rscasny Younger me used to use them to measure contact resistance on high voltage switchgear (aka circuit breakers) and transfer switches. Older me uses it to measure rotor and stator winding resistance…

I can imagine them being extremely handy for measuring electrical contacts, such as relays to examine if they are failing, or for checking the resistance quality of shielding or grounding between different…

Interesting use! Maybe the inductance may be an issue, although some meters may be more stable than others. Presumably the industrial meters are more immune to that. Also, some meters may use a slow…

I've never used one. Once I had to check copper thickness on a prototype board and I used a resistance measurement (1A current from a lab power supply and measured voltage drop with a multimeter) to indirectly calculate the overall copper amount. I guess it would've been useful in that situation!
