8. Measure the distance between mark and mark
on target
and mark and mark on target .
If the distances are the same, the laser is level.
9. If the distances are not the same, subtract the lesser
m
easurement from the greater measurement and divide
by two to calculate the difference of error.
If the distance is ≤6 mm @ 30 m, the laser is within
c
alibration accuracy.
