Operation without the automatic compensation (see fig. D)
The On/Off (D) must be in the middle position to work without the automatic
compensation.
This mode allows constructing inclined planes.
At the switched off automatic compensation you can freely hold the
instrument in your hand or place it on a suitable surface. Two laser lines are
not always constructed as orthogonal in the mode of crossing lines.
Accuracy Check
Influence on accuracy
The ambient temperature has the greatest influence. Especially temperature
differences occurring from the ground upward can divert the laser beam.
As thermal fluctuation is largest close to the ground, the instrument,
if possible, should be mounted on a commercially available tripod and
placed in the centre of the working area. Apart from exterior influences,
instrument-specific influences (such as heavy impact or falling down) can
lead to deviations. Therefore, check the accuracy of the instrument each
time before starting your work.
Checking of the horizontal line
For this check, a free measuring distance of 5 meters on a firm surface
between two walls A and B is required.
Mount the instrument onto a tripod or place it on a firm and level surface
close to wall A. Switch on the instrument. Select cross-line operation with
automatic leveling
Direct the laser against the close wall A and allow the instrument to level
in. Mark the centre of the point where the laser lines cross each other on
the wall (point I).
