Strange problem with DSO 138 - trace rises to infinity
Posted: Sun Nov 12, 2017 6:46 pm
Hello,
I have quite a strange problem with my DSO 138 oscilloscope - a few seconds after turning on my oscilloscope (even without probes) the traces immediately rises over the visible screen, no matter what settings I'm using. Measurements of voltage seem to continuously increase up to over 1000V which is of course not happening in reality! What is also interesting, is that it worked before and suddenly broke down. In attachment I add a picture. Can you please help me?
