Checking accuracy and calibrating the target indicator
(crosshair)
Check the accuracy of the alignment of the laser and target
indicator on a regular basis.
– Select a bright area at least 10 m away with as little
illumination as possible as the target.
– Check whether the laser point is inside the target indicator
in the display.
If the laser point is not inside the target indicator, you must
recalibrate the target indicator.
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 17 onto the
quick-change plate of the tripod 27 or a commercially available
camera tripod. Tighten the measuring tool with the locking
screw of the quick-change plate.
Set the reference level for measurements with a tripod in the
basic settings or by pressing button 3 (thread reference level).
