AN8008 US $19, 9999count, 1uV, 0.01uA, 0.01Ohm, 1pF resolution meter

<< < (160/172) > >>

floobydust:
Would you add some gold test leads?
AN8008 always has an ohm or two of resistance, you can't even check 100R resistors to 1%.
It's like toy multimeter for measuring resistance.

I mainly use it for checking continuity in new PCB designs and other basic tests in my study. For this sort of thing it's prefect.

What am I doing wrong? (factory calibration, no modifications except extra cap to smoth dc-dc regulator's ripple as was suggested somewhere)

Those are my daily drivers (along with  K2000), while 121GW sits in the drawer.

PS There is always a lot of bias about cheap equipment.

I've cleaned the shit rotary switch a few times, tried various contact cleaners and lubes to prevent oxide from building up but it keeps happening. I don't use this DMM much.
Made in USA multimeters are my daily drivers for obvious reasons.

Update: CAIG DeoxIT F5 which has Polyphenyl Ether (PPE) totally works :) and the switch works without hassles now.

Interesting, I wonder if mine has different contacts and/or plating. I don't want to tear mine down yet because it works... I bought my dmms from aliexpress.

PS did you check your shunt with another dmm? Unlikely, but may be something wrong with it?
