The vertex values of the function transmitters are given in % and not physically here
because of their free utilization.
Setting takes place in the structure mode oFPA in the range from --199.9 to +199.9 %.
The vertex values 0 and 100 are set with 0 % or 100 % so that x
1
(l) is available again as a
standard variable and the reference junction terminals for determining the display range of
the digital display are correct. The display range is set with the parameters dA*, dE* and dP*
according to the physical measuring range.
To determine the vertex values, apply the sensor function as shown in fig. 1-21 and divide
the range into 10% steps (x
phys
in %). Then read off the % values in the vertex positions
--10 to 110 on the x
phys
-axis and enter one after the other in the structuring mode oFPA.
