The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m is as fol-
lows:
10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points Ⅰ and Ⅲ must therefore
amount to no more than 3 mm.
Checking the Level Accuracy of the Horizontal Line
For this check, you will need a free area of 5 × 5 m.
– Mount the measuring tool in the middle between walls A and B on the holder or a tri-
pod, or place it on a firm, flat surface. Switch on the measuring tool with the auto-
matic levelling function enabled and select horizontal mode. Allow the measuring tool
to level in.

– Align the height of the measuring tool (using the tripod or by placing objects under-
neath as required) so that the centre of the laser line exactly hits the previously
marked point Ⅱ on wall B.
– Mark the centre of the laser line on wall A as point Ⅲ (vertically above or below
point Ⅰ).

– At a distance of 2.5 m from the measur-
ing tool, mark the centre of the laser line
on both walls (point Ⅰ on wall A and
point Ⅱ on wall B).

– Set up the measuring tool at a 5 m dis-
tance and rotated by 180° and allow it to
level in.
