Indirect distance measurement / Pythagorean measurement
- There are four modes for measuring one-sided distance in a triangle using Pythagoras' theorem. This is convenient for making indirect measurements in a complex environment.
- Indirect measurement is used to measure distances that cannot be measured directly because obstacles would obstruct the laser beam or no other target surface is available as a reflection point. Correct results are only achieved if the right angles required for correct measurement are accurately observed/measured (Pythagoras' Theorem).
1 Attention: 1 Indirect
● measurement. Depending on the application, indirect measurement has larger measurement errors than are possible with direct measurement. To improve measurement accuracy, we recommend measuring with the help of a tripod.
(2) In Pythagorean measurement, the legs of the tripod must be shorter than the counter-rectangle, or an 'Err' message will be displayed on the screen. To guarantee accuracy, please make sure that all measurements start from the same point.
Pythagorean measurement (2 points)
- Press the button (15) three times until the Pythagorean Measurement
- (2-point) icon (6) appears on the left side of the screen. One side of the triangle on the display flashes, follow the instructions below to measure the result:
- Press the button (12) to obtain the distance of the first line, change to the last direction of the object from the fixed measuring point.
- Press the button (12) again to obtain the distance of the second line. The result is displayed on the summary line.

Indirect length measurement
- Press the button (15) four times until the intermediate length icon (6) shows on the left side of the screen, the angle X is displayed in real time at the top of the screen. One side of the rectangle flashes on the display, follow the instructions to obtain the measurement result:
- Press the button (12) to obtain the angle X and the distance of the counter-rectangle, the vertical and horizontal lines. The result will be displayed in the corresponding line.

Pythagorean measurement "1"

The device can be used to add and subtract measurements taken.
- Press buttons (13) (14) to select the function, pressing once will give you the measurement result.
- Briefly pressing button (13) ((14)), "+" ("-") will cause the screen with the addition or subtraction mode to appear. The screen will also show the previous set of measurements and the possible actions to select "+" ("-").
• The screen will display 0.000 if there is no set of measurements. - Area and volume can also be added up and subtracted. Take this area as an example:
Surface addition function:
Step 1: Measure the first area as shown in PIC1.
Step 2: Then press the button (13) a "+" will appear in the lower left corner of the screen, measure the second area as shown on PIC2.

RECORDING FUNCTION
- Storage function: the storage function will be activated when the tool is running. The data of each measurement group will be automatically saved to the database and the maximum number of measurement groups is 30.
- Data groups will be sequenced from 1 to 30 until 30 groups are reached.
- When the database has fully stored 30 data groups and the 31st data group is measured, the data from the first group will be deleted automatically. The remaining data groups will be moved forward 1 place and the 31st data group will be stored in place 30. Replacing the battery will not result in data loss and the data will be stored as at the last shutdown.
- Opening the database: press the button (15) briefly until the icon (9) appears, the database will be accessible. The latest measured data will be displayed by default.
- Scrolling up and down the database: short press on the button (13) to scroll up the data; short press on the button (14) to scroll down the data.
- Deleting a group of measurements: briefly pressing the button (16) deletes the data. The last group of data will be deleted.
General information
The receiving lens and the laser beam outlet located on the left side of the device must not be covered during measurement. Do not move the device during measurement (except in continuous measurement mode). Therefore place the measuring instrument, if possible, on a stable, level and non-slippery surface.
Factors influencing the measuring range
The measuring range depends on the lighting conditions and the reflective properties of the target surface. To improve the visibility of the laser beam when working outdoors and when sunlight is intense, shade the target surface.
Factors influencing measurement accuracy
Due to physical effects, erroneous measurements cannot be ruled out when measuring on different surfaces such as:
• Transparent surfaces (e.g. glass, water),
• Reflective surfaces (e.g. polished metal, glass),
- Porous surfaces (e.g. insulation materials),- Structured surfaces (e.g. plaster, natural stone). In addition, erroneous measurements are also possible if the target surfaces are inclined.
Also, air layers of different temperatures or indirectly received reflections can affect the accuracy of the measurement taken.
Control of distance measurement accuracy
The accuracy of the measuring tool can be checked as follows:
- Choose a measurement distance that does not vary between approximately 3 and 10 m (9.8 to 32 ft) in length and whose dimension is known exactly (e.g. length of room, width of doorway).
- The measurement should be carried out under the most favourable conditions, i.e. the measuring section should be in a room with poor lighting and the target measurement area should be a smooth, well-reflecting surface (e.g. a wall painted white).
• Measure the distance 10 times in a row.
The deviation of individual measurements from the average value must not exceed ±2 mm ( ±0.12 in) of the entire measuring distance. The measurements should be recorded so that the accuracy can be compared in later measurements.
Working with a tripod
The use of a tripod is particularly necessary when measuring longer distances. The measuring device has a 1/4" thread for mounting on the tripod. Use the 1/4" fixing screw to mount and tighten the measuring device to the tripod.
Set the appropriate reference level for the tripod measurement by pressing the button (13).
