Explanation
Unit of Sum Computation
In sum computation, data is summed over the scan interval. However, for flow values that
have units /s, /min, /h, or /day a simple summation results in the actual value not matching
the computed result, because the scan interval and the unit of the input values are different.
In such cases, set the sum scale to match the unit of the input value. In effect, the sum value
with the same unit as that of the input value is computed.
For example, if the scan interval is 2 s, and the input value is 100 m
3
/min, a simple
summation would add 100 every 2 s resulting in 3000 after one minute. However, if the sum
scale is set to /min, then 2 s/60 s is multiplied every scan interval before the value is added
giving a result that has an m
3
/min unit.
The following converting equations are used to compute the sum. The scan interval unit is
seconds.
Off:Σ(measured data every scan interval)
/s: Σ(measured data every scan interval) × scan interval
/min: Σ(measured data every scan interval) × scan interval/60
/h: Σ(measured data every scan interval) × scan interval/3600
/day: Σ(measured data every scan interval) × scan interval/86400
ReportProcessingwhentheMeasurementModeIsSettoDualInterval
Report computation is performed at the scan interval of each measurement group. For
example, if a channel of measurement group 1 is assigned to a report channel, computation
on that report channel is performed at the scan interval of measurement group 1. A single
report file will be created.
Report Processing When the Measurement Mode Is Set to High Speed
Report computation is performed at the scan interval.
Maximum Number of Report Channels
The following table shows the maximum number of report channels depending on the
measurement mode.
