I just received a 2465b and it seemed fine on my initial check. However, after leaving it on for several minutes, the readout and display started to drift up and down. At times, the top of the readout was off the screen.
I spent a few minutes searching but didn't find any other posts describing a similar issue. I'll keep looking.
I'm going to open it and check all the voltage rails and look for leaky caps.
Does this problem ring a bell with anyone? Any hints or pointers?
Thanks,
