Call up the program
"Stakeout".

The program "Stakeout" assumes
that the instrument is set and
oriented to a known point.
If "Point Id" has not been entered, the
function is not available.

Exit the program.

• Lateral point 3 coordinates (E, N)

Given
• Baseline Start Point 1 (E, N),
• Baseline End Point 2 (E, N),
• Difference in length/abscissa

(Horiz. Dist.)

• Lateral deviation/ordinate (Offset)

Station coordinates and
orientation need to have

been set correctly before the
coordinates of point 1 resp. point 2
can be determined by measurement.

Explanation of the polarity
rule of Horiz. Dist. and Offset

During entering, the polarity is based
on the straight line 1 -> 2.
