Parameter values 9, 10, and 14...17 use the formula in the following table.
Value
AI reference is calculated as following:
Setting
C + B
C value + (B value - 50% of reference value)
C * B
C value * (B value / 50% of reference value)
C - B
(C value + 50% of reference value) - B value
C / B
(C value * 50% of reference value) / B value
Where:
• C = Main Reference value
( =

COMM
=
1 for values 14...17).
AI
• B = Correcting reference
( =
1 for values 9, 10 and
