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,
specied by “LowScale” and “HighScale”, to
be “magnied” on the analog output. Unlike
the scaling function, here the output is swit-
ched automatically, the moment the switching
point concentration is reached.
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 ( 5.7.4.1,
page 5-27).
Concentrations outside the range dened 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!
