Hello All :o The example of scaling input data for the F0-2AD2DA-2 (on page 12-12) is confusing to me because the numerator is 100 and does not seem to change the denominator what if the numerator was 135. Or in other words the units were 2024 the high is 135 degrees the low 0 degrees and the denominator is 4095 what would the temperature be? Brine

(Raw Value / Total Units) * Max Engineering Units = X
(2024 / 4095) * 135 = 66.73 degrees
AX + BY
A
- * Y
B
2024 66.73
----- : ------
4095 135

Also don't forget that the target EU range doesn't always have one end at zero, particularly for temperature transmitters. The range is often something like 30-300F. In that case you need to multiply the analog input percentage by the EU range (270 in my example), then add the minimum EU value, 30.
