19. Arc Staking Out Measurement

Stake out a designed arc by arc staking out measurement, see below figure, after define

the arc by 2points-arc or 3points, the instrument will help you move the rod to the arc.

Here:

S.P– Start point of arc

E.P– End point of arc

C.P– Circle center point of arc

Station(from S.P to A) - the station on the arc computed radially from the current

position of the prism.

Offset(from rod to B) – offset distance from the current position to the arc.

S-O dHA – If your line of sight does not intersect the arc, it will display to ask you rotate

you telescope until sight line intersect the arc, and then In/Out will display. Offset angle

is from the current position to the arc

Fill/Cut – Cut value indicate that the rod is higher than the arc, fill indicates the it is

lower

In/Out(from Rod to A)– This is the distance you need to move in out to get to the arc.
