ihTotal Mode

The ihTotal mode retrieves the time weighted rate total for each calculation interval.

A rate total is considered for totalizing a continuous measurement. A factor is applied to the totalized value to convert into the appropriate engineering units. Since this is a rate total, a base rate of Units/Day is assumed. If the actual units of the continuous measurement is Units/Minute, multiply the results by 1440 Minutes / Day to convert the totalized number into the appropriate engineering units.

The formula for total is total = average & (interval in milliseconds / 1000) / 86400. The 86400 is number of seconds in a day. This formula takes the average, which is assumed to be already in units per day, and divides it into "units per interval".
