Measuring in the field
Attach the telescopic viewfinder, and
check it is engaged by applying
pressure from the side.
Free- handed aiming
(approx. 20 - 40 m):
Use target plate 563875 (DIN C6)
rsp. 723385 (DIN A4) or:
Make your own target plates of
any size:
Distance

up to 30 m

Setting viewfinder
1. With menu function "permanent"
(1.4.2) place DISTO in Continuous
mode.
2. Place indoors 5 m, 10 m or
30 m from the wall.
3. Attach alignment aid for telescopic
viewfinders to the wall as in
illustration below.

User Information
Range
In daylight (outdoors) always work
with a laser viewfinder. If necessary,
shade the target area.
Increased ranges:
At night, at dusk and when target
area is in the shade.
Reduced range:
The range of the DISTO can be
reduced by matt, green and blue
surfaces (also by trees or plants).
Rough surfaces
Rough surfaces (e.g. coarse plaster)
a mean value is indicated.
To avoid measuring to the bottom of
plaster joints: Use target plate,
3M "Post-it" or board.
Transparent surfaces
To avoid measuring errors, do not
measure towards colorless liquids
(like water) or (dust free) glass.
For materials and liquids unfamiliar
to you always take a trial
measurement.
When aiming through panes
of glass, or if there are
several ojects in the line of sight,
erroneous measurements can occur.
Wet, smooth and high-
gloss surfaces
1. Aiming at a "flat" angle deflects
the laser beam. The DISTO may
recive a signal that is too weak
(error message 255).
2. 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.
