Aggregation
Accura 2300S/2350 sense and process voltage/current signals every 0.5 seconds and provide the data
measured at 0.5-second intervals every 0.5 seconds. Using the data, aggregation for the interval longer
than 0.5 seconds is performed as shown in the figure below. This figure shows the aggregation process
for 1-second and 5-second intervals.
Aggregated data include the average value, the maximum/minimum values, and timestamp data for the
maximum/minimum values. The average, the maximum/minimum values and the timestamp data are
generated for each aggregation interval. The average value is the average of the data obtained during
the aggregation interval of 0.5 seconds. The maximum/minimum values are the maximum/minimum
values among the data obtained during the aggregation interval.
The timestamp data for the maximum/minimum values indicate the time difference between the start
time of the aggregation interval and the occurrence time of maximum/minimum values. Therefore, the
actual time data for the maximum/minimum values can be obtained by adding the start time of the
aggregation interval and the timestamp data.

Fixed Aggregation
Accura 2300S provides six aggregation intervals from Aggregation 1 through 6(1 second, 5 seconds, 1
minute, 5 minutes, 1 hour, and 6 hours). In fixed aggregation interval, the offset time for the start of the
aggregation interval is fixed to zero. That is, the start time of the aggregation interval is set to 0 hours
0 minutes 0 seconds. To set the offset time to a non-zero value, you should use the custom
aggregation function.
The values displayed on the LCD screen of Accura 2300S are the values measured at 2-second
aggregation intervals and updated every 0.5 seconds, and the data are provided via communication
through Aggregation 201 setup.
In addition, the Max/Min values displayed on the LCD screen after resetting the values are the Max/Min
values among the data obtained during the aggregation interval of 0.5 seconds, and the data are
provided via communication through Aggregation 202 setup.
