It might happen more often than you think, with a 400mA fuse in a 60,000 count meter.

It depends..

Since I have DP831 and UT210E , i haven't measured current with meter that often.
When I do, I alternate between Brymens and MTX3293 (that has only one current input), and use Metrix for current measurements at desk mostly because of that. Which means I usually have no source to blow 10A fuse.

On equipment that runs lead acid accumulators, I mainly use UT210E, mostly because I don't need absolute precision and no need to disconnect wiring..

I blew exactly 3 fuses in meters in 40 years... First one, 40 years ago, scared the bejesus out of me.. Since then I'm really careful about any current measurements...  Other 2 were measuring current on equipment connected to lead acid acccu, that while measuring drew too much current..

I also pretty much never rotate meter switch with voltage connected, even if I know it's perfectly safe.. I just have bad feeling in the stomach when I think about doing it...  What can I say, childhood traumas....  :-DD

At least you don't have to then remove even more screws to pull the PCB to get at the fuses.   I tend to use other means to read current as well.   I've blown more fuses after I started looking at these handheld meters than in my entire life.   If a meter comes with glass, well, I can't resist watching them shatter.    :-DD

What's the relationship between the two?

If anything, 60,000 counts should make it less likely to blow a fuse because you can work more in the amps range.

Yes. Despite the price of HRC cartridges, I saw myself in the situation of occasional sudden spikes in current due to failures or shorts. All low-voltage electronics, but definitely enough to kill a 44/100.
