1.4.3 Vertical accuracy check
As reference, use a plumb-bob and attach it as close as
possible to an approx. 3 m high wall.
Position the instrument at a distance of approx. 1.5 m
from the wall at an elevation of approx. 1.5 m.
Direct the instrument at the wall and switch on. Rotate
the instrument and align it with the bottom of the plumb
line. Now read off the maximum deviation of the laser
line from the top of the plumb line. If the difference does
not exceed 3 mm your Prexiso XL2 is within spec.
