5.4 Transient Mode
Press the transient display mode button -
Transients are displayed in the form of waveforms. All channels (up to 6, based
upon configuration) are stored in memory for each transient. Up to 50 transients
can be captured, which include the pre-tripped waveform, the tripped waveform
and two post trip waveforms for each active input.
The function buttons have the following functions in this mode:
- Starts capture search programming for
a new transient
- Stops capture search
- Displays a captured transient
- Deletes a captured transient
