Performing a self-alignment
The self-alignment aligns the data from several input channels vertically and horizon-
tally to synchronize the timebases, amplitudes and positions.
Recommendation on performing the self-alignment:
●
When putting the instrument into operation for the first time
●
After a firmware update
●
Once a week
●
When major temperature changes occur (> 5°)
