The setting determines the sampling rate at which AC input signals (that is, current and voltage) are
AC INPUT WAVEFORMS
stored. Reducing the sampling rate allows longer records to be stored. This setting has no effect on the internal sampling
rate of the relay which is always 64 samples per cycle; that is, it has no effect on the fundamental calculations of the device.
When changes are made to the oscillography settings, all existing oscillography records will be CLEARED.

A setting selects the FlexLogic operand state recorded in an oscillography trace. The length of each
DIGITAL 1(63) CHANNEL
oscillography trace depends in part on the number of parameters selected here. Parameters set to "Off" are ignored. Upon
startup, the relay will automatically prepare the parameter list.
