4.1 Scaling (linearisation)
The scale correction function performs conversion operations between the electrical values measured
and the physical values converted.
This
linearisation operation makes it possible to correct partially the errors induced by non-linear
sensor/converter systems.
The Scaling function makes it possible to define up to 10 right-segments, i.e. 11 points, in order to
approach as much as possible the non-linear response curve, and to make the scale corrections ac-
cording to each segment.
The pictogram

is displayed on the screen in the active window when the scaling function is ena-
bled.
The
Configuration/Scaling/Define/List of Points menu makes it possible to program up to
10 lines of 2 values
X and Y= f(X)
In measurement mode:
X = Value measured
Y = Value Displayed.
In emission mode:
X = Value displayed
Y = Value emitted.
The lines entered are sorted according to the X in increasing order, to scale an X-value, the device
seeks the 2 lines n and m=n+1 which frame it, and extrapolates linearly:
Y = Yn + (X-Xn) x (Ym-Yn)/(Xm-Xn)
Use the function keys to edit the points:
To add a line: enter X and Y, then enable the
function key.
To select a line in a list, use the Up and Down navigation keys.
To delete a selected line, use the
key.
To move from one field to the next, use the key.
