Linearization
The linearization function of this unit allows converting a linear input signal into a non-linear
developing (or vice versa). There are 24 programmable x/y coordinates available for input 1 and input 2,
which can be set in any desired distance over the full conversion range. Between two coordinates, the
unit uses linear interpolation. Therefore it is advisable to use more coordinates in a range with strong
curves and only a few coordinates where the curvature is less.
To specify an individual linearization curve, the parameter LINEARISAZATION MODE must be set to
either 1 QUADRANT or 4 QUADRANT (see following diagram).
The parameters P1(X) to P24(X) are used to specify the coordinates on the x-axis. These are the
measuring values that the unit normally would generate according to the actual input signal.
Now enter the attached values to parameter P1(Y) to P24(Y). These are the values that the unit will
generate instead of the x- values, i.e. P5(Y) replaces P5(X) etc.
The X-Coordinates must use continuously increasing settings, i.e. P1(X) must have the lowest and
P24(X) must have the highest setting. If the measured value is bigger than the last defined X-value, the
corresponding Y-value is displayed.
Mode: 1 Quadrant:
Mode: 4 Quadrant:
P1(X) must be set to zero. Linearization is only
defined in the positive range and the negative
range will be mirrored symmetric to central
point.
P1(X) can also be set to a negative value. If the
measured value is smaller than P1(X), P1(Y) is
displayed.
