Most older DMMs. Modern ones synthesize a steady or intermittent tone in response to steady continuity. Older ones just use an instantaneous voltage threshold, which is much better for diagnosing an intermittent connection than the newer style, where the tone generator inadvertently does so much time averaging as to be useless outside steady state.
I keep a 30-year-old Triplett around more or less just for this reason. My Fluke from 2019 is much better at everything else, but...

I specifically reached for the old, analog Simpson since it was much easier to see the needle jump than trying to watch for the small digital screen to move with all of its delays.
