc. It probably gets tolerance
around ± (2mm+0.2mm/m).
§ Instrument maintenance
The meter should not be stored in high temperatures and strong humidity environments for too long. If it is not
used often, please take out the battery and place the meter in the allocated bag. Store the bag in a cool and
dry place.
Please keep the device surface clean. Use a wet soft cloth to clean dust. Never use erosion liquid for the meter
maintenance. Laser output window and its focus lens can be maintained according to maintenance
procedures for optical device.
