Comparator Data Setting
●Comparative operation type
In the AM-215A, use the comparator data to select one type of
comparative operation from the three types below:
4.1.3
Scaling Data Setting
●Displayed value setting
The concept of the scaling data and an example setting of a
full-scale value are presented below:
Displayed value = (a×X) + b
a = (Displayed full-scale value - Displayed offset value) / (Input
full-scale value - Input offset value)
b = Displayed offset value - (Input offset value×a)
where
X: Input value; a: Gain; b: Offset
●Analog output setting
The range of displayed values of the AM-215A’s analog output can
be arbitrarily set, such that it corresponds to the range of 4-20
mA or 0-10 V. Analog output scaling sets a displayed value to the
analog output HI that corresponds to 20 mA or 10 V. Likewise, it
sets a displayed value to the analog output LO that corresponds
to 4 mA or 0 V.
The scaling concept is presented below:
The operation for scaling is the same as that for the displayed
value setting.
