Checking the Height Accuracy of the Horizontal Line

For this check, a free measuring distance of 5 m on a firm surface between

two walls A and B is required.

– Mount the measuring tool onto a tripod or place it on a firm and level

surface close to wall A. Switch on the measuring tool. Select cross-line

operation with automatic levelling.

– Direct the laser against the close wall A and allow the measuring tool to

level in. Mark the centre of the point where the laser lines cross each

other on the wall (point I).

– Turn the measuring tool by 180°, allow it to level in and mark the cross

point of the laser lines on the opposite wall B (point II).
