INP-
n
This parameter is available for viewing and editing only when the
correction type is set to Non-linear.
Enter the normalised input value for the correction point.
The instrument uses linear interpolation between the correction points.
An input and an output value are entered for each correction point. The
values are normalised between the minimum point (0.0) and the
maximum point (1.0). Only the points between 0 and 1 are required to be
entered and should be entered in ascending order.
The following diagram shows a 5 point linearised representation of the
input for a hypothetical flowmeter. The heavy black line represents the
actual input from the flowmeter. The light black line is the approximation
that the instrument uses.
You can press the key to skip the non-linear points and go to the
next item.
OUT-01 AINP3
to
AINP4
OUT-
n
This parameter is available for viewing and editing only when the
correction type is set to Non-linear.
Enter the normalised output value for the correction point.
STACK AINP3
Select YES to stack AINP3 as the low range input with AINP4 as the high
range input.
Select NO to use AINP3 as the only flow input.
