– 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.

– 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).

– 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.
