Data storage:
Level test measurements are stored in a special line
of the selected job. The line name is predetermined
and is called "Check & Adjust" .
Should the level test result in a line-of-sight
error >100", an error message is displayed.
With the "A x Bx" procedure make sure that for the
first station B1 is not erroneously measured. This
can lead to a wrong, large line-of-sight error (<100")
that the system does not recognize as faulty.
