SETTINGS  PRODUCT SETUP  DATA LOGGER
 DATA LOGGER

The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data can
5
be downloaded to EnerVista UR Setup and displayed with parameters on the vertical axis and time on the horizontal axis.
All data is stored in non-volatile memory, so the information is retained when power to the relay is lost.
For a fixed sampling rate, the data logger can be configured with a few channels over a long period or a larger number of
channels for a shorter period. The relay automatically partitions the available memory between the channels in use. The
following table outlines examples of storage capacities for a system frequency of 60 Hz.
