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
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.

Changing any setting affecting data logger operation clears data in the log.
— This setting configures the mode in which the data logger operates. When set to "Continuous," the
DATA LOGGER MODE
data logger actively records any configured channels at the rate as defined by the
idle in this mode when no channels are configured. When set to "Trigger," the data logger records any configured channels
