Even the meters that work with narrow band sensors should be enough to show gross deviations in AFR.

I was involved in a serious discussion at Sharktoberfest with a non-Rennlist owner who is suffering from repetitive blown fuel pump fuses. Earlier car that has the ceramic fuses. Owner said that he'd found the end of a fuse welded into one of the holder tangs. Hard to find until he pulled the CE panel out. Replacement fuses were 'seating' in the leftover cone end rather than contacting the fuseholder tang directly. Extra resistance with high current flow was melting the fuses. This really points to the need to do some sort of contact cleaning on the early CE panels where the fuses sit. Maybe a soft brass tooth-brush would get the tangs clean but not remove the tin coating.
