Hahaha I’m not an admin here. And you deserved it! ;) Anyway, nice to see a familiar face (well, username!).

Wasn't there something very common missing on these like mA ability, just Amps ?

Full featured DMM's using this chipset have a fouth input jack: COM, V, mA/uA, A

AN8008 has three and is missing the low mA range, it has uA, high mA + A. So it reads:

0-99.99uA at the V jack with 100R shunt.
0-999.9uA at the V jack with 100R shunt.
0-999.9mA at the A jack with 0.01R shunt
0-9.999A  at the A jack with 0.01R shunt

Missing is the 9.999mA/99.99mA range with 0.99R shunt.

So you can only get 0.1mA resolution on mA measurements.

Also, it cannot measure past 9.999MEG ohms  :--

Yes. They don't have a range in the 10mA area. They jump straight from uA to A.

exe:
I like having only three jacks -- that's convenient for me. But I'd love to have an audible warning if plug not in the right socket.
