2+ years on my Keysight U1282A, got caught out in the rain yesterday and meter got a few splashes of rain, then had to totally strip it and clean PCB with isopropyl alcohol to get the thing to stop beeping for "incorrect lead" - current probe warning. I started out by cleaning out and drying the socket itself thinking that would be the source, but no joy until I stripped it and cleaned the PCB. Had completely forgotten its supposed to be IP67 rated.
Anyone else had fun with theirs in the rain?
