– The discrepancy d between the two marked points Ⅰ and Ⅲ on wall A reveals the ac-
tual horizontal deviation of the measuring tool.
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 Vertical Line
For this check, you will need a door opening (on solid ground) which has at least 2.5 m of
space either side of the door.
– Place the measuring tool 2.5 m away from the door opening on a firm, flat surface (not
on a tripod). Switch on the measuring tool in the mode with automatic levelling. Se-
lect vertical mode and allow the measuring tool to level in.

– Mark the centre of the vertical laser line
on the floor of the door opening
(point
Ⅰ ), 5 m away on the other side of
the door opening (point Ⅱ ) and on the
upper edge of the door opening
(point
Ⅲ ).

– Set up the measuring tool on the other
side of the door opening, directly behind
point
Ⅱ . Allow the measuring tool to level
in and align the vertical laser line in such
a way that its centre passes through
points
Ⅰ and Ⅱ exactly.
– Mark the centre of the laser line on the upper edge of the door opening as point Ⅳ .
– The discrepancy d between the two marked points
Ⅲ
and
Ⅳ
reveals the actual ver-
tical deviation of the measuring tool.
