A)

When measuring from the front 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 front edge of the measuring tool, this applies for high reflectivity of the target (e.g. a wall painted white), strong background lighting, a 20 °C operating temperature and high elevation; a distance-dependent deviation of ±0.15 mm/m must additionally be factored in.

C)

At an operating temperature of 25 °C

D)

After user calibration at 0° and 90°; An additional grade error of ±0.01°/degree to 45° (max.) has to be taken into account. The left-hand side of the measuring tool serves as the reference level for grade measurement.

E)

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

F)

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