This parameter is available for viewing and editing only when the
correction type is set to Linear.
The K-factor of the flowmeter is the number of pulses from the flowmeter
per unit of volume. The K-factor cannot be 0 (zero).
NO-PTS FINP1
FINP2
This parameter is available for viewing and editing only when the
correction type is set to Non-linear.
Enter the number of non-linearity correction points.
Press or to select a number between 1 and 10 for the number
of correction points.

This parameter is available for viewing and editing only when the
correction type is set to Non-linear.
Enter the frequency for this correction point.
The instrument uses linear interpolation between the correction points
except that the correction factor for FREQ01 is used from 0 Hz up to
FREQ01. Similarly, the instrument maintains the correction factor for the
highest frequency setting up to the maximum input frequency.
The following diagram shows the scaling factors at different frequencies
for a hypothetical flowmeter. The heavy black line represents the actual
scaling factor of the flowmeter. The light black line is the approximation
that the instrument uses.
Enter the lowest correction factor frequency as FREQ01 and proceed up
to the highest frequency. You can hold the
key to skip the
non-linear points and go to the next item.
