Measuring with the Positioning Pin
(see figures B, C, F and G)
The positioning pin 18 is suitable for measuring
out of corners (diagonal within a space) or from
hard to reach areas, such as from roller-shutter
rails.
Press on the positioning pin latch 1 to fold it in
or out, or change its position.
For measurements starting from outer corners,
fold the positioning pin aside; for measurements
from the rear edge of the positioning pin on, fold
it out to the rear.
For measurements with the positioning pin, ad-
just the reference plane accordingly by pressing
button 8 (for measurements with the position-
ing pin aside, set to measuring from the rear
edge of the measuring tool).
Aligning with the Spirit Level
The spirit level 14 allows for simple levelling of
the measuring tool. This allows for easier sight-
ing of target surfaces, especially over longer
distances.
In combination with the laser beam, the spirit
level 14 is not suitable for levelling.
Sighting with the Optical Sight (GLM 250 VF)
(see figure N)
The sighting line through the optical sight and
the laser beam run parallel to each other. This
allows for precise sighting over long distances,
when the laser dot is no longer visible with the
naked eye.
For sighting, view through the viewfinder of the
optical sight 10. Take care that the optical sight
window 25 is not obstructed and clean.
Note: For close vicinities, the actual and the
displayed target point are not identical.
Sighting with the Alingment Aid (see figure O)
The alignment aid 24 supports sighting over
larger distances. For this, view alongside the
alignment aid on the side of the measuring tool.
The laser beam runs parallel to this sighting line.

Working with the Tripod (Accessory)
The use of a tripod is particularly necessary for
larger distances. Position the measuring tool
with the 1/4" thread 21 onto the quick-change
plate of the tripod 30 or a commercially available
camera tripod. Tighten the measuring tool with
the locking screw of the quick-change plate.
Set the corresponding reference level for meas-
urement with a tripod by pushing button 8 (the
reference level is the thread).
