Additional calculations (used conversion characteristic)
The manner of the additional computation of the displayed result depends on selected
conversion characteristic. All presented charts are connected with the input range
4
– 20 mA.
10.1.1. Linear characteristic
The normalized result is converted by fixed coefficients determined by
“Lo C”
and
“Hi
C”
parameters (when the normalized results is equal 0, then value
“Lo C”
is displayed,
and when the normalized results is equal 1, then value
“Hi C”
is displayed). Expression
presented below shows the manner of result calculation:
where W means the displayed value.
The value of the
“Lo C”
parameter can be higher than the value of
“Hi C”
parameter. In such a case, for an increasing value of input current the
displayed value decreases.
