4. Datalogging
Datalogging is a feature that allows the meter to store measured parameters based on time or on occurrence of a
certain event. The user can retrieve the data later for further application.
This meter offers three types of datalogging
1) Event based 2) Time based 3) Load profile

This type of datalogging stores data when certain event is observed. This data is time stamped and last five
occurrences of each type of event are stored based on first in first out queue. This meter offers event based logging
