The used probes could make a difference too, the fastest results I got with the gold plated probemasters.
But out of genuine curiosity, I'll ask:
Why does it have to be "super fast" ?

I always just listen to the beeper. If it starts to sound intermittent then it is either bad contact from the probe or there isn't a short. If there isn't a full short then it needs further investigation. My typical use for continiuty is to check connections between points, check fuses and find blown up MOSFETs / diodes. In some cases I sweep the probes across a row of pins quickly and listen for the DMM make some sound. A short blip is enough. BTW I use sharp, hardened steel probes from Hirschmann or a similar A-brand.

Found a test:


--- Quote ---Continuity speed is moderate (About 100ms).
Continuity beeps when resistance is below 30ohm, this is adjustable from 0 to 2000ohm

0.1sec...Should be fast enough.

 ;D i like throw the wrench in that smooth process of choosing bench DMM

and offer to buy 3 ( YES 3 of them) for a price of one strange looking thingi
https://www.ebay.com/itm/175521881649

benefits : multiply points of measure to better understand what going on ;   it will defininutly looks like a pro ;  devices good and have some logging feature; finally girls really like it,  as it looks like a rocket scientist.

sorry been away had lots of doc stuff past few days and a minor surgery i had to have to remove a small tumor from the liver.

anyway his budget is up to maybe 4-500 he wants this to last a long time and not have to buy one again for a good while (though imo once he catches the bug ill bet he ends up buying more like most of us) and he was offered a brand new hantek 3055 in the box for 400$ even which for that unit seems a good deal but they dont seem to have a great rep around here. sdg reviewed them and liked them.

but i also thought he should spend maybe 200 or less but he is set on something a bit higher end then that to last for a while and he is looking at 5.5 digits. i told him he really doesnt need more then 4.5 but he wants at least a 5.5 (he wanted a 6.5 till he saw those prices new lol). not really sure the hantek would be the best choice but then im not sure in that kind of budget what would be. that is his max for a bench meter though im sure if he found something as good for less he may go that way. but he does want a new one not second hand (im not sure why but he def wants something new)

GigaJoe:
"hantek 3055"
im no doubt it will work and shows numbers ,   but when i watch this video  -  ;  it seems period of measurement was 4 seconds . cheap ADC with averaging to get 1 more digit ...   -  for me personally 4sec of averaging - NO WAY ... ;
second thing - when it drift alot  in a time,  and it will , due to components - no one will help , as the process of adjustment unknown. no support , no firmware update
 
siglent would be more reasonable ; 

PS - I do remember Hantek skope that constantly freeze - throw away money.
