Scaling

The scale correction function performs conversion operations between the electrical values measured and the
physical values converted.
This linearization operation makes it possible to partially correct the errors induced by non-linear
sensor/converter systems.
The Scaling function allows definition of up to 11 correction values, i.e. 10 segments, in order to approach as
much as possible the non-linear response curve, and to make the scale corrections according to each defined
segment.
The pictogram
The 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 and Y = Value Displayed.
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:
