I did another test of the continuity on the AN9205A because I saw a flaw in my methodology on the previous one - by inserting the probe between the pins on the edge connector I was connecting with maybe two or three pins on the MCU - a big advantage.
This time I connected to a single pin and tried to beat the tester - and failed! I zipped so fast that the beep became almost too short to hear but it always flashed the LED (the LED is
much brighter IRL than it seem in the video and is really easy to see).
I zipped about as fast as I could and it never failed once. It's
not because I'm pressing hard, it does it with just the weight of the probe (see video). Who needs gold plating??

I tried the same test with mu Brymen and Fluke meters and they did OK but the bright LED is a big plus.
So.... I'm calling it, this is the best continuity tester of
any meter.

Edit: I measured the threshold resistance, it beeps below 48 Ohms.
