Turn the device towards point B until the vertical beam has been displaced
by 5 m. Measure the distance E. If the distance E does not exceed 5 mm,
the accuracy is within the tolerance. In the event of significant deviations,
consult an authorised service provider (fig. 4)..

To achieve optimum results, mount the instrument on a levelling platform that is
fastened between the floor and the ceiling (e.g. clamp column).
Insert the instrument in the holder and fasten it to the levelling platform.
Then set up the instrument at a distance of roughly 5 m from a wall. Lower
the device as near as possible to the floor.

Raise the instrument towards point B until the horizontal beam has been
displaced by 2.5 m. Measure the distance E. If the distance E does not
exceed 1.25 mm, the accuracy is within the tolerance. In the event of signifi-
cant deviations, consult an authorised service provider.
