I think you should find a way to return it and purchase the latest 12bit oscilloscope from Puyuan. Why do I say that? Because I also bought a 1112, but I am very disappointed. It is a repaired product and the waveform noise is very loud. The staff has always emphasized that there is no problem. I have OCD and I would not want this kind of defective product.
