Chapter 4 Measurements
General Measurement Parameters
General measurement parameters are shown in the table below. All parameters are supported by
communication and some parameters are also displayed on the front LCD screen of Accura
3300E.
Measurement values displayed on the front LCD screen of Accura 3300E are aggregated values
for the 1-second interval based on the basic measurement data collected for the 0.2-second
interval.
Measurement values supported by communication are aggregated values for one aggregation
interval selected among 1 second, 5 seconds, and 1 minute. The aggregation interval is 1 second
by default.
The maximum and minimum values provided on the Accura 3300E screen after resetting the
max/min values are stored in non-volatile memory. Thus, the data are maintained even when
Accura 3300E is turned off and then on.
Peak demand is reset to 0 not by demand reset but by resetting the maximum/minimum values.
