8. Checking the accuracy
Check the accuracy of the SOLA HORIZON GREEN before each measurement.
Before starting the check, let the device acclimatise to the environmental conditions.
8.1 Checking the accuracy of the vertical line
Attach a plumb line as close as possible possible to a (at least)
3 m high wall.
Mount the HORIZON GREEN onto a tripod at a height of approx.
1.2 m.
Position the device approx. 3 m in front of the plumb line.
Switch on the HORIZON GREEN and project the vertical laser line
onto the plumb line.
If the deviation is greater than 4 mm, the device must be readjusted.
In this case, consult your dealer.
8.2 Checking the leveling accuracy of the horizontal line
1. Select two horizontal, flat walls (A & B), which are approx. 10
meters apart.
Mount the HORIZON GREEN onto a tripod and position it at a
distance of approx. 20 cm from wall A.
Mark the intersecting point of the vertical and horizontal lines
on wall A.
2. Rotate the HORIZON GREEN by 180° and mark point on wall B.
Position the laser at the same height approx. 20 cm away from
wall B and mark point on wall B.
3. Rotate the HORIZON GREEN by 180° and mark point on wall A.
Measure the vertical distance
of the marked points -
and the vertical spacing
of the points - .
Mark the center point of
and
.
If the reference points and are on different sides of the
center point,
must be subtracted from
.
If the reference points and are on the same side of the
center point,
must be added to
.
