8. Checking the leveling accuracy
Check accuracy of the SOLA PROTON before each measurement.
Before starting the check let the device acclimate to the environ-
mental conditions.
1. Position the laser 30m away from a wall and allow it to level itself
horizontally.
2. Move the receiver up and down until the +y-axis is positioned
on the height of the laser beam. Use the marking notch as a
reference and mark the height on the wall.
Note:
For increased precision, use the fine adjustment (1 mm) on
the receiver REC RRD0 (PROTON S).
3. Rotate the laser by 180° (the -y-axis must be facing the wall) and
allow it to re-level itself.
4. Move the receiver up and down until the y-axis is positioned
„on the height“ of the laser beam. Use the marking notch as a
reference and mark the height on the wall.
5. Measure the difference between the two marks. The laser must
be calibrated if the difference is greater than 6mm at a distance
of 30mm.
6. After adjusting the Y-axis, rotate the laser by 90°. Repeat the
steps 2-5, and start with the + x-axis pointing towards the wall.
