Which EEVblog episode discussed a bench DMM relay switching problem?

[ballsystemlord]

Hello,
I cannot for the life of me find this on yt. A YT'er, Dave, I'm sure, made a video which, in part, talked about a range switching problem where bench DMMs rapidly switch their relays thus causing them to wear out.

I'm interested in this content because I'm even now reviewing a DMM Dave hasn't gotten to and I want to properly test it for this problem.

Thanks!
