TRIGGER POSITION
position of 25% consists of 25% pre- and 75% post-trigger data.
— Always captured in oscillography and can be any FlexLogic parameter (element state, contact input,

virtual output, and so on). The relay sampling rate is 64 samples per cycle.
AC INPUT WAVEFORMS
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 are cleared.
