Checking Plumb Accuracy
For this check, you will need a clear measuring space on firm
ground with a distance of approx. 8 ft (2.5 m) between the floor
and the ceiling.
– Place the measuring tool on the floor. Switch the measuring
tool on and rotate it on the magnetic rotating mount (3) in
such a manner that the bottom laser point can be seen on the
floor. Allow the measuring tool to level in.
8 ft
(2.5 m)
– Mark the centre of the top laser point on the ceiling (point I).
Also mark the centre of the bottom laser point on the floor
(point II).
