Measuring Process
When switching on for the first time, the measuring tool will be in the length measurement function. When switching on every subsequent time, the measuring tool will be in the measuring function that was last used.
Three settings are available for the reference level of the measurement. see Selecting the Reference Level
- Apply the measuring tool to the point at which you want to start the measurement (e.g. wall).
- If you have switched on the measuring tool with the
button, then briefly press the 
button to switch on the laser. - Press the button 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 measured value typically appears within 0.5 s and at the latest after approx. 4 s.
The duration of the measurement depends on the distance, the lighting conditions and the reflective properties of the target surface. Once the measurement process is complete, the laser beam will automatically switch off.
- The measuring tool must not be moved during a measurement (with the exception of the continuous measurement and grade measurement functions). Therefore, place the measuring tool, as far as this is possible, against or on a firm stop or supporting surface.
- The reception lens (15) and the laser beam output (16) 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.
For better visibility of the laser beam in bright extraneous light, use the laser viewing glasses (27) (accessory) and the laser target plate (26) (accessory), or shade 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)
If necessary, use the laser target plate (26) (accessory) on these surfaces.
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.
