Using the Oscilloscope
40
To clear the waveform display
Press the [Clear Display] key.
The oscilloscope clears the waveform display. If the oscilloscope is in Run
mode and is receiving triggers, it will update the display as it collects new
waveform data. Clearing the waveform display also resets averaging, infinite
persistence, color grade persistence, histogram, mask testing, and
measurement statistics.
