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

<< < (42/172) > >>

If anything, skipping the amps range would make more sense to me. Circuits where you need both µA/nA and µV are unlikely to need amps ranges. The exception might be HVAC, but for some reason this does not strike me as an HVAC meter ;).

I guess they wanted to claim 10 nA to 10 A in their marketing material.

I like all your answers, they explain many things.
But, IMHO the strongest point of this $19 meter is 1uV resolution, not any of his Amp range. No need to discuss Amp ranges so deeply.

The vast majority of electronics works on mA, not uA.
This meter fails to cover the most common current ranges in electronics design with any degree of decent resolution.

Maybe they're planning to release another one in a couple of months* with 10mA range and temperature. 

Double the sales! :popcorn:


(*) Or after the sales of this one die down.

I'm with Dave on this one, I'd much rather see the 10A range replaced by a usable mA range.  Can't this meter be hacked to do that, maybe with a shunt resistor change?

alm:
Sure, if you spend another $20 on a new shunt :P.

OK, the challenge has been made!  All I have to do is wait for my meter to arrive on the slow boat from China...   :=\

[EDIT]  What's the resistance of the 1A shunt?  If it was 0.001 Ohms then I'm thinking it would be way less than $20 for a 1 Ohm 0.1% resistor.
