AUTO
Press this key to enable the waveform auto setting
function. The oscilloscope will automatically adjust the
vertical scale, horizontal time base and trigger mode
according to the input signal to realize optimum waveform
display. Besides, the quick parameter measurement
function is also provided (for more details, refer to “
Quick
Measurement after AUTO”).
Note: Auto setting requires that the frequency of the
signal under test should be no lower than 50 Hz, the duty
cycle be greater than 1% and the amplitude be at least 20
mVpp. If the parameters exceed these limits, “Can’t
detect any signal” would be displayed after pressing this
key and the quick parameter measurement menu might
not be displayed.
RUN/STOP
Press this key to set the state of the oscilloscope to
“RUN” or “STOP”. In “RUN” state, the key is illuminated in
yellow and red in “STOP” state.
SINGLE
Press this key to set the trigger mode to “Single”. In
single trigger mode, the oscilloscope generates a trigger
when the trigger conditions are met and then stops.
