– Align the height of the measuring tool (using a tripod or by 

underlaying, if required) in such a manner that the cross 
point of the laser lines is projected against the previously 
marked point

II on the wall B.

– Without changing the height, turn around the measuring 

tool by 180°. Direct it against the wall A in such a manner 
that the vertical laser line runs through the already marked 
point

I. Allow the measuring tool to level in and mark the 

cross point of the laser lines on the wall A (point

III).

– The difference d of both marked points 

I and III on wall A 

results in the actual height deviation of the measuring tool 
alongside the lateral axis.

On the measuring distance of 2 x 5 m = 10 m, the maximum 
allowable deviation is: 
10 m x ±0.2 mm/m = ±2 mm. 
Thus, the difference d between points 

I and III must not ex-

ceed 2 mm (max.).

Checking the Levelling Accuracy of the Vertical Line
For this check, a door opening is required with at least 2.5 m 
of space (on a firm surface) to each side of the door.

– Position the measuring tool on a firm, level surface (not on 

a tripod) 2.5 m away from the door opening. Allow the 
measuring tool to level in while in vertical operation with 
automatic levelling, and direct the laser beam at the door 
opening.

– Mark the centre of the vertical laser line at the floor of the 

door opening (point

I), at a distance of 5 m beyond the 

other side of the door opening (point

II) and at the upper 

edge of the door opening (point

III).

– Rotate the measuring tool by 180° and position it on the 

other side of the door opening directly behind point 

II. Al-

low the measuring tool to level in and align the vertical laser 
line in such a manner that its centre runs exactly through 
points 

I and II.

– Mark the centre of the laser line at the upper edge of the 

door opening as point 

IV.

– The difference d of both marked points 

III and IV results 

in the actual deviation of the measuring tool to the plumb 
line.

– Measure the height of the door opening.

The maximum admissible deviation is calculated as follows:
Doubled height of the door opening x 0.2 mm/m
Example: For a door-opening height of 2 m, the maximum de-
viation may be
2 x 2 m x ±0.2 mm/m = ±0.8 mm. Consequently, points 

III 

and 

IV may be no more than 0.8 mm (max.) apart from each 

other.
