AN8008 US $19, 9999count, 1uV, 0.01uA, 0.01Ohm, 1pF resolution meter
Mr. Scram:
I just received my second AN8008 and it seems to have taken 8 days. In both cases, delivery was ridiculously quick. Both came from the same seller. The serial numbers are only twohundredsomething apart, which doesn't seem too unlikely coming from the same source with only three weeks between them. What surprised me a bit is that the beep or buzzer of the new unit isn't by far as loud as the one of the first unit. I have taken them both apart to check for any differences, but there isn't anything visible that would explain why one is much louder than the other. The boards look exactly identical, with the lone exception being the oscillator packages that are installed rotated a 180 degrees with respect to each other. The hand soldered joiints don't seem to look as neat as the machine soldered ones, with some component legs having very little solder.
Calibration hasn't been checked. That will be something to do in the near future.

Cheap piezo buzzers can have quite some tolerance in them.

Did you exchange the test leads? Cleaning the tips of my 830 test Leeds with some sanding and alcohol made the buzzer louder.

It's not just in the continuity mode, but also when operating the switch when no leads are involved.

It’s a (surprisingly good) latching continuity mode, the contact resistance of the test leads has no relation to the loudness.
