– Structured surfaces (e.g. roughcast, natural stone).

If necessary, use the laser target plate (13) (accessory) on these surfaces.

Inaccurate measurements are also possible where the laser is pointed at target surfaces

diagonally.

Layers of air at different temperatures and indirectly received reflections can also influ-

ence the measured value.

Accuracy Check of the Distance Measurement

You can check the accuracy of the measuring tool as follows:

– Choose a measuring section of approx. 3–10 m in length that is permanently un-

changed, the exact length of which is known to you (e.g. room width, door opening).

The measurement should be taken under favourable conditions, i.e. the measuring

section should be indoors and the target surface for the measurement should be

smooth and reflect well.

– Measure the section ten times in succession.

The deviation of the individual measurements from the mean value must not exceed ±

4mm over the entire measuring section in favourable conditions. Record the measure-

ments in order to be able to compare the accuracy at a later date.

Errors – Causes and Corrective Measures

Cause Corrective measures

Temperature warning(b) flashes, measurement not possible

Measuring tool is outside of the operating

temperature range of -10°C to +45°C.

Wait until the measuring tool has reached

operating temperature

"Error" indicator in the display

Target surface is too reflective (e.g. mirror)

or not reflective enough (e.g. black mater-

ial), or ambient light is too bright.

Use the laser target plate(13)

The laser beam output(12) and/or recep-

tion lens(11) are fogged up (e.g. due to a

rapid temperature change).

Wipe the laser beam output(12) and/or re-

ception lens(11) dry with a soft cloth

Measurement result implausible

Target surface reflection not distinct (e.g.

water, glass).

Cover the target surface

Laser beam output(12) and/or reception

lens(11) are covered.

Keep the laser beam output(12) and/or re-

ception lens(11) clear
