This feature compares two of the analog inputs and activate alarms or trips based on the difference between
them. The difference can be of an absolute difference in units or a percentage difference. The second analog
input (4 for 3-4) is used as the reference value for percentage calculations. The comparison logic can also be
selected as one input greater than the other ("3>4") or vice versa ("4>3") or as absolute difference ("3<>4").
Note that the compared analog inputs must be programmed with the same unit type prior to using this feature.
