Linearization Incorrect!
Flowrate Ax
negative slope!
With active linearization function, the number of linearization points for parameter
„linearization points“(in addition to point A0) is set fixed. Depending on the setting of
this parameter, the other input parameters are shown in the menu. Input signals above
the last point linearization are processed with the pulse rate of the last point.
Conditions for the base sequence:
The sensor curve must be monotonically increasing, since the frequency values
increase continuously with increasing flow.
Inconsistent base sequence
After entering the linearization points, a check is carried out for consistency when the
user exit the menu item "Signal Input".
Should one or more bases not comply with the Terms Security for the base sequence,
the below message box appears:
Such a case is illustrated in the graph below, in which Q2 <Q1, thus having a
negative slope between K
2
and K
1
.
To correct this error, the bases must be checked and corrected if necessary. This
must always apply:
