90° Vertical Beam Accuracy
You will need at least 1,5 m
1. Place the laser unit (without its mounting
bracket) on a level floor, and turn on all
beams (mode 4).
2. Measure exactly 0,91 m (3 ft) out from the
center of the laser unit along the vertical
beam of the laser cross. To easily refer-
ence the center of the laser unit start the
first measurement against the outer base
of the laser unit, measure out 0,91 m (3 ft),
and then subtract 4,3 cm (1,69 in). Mark
this point P

3. Measure exactly 1,22 m (4 ft) out from the
center of the instrument along the at 90°
vertical reference beam, and mark this
point P .
