Soil Cal
– allows you to use hyperbola-fitting to determine a more accurate Soil Cal.
The options are slightly different, depending whether or not you are in backup mode.
If the backup indicator is on the screen when you press Soil Cal, then moving the
RD1100 back and forth will adjust the vertical position indicator. The operator will
typically move the system until it is over the hyperbola in question. You can then adjust
the vertical position of the horizontal scroll bar by touching the screen and dragging it, or
using the up & down keypad arrows. Move the scroll bar such that it lines up with the
top of the hyperbola in question (Figure 8-11).

Alternatively, if you press Soil Cal while you are collecting data or have pressed Pause , you will
see a red hyperbola in the middle of the screen. Drag the hyperbola such that it lies over a real
hyperbola from the ground (Figure 8-12). You can use the 4-way keypad arrows to fine tune the
movements.

it lies over a hyperbola from the ground and adjust the shape (Right)
