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. Note: auto setting requires that the
frequency of the signal under test should be no lower
than 25 Hz. If the parameter exceed the limit, “Can’t
detect any signal!” would be displayed after pressing this
key and the quick parameter measurement menu might
not be displayed.
