i just received my first o-scope from the ups guy today, and fooling around with it, i noticed (instantly) that the trace will display fine one second, then jump down to where it is only half visible and somewhat blurry. it jumps back and forth from these states randomly. seeing as how this is my first scope i dont have any idea what would cause this, let alone how to fix it. all of the controls work fine, and seemingly independent o the problem with the trace.
it is a protek p-3502. any suggestions or guidance on what to do would be greatly appreciated!
