Hello, my name is Daniel and i just bought a 20€ ebay DIY oscilloscope kit (DSO138)
I got it working and performs just fine, the issue is that the multiplier options are x5 x2 and x1, the volts per division options are 1V 0.1V and 10mV and the display has about 10 divisions.
I can't figure out how to make a 25V sine wave fit in the super small display this has, I have most of the sine wave going over the upper and lower display limits.
Is there any way I can modify either the oscilloscope or the signal to make 230V fit?
