Scaling
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 according to each segment.
The pictogram
is displayed on the screen in the active window when the scaling function is enabled.
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.
In emission mode: X = Value displayed and 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
To select a line in a list, use the Up and Down navigation keys.
To delete a selected line, use the
To move from one field to the next, use the
The Define/parameters menu makes it possible to define the format (Number of digits displayed) and unit.
Once the parameters have been set, the scaling is automatically enabled. To disable it, enter the Configuration/Scaling menu, select OFF and confirm by
pressing the VAL key.

Remarks:
The parameters and scaling points are saved when turning the unit off.
Beware, when changing functions (thermocouple or resistive sensor) or units, scaling goes OFF. The data defined in the point lists are then erroneous.
