So I have just received my scope minus manual. It is the e-design minidso DS0201. I see Seed’s manual on line for the nano but still is not answering my question. So my first is how do you switch from 1x to 10x. There is a switch on the probe but it doesn’t change the 1x/10x on the screen when i switch it. It always says 1x probe. And my last question is what are those colored rings that go on the probe for. I have never seen that on any benchtop oscope. Thanks .
