Reading: 372,080 gon                          

Telescope camera coverage from "DAHLTA 010 B"

Reading:

s = 0,292 m * 100 = 29,2 m

/\  h = 0,217 m (+20) = - 4,34 m
Application:
-the vertical line of the line plate must be in the centreof the levelling rod.
-the basic curve goes through the whingmark of the leveling rod.
-the levelling rod reading for the distance is the pitch of the basic curve to the distance curve.
-the height reading is from the basic curve to the distance curve.
-before reading of the height difference must be horizontal in the height index level
