Hello, I have a 577 D1 serial B030223 that appears to have developed a slight problem with displaying an IV curve

If you click on the link above notice the oddly displayed IV curve, I also included pictures of the instrument settings if that is questioned

Any one experience this issue before or have any thoughts, thanks
