I found the other day that my Keysight U1253B was giving strange results, it was showing
a fuse was open when it was not, on checking the meter, I found that the "Negative" crocodile
was not making contact, it had been pushed in as normal ref the "Positive" Crock clip, I could get it to
maker contact by tapping the clip, so I thought that was that until it happened again, very misleading.
If I use the "Negative" probe no problem, has anybody else had this problem?
