Q. What is the relationship between the
parameters of the SCAL menu?
The parameters Lo.E and Hi.E are the ends of
the electric range inside which the input signal should normally be
during the standard working. The Lo.E-to-Hi.E range must be included
in or be equal to the selected range of the input module. The parameters
Lo.d and Hi.d are the ends of the relevant range of the measured physical
variable: the values Lo.d and Hi.d will be displayed corresponding
respectively to Lo.E and Hi.E, as explained in figure 1. It is not
necessary that Lo.d be lower than Hi.d: it means that we can realise
a reverse characteristic with the UDM display.
