Have you ever wondered why your calculated 1-hour average isn’t the same value as shown on the controller? The reason might be the type of math channel that is used. The 1-hour average from an M-type math channel will differ from the 1-hour average calculated using a P-type math channel.
M-type math channels take the instantaneous values of the constituents of an equation and evaluates them, then averages the values together to get the desired interval value. In a P-type math channel, the interval values of the constituents are used to produce the channel value for that interval.
