Press enter to confirm.
Entered value applies to
selected process variable/range.
If the adjusted range is

Bilinear curve:
Vertex X/Y
Enter value using
keys.
Press enter to confirm.
Entered value applies to
selected vertex of bilinear curve
"Corner X“ (process variable)
and "Corner Y" (output current)
– see figure below.
Vertex of bilinear curve
Output current
Process variable
Example:
Current range 4 ... 20 mA
Current start: 0 µS/cm
Current end: 200 µS/cm
Vertex:
“CORNER X“: 10 µS/cm (process variable)
“CORNER Y“: 12 mA (output current)
Result: The output current change in the range 0 ... 10 µS/cm
is much greater than in the range 10 ... 200 µS/cm.
