Parameters for generation of a linearisation curve
Parameters described under this section will not appear in the menu when the linearisation has
been switched off by setting „Linearisation Mode“ to „no“.
„Linearisation Mode“ has to be set to either „1-quA“ or „4-quA“ to enable the linearisation
function. This will change the linear measuring results into a non-linear display and a
corresponding analogue output.
There are 16 interpolation points available, which can be freely arranged over the whole
measuring range in any distance. Between two points the unit automatically will interpolate
straight lines. For this reason it is advisable to set many points into areas with strong bending,
and to use only a few points in areas with little bending.
Parameters P01_x to P16_x select 16 x- coordinates, representing the display values which the
unit would normally show in the display.
With parameters P01_y to P16_y you can specify now, which values you would like to display
instead of the corresponding _x values.
This means e.g. that the unit will replace the previous P02_x value by the new P02_y value.
x- registers have to use continuously increasing values, e.g. the lowest display value
must be set to register P01_x, and the highest display value must be set to P16_x
Independent of the selected linearisation mode, the possible setting range of all
registers P01_x, P01_y,…, P16_x, P16_y is always -99999 … 99999.
1.
Linearisation-Mode = no
All linearisation is switched off and the linearisation parameters do not appear in the menu
2.
Linearisation-Mode = 1_quA
Linearisation is defined for positive values only, e.g. for display values 0, …, 99999.
Negative display values will appear as a mirror of the positive settings.
To avoid discontinuity it is advisable to set the (P01_x, P01_y) coordinates to the zero point of the
measuring range. Negative settings are allowed for y-coordinates only, but not for x-coordinates.
3.
Linearisation-Mode = 4_quA
Linearisation is defined over the full numeric range (i.e. -99999, …, 99999)
4.
For measuring values outside of the defined linearisation range, please note:
If the measuring value is lower than P01_x, the linearisation result will always be P01_y.
If the measuring value is higher than P16_x, the linearisation result will always be P16_y.
