Zero point "Z" in linear
conversion formula
Slope "A" in the linear
conversion formula
The linear conversion formula is Y = A × (X-Z), where Y is the target collection quantity,
X is the input analog, Z is the zero point, and A is the slope.

A 4– 20mA PT100 thermometer is connected, where 4mA corresponds to 0℃ and
20mA corresponds to 120℃.
The target collection quantity Y is temperature, and the input analog amount X is 4-
20mA sampling current.
It is obtained by calculation that Z=4 and A=7.5.
Thus, enter 4 and 7.5 in fields zero point and slope respectively.
