Example 1
: standard
configuration for trans-
mitter with probe of
length PL inches or cm.
[setup by factory as
part of final assembly
procedure]
Example 2
: end user desires 0 to
100% output for a subset of the
measureable region [probe]
[e.g., for a chamber application]
Example 3
: same configuration as
previous except Direct [no] scaling
setup in AI block
Output to FF segment is in cm
