Scaling
It is only necessary to scale the meter when it has been configured for a process or a load cell
input signal. When configured for temperature sensor input the meter is automatically scaled
to a fixed range based on the temperature sensor. Scaling consists of assigning a display value to
each input signal value.
In linear processes
it is achieved by programming two coordinates (InP1, DSP1) and (InP2,
dSP2), between which is established a linear relation where each input signal value corresponds
to a display value. The relationship can be direct or reversed. In order to obtain more accuracy,
points 1 and 2 should be located approximately at both extremes of the process.

Reversed scale
In nonlinear processes it is possible to program up to 11 input to display points. Each two
points are connected by a straight line and the whole is a curve that represents the relationship
between the input value and the display value.
