The "LowScale" and "HighScale" parameters
allow a concentration value to be set to corre-
spond to the lower (0 or 4 mA) or upper signal
value (20 mA). The limis for these parameters
are given by the "MinRange" and "MaxRange"
parameters, specifying the physical measu-
ring ranges of each instrument (
page 5-27).
Concentrations outside the range defined by
"LowScale" and "HighScale" are not suppor-
ted by an analog output.
Note!
Scaling may affect the analog outputs
accuracy!
Carefully read the information, given in (
5.7.4.1, page 5-27 before scaling analog
outputs!
The last line on this menu allows the zoom
function of the analog output to be set when
that output has been assigned the Zoom
signal.
This function allows a part of the signal range,
specified by "LowScale" and "HighScale", to
be "magnified" on the analog output. Unlike
the scaling function, here the output is swit-
ched automatically, the moment the switching
point concentration is reached.
