Digital Panel Meters FAQ
Q. Is it difficult to implement the linearization function in the UDM40?
No, it is quite easy. First, the output characteristic of the transducer must be divided into a number of segments paying attention to the maximum deviation from the curve. For example, in figure 1, we can divide the curve into 9 segments (9+1=10 linearization points) in relation to the vertical grid. The Lin menu must be activated (YES) and the number of linearization points set (10 in this example). Then the input/output coordinates of each point must be edited. For example in.01=4, ou.01=1.0, in.02=4.5, ou.02=0.9, ..., in.09=12, ou.09=0.2, in.10=20, ou.10=0.1. Note that the first and the last linearization points must correspond to the ones defined in the SCAL menu (in.01=Lo.E, ou.01=Lo.d, in.10=Hi.E, ou.10=Hi.d).
