Selects which waveform to zoom (only in U,I or U/I ).
Returns to the “TRANSIENT RECORDER” screen.
3.16.4 Captured transients
Captured transient records can be viewed from the Memory list where captured waveforms can be
analysed. Trigger occurrence is marked with the blue line, while cursor position line is marked in black.
