CLEAR
Press this key to clear all the waveforms on the screen. If the
oscilloscope is in “RUN” state, new waveforms will be
displayed.
AUTO
Press this key to enable the waveform auto setting function.
The oscilloscope will automatically adjust the vertical scale,
horizontal time base, trigger mode and so on 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: The waveform auto setting function requires that the
frequency of sine should be no lower than 20 Hz, the duty
cycle is greater than 1% and the amplitude is 20 mVpp at
least. If the parameter exceeds this limit, the waveform auto
setting function might be invalid.
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. When the
oscilloscope is in wait-for-trigger state (the key is illuminated
in orange), pressing FORCE will generate a trigger signal
immediately.
