Press this key, the oscilloscope will automatically adjust the vertical scale, scan time base
and trigger mode according to the input signal to realize optimum waveform display.
Note: Waveform auto setting function requires that the frequency of sine is no lower than
20 Hz; the amplitude must be at least 20 mVpp~120 Vpp. Otherwise, the waveform auto
setting function may be invalid.
Press this key set the operating state to "RUN" or "STOP".
In the "RUN" state, the key is illuminated in green.
In the "STOP "state, the key is illuminated in red.
