This parameter will be available only when the split range is
enabled ("SPLt." [C.F01] = "Enb").
Range: from -100.0 to 100.0 % of the output span.

This parameter will be available only when main control output is
configured.
Range: norñ = The control output is calculated by the PID
CñPL = The control output is complemented (100-PID
calculated value)
Ouic = The control output is conditioned to match a
“QUICK OPENING” flow characteristic
Eou = The control output is conditioned to match an
“EQUAL PERCENTAGE” flow characteristic

Sometimes non linear valves are used where a linear valve is
suitable.
In these cases, it is advisable to linearize the ratio between flow
rate and valve travel in order to obtain a better control of the
process.
This instrument allows you to select an output linearization in
accordance with the two most common valve flow characteris-
tics:
- Quick opening
- Equal percentage.
