A new record may automatically overwrite an older record if
TRIGGER MODE
is set to “Automatic Overwrite”.
Set the
TRIGGER POSITION
to a percentage of the total buffer size (for example, 10%, 50%, 75%, etc.). A trigger position of
25% consists of 25% pre- and 75% post-trigger data. The
TRIGGER SOURCE
is always captured in oscillography and may be
any FlexLogic parameter (element state, contact input, virtual output, etc.). The relay sampling rate is 64 samples per cycle.
The
AC INPUT WAVEFORMS
setting determines the sampling rate at which AC input signals (that is, current and voltage) are
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
DIGITAL 1(63) CHANNEL
setting selects the FlexLogic operand state recorded in an oscillography trace. The length of each
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.
