Drawing required
A true to scale drawing is required to set the channel parameters.

Procedure:
1. Draw a vertical auxiliary line onto the drawing from the lowest point of the
channel to the top.
2. Starting at this line, draw horizontal auxiliary lines from the distinct points of pro-
file changes to the left and to the right.
3. Measure the distances of each of these auxiliary lines starting at the centre
auxiliary line to the right and to the left.
4. Convert the results true to scale and enter the breakpoints into the 3 value col-
umns as follows:
height / width to the left / width to the right
Necessarily observe here the relevant note above on the viewing direction
with free profiles on page 73.
5. Start at level “0” to define the starting point of the channel.
6. Enter all other breakpoints “freely”. A maximum of 32 breakpoints can be en-
tered.
The distance between individual height breakpoints may vary. Not all of the 32
breakpoints need to be necessarily entered in order to define the profile since
the transmitter linearises between individual breakpoints.
In case of large irregular changes of the channel dimensions select a lower dis-
tance between breakpoints in this section.
A proportional graph of the values is indicated here too after the channel pa-
rameters have been set.
7. Use the 3D view to verify whether the dimensions are specified correctly.
Thanks to this visual aid, bad programming issues can be visualised and cor-
rected directly if required.
