Data Logger - GE C70 Instruction Manual

5 SETTINGS
The source harmonic indices appear as oscillography analog channels numbered from 0 to 23. These correspond
directly to the to the 2nd to 25th harmonics in the relay as follows:
NOTE
Analog channel 0 2nd harmonic
Analog channel 1  3rd harmonic
...
Analog channel 23  25th harmonic

The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data may
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, meaning that 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. Exam-
ple storage capacities for a system frequency of 60 Hz are shown in the following table.
