Turn the measuring tool 180° without adjusting the height. Aim it at wallA
such that the vertical laser line runs through the already marked point.
Allow the measuring tool to level in and mark the point where the laser
lines cross on wallA (point).
The discrepancy d between the two marked points and on wallA re-
veals the actual height deviation of the measuring tool.
The maximum permitted deviation on the measuring distance of
2×5m=10m is as follows:
10m×±0.5mm/m=±5mm. The discrepancy d between points and
must therefore amount to no more than 5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 a tri-
pod, or place it on a firm, level surface. Select horizontal mode with auto-
matic levelling and allow the measuring tool to level in.
