Extending straight lines
Procedure:
Carry out steps 1 to 3 (see SIMPLE method).
4. Turn instrument around the standing axis and aim on
point B again.
5. Turn telescope around the tilt axis and stake-out an
auxiliary point C2 in the same distance as C1.
Wanted: The straight line from A to B should be extended. A new point C is created.
SIMPLE method ACCURATE method
Result:
Point C is in the middle of line C1 to C2.
Procedure:
1. Set up instrument above point A and level up.
2. Aim on point B in face one.
3. Turn telescope around the tilt axis and stake-out point
C1 in the desired distance.
To ensure accuracy:
