After loading, the Ref waveform status will be displayed in the lower left corner, including time base scale and amplitude
scale. At this point you can use the vertical and horizontal control knob to adjust the Ref wavform’s position on the screen,
the time base scale and the amplitude scale.
Remark:
Only when the oscilloscope is connected to an external USB storage device such as a USB flash drive can you select
the disk as USB, and then save the settings to the USB storage device. When the USB storage device is not connected,
it will prompt “USB device is not inserted”.
When loading, the disk and file name must be set to match the one previously saved, if the settings have not been saved
to the selected location before, it will prompt ”Load Failed”.
