DISPLAYING DATA 2-13
Historic Data Logging Framework

This portion of the meter’s configuration records ‘standard’ power system

parameters such as voltage, current, power, frequency and power factor.

Low, mean and high values are recorded for all parameters. N ote that

‘low’ and ‘high’ are different from ‘min’ and ‘max’: low and high are reset

every 15 minutes, whereas min and max are typically long-te rm

measurements that are only reset by the operator. Similarly, ‘mean’ is

reset every 15 minutes, unlike ‘average’ which is typically an instantaneous

averaging of multiple real-time measurements.
