Is that AC or DC coupling? You need to use DC coupling. You also need to set the 'variable' to the cal position (fully clockwise).
You also need to post the settings for the vertical amp and timebase on the scope. In an earlier post, there was a '1' in the scope settings that you posted. I don't know what this was. If it was 1v, there is a real problem. If it was 1v but you're using a 10x probe, that would make more sense and the actual vertical amp setting would be 10v, not 1v.
