Relation between input current and calculated concentration
Figure 52 shows the output value depending on the input current, the set low value and
the set high value with an input range of 0
–20 mA.
The output value (OV) is a function of the input current (IC).
The output value is determined according to formula (3):
(3)
where:
OV=Output value
IC=Input current
LV=Low value
HV=High value
