Measuring Process
Once switched on, the measuring tool is in the length measurement function.
Once the measuring tool has been switched on, the rear edge of the measuring tool is selected as the reference level for measurement. You can change the reference level. see Selecting the Reference Level
- Apply the measuring tool to the point at which you want to start the measurement (e.g. wall).
- Briefly press the
button to switch on the laser. - Aim the laser point at the target.
- Press the button again to start the measurement.
Once the measurement process is complete, the laser beam will switch off. For a further measurement, repeat this process.
Measured values or end results can be added or subtracted.
The duration of the measurement depends on the distance, the lighting conditions and the reflective properties of the target surface. Upon completion of the measurement, the laser beam will automatically switch off.
In the continuous measurement function, the measurement begins immediately after the first press of the button.
If there is no measurement approx. 20 s after targeting, the laser beam will automatically switch off to preserve the non-rechargeable batteries.
- The measuring tool must not be moved during a measurement (with the exception of the continuous measurement function). Therefore, place the measuring tool, as far as this is possible, against or on a firm stop or supporting surface.
- The reception lens (12) and the laser beam output (13) must not be covered during the measuring process.
Influences on the Measuring Range
The measuring range depends on the lighting conditions and the reflective properties of the target surface.
Influences on the Measurement Result
Due to physical effects, incorrect measurements are possible when measuring on various surfaces. These include:
- Transparent surfaces (e.g. glass, water)
- Reflective surfaces (e.g. polished metal, glass)
- Porous surfaces (e.g. insulation materials)
- Structured surfaces (e.g. roughcast, natural stone)
To help with targeting, use an object that is as lightly coloured as possible (e.g. a sheet of bright white paper).
Incorrect measurements are also possible on slanted target surfaces.
Likewise, layers of air with different temperatures or indirectly received reflections can influence the measured value.
