A)

When measuring from the back edge of the measuring tool, this applies for high reflectivity of the target (e.g. a wall painted white), weak background lighting and a 20 °C operating temperature; a distance-dependent deviation of ±0.05 mm/m must additionally be factored in.

B)

When measuring from the back edge of the measuring tool, this applies for high reflectivity of the target (e.g. a wall painted white), strong background lighting, 20 °C operating temperature and high elevation. In addition, a deviation of ±0.15 mm/m must be taken into account, depending on the distance.

C)

In continuous measurement mode, the max. operating temperature is +40 °C.

D)

Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.

E)

Except battery compartment

The serial number (9) on the type plate is used to clearly identify your measuring tool.
