are several objects in the line-of-sight erroneous measure-
ments can occur.
Wet, smooth or high-gloss surfaces
1 Aiming at a "Acute" angle deflects the laser beam.
The DISTO may receive a signal that is too weak
(error message 255).
2 If aiming at a right angle, the DISTO may receive a
signal that is too strong (error message 256).
Inclined, round surfaces
Can be measured with the laser.
Requirement: There is enough area on the target surface
for the laser spot.
Free-handed aiming
(approx. 20 - 40 m):
Use target plate 563875 (DIN C6) rsp. 723385 (DIN A4).

White surface: to 30 m
• Brown surface: from 30 m on
In the field

viewfinder (2x magnification).
With measurements from a distance of 25 m the laser spot
is in the centre of the crosshairs. Below a distance of 25 m
the laser spot moves to the edge of the crosshairs.
