Position
Available for
Stake tunnel
. To stake the point automatically.
The instrument aims toward the point at the given chainage
and offsets and measures a distance. If this distance is not
within the required tolerance an iterative process is started
until:
•
the number of iterations set as the parameter
Maximum
iterations
is reached, or
•
the difference between the measured point and the
design point is less than the value set as the parameter
Position limit
