AN8008 US $19, 9999count, 1uV, 0.01uA, 0.01Ohm, 1pF resolution meter
texaspyro:
I did a few quick checks on my units. Voltage was dead on (I checked mostly in the 1.0 .. 10V area) using a Valhalla DC calibrator and a Fluke 732B. At 5V there was a 1 mV offset when swapping the lead polarity.
Frequency was dead on at 5 and 10 MHZ (HP-5071A cesium beam oscillator). Counter goes to at least 20 MHz (limit of the pulse generator I had handy).
SR-104 resistor was dead on at 10 K. Readings of a ESI DB877 decade box were pretty much spot on. Lead resistance was 0.06 ohms. The meter takes a few seconds to settle to a final value.
Capacitance agreed quite well with a Genrad 0.1% decade box. it would be nice if you could null out the lead capacitance...
My current and AC calibrators were in use elsewhere, so I did not check those.
All in all, not to shabby for a $15 pocket meter. From posts in this thread, the only real wart on these meters if the low milliamp readings. I'd like to modify my eeprom to add temperature and turn off the backlight timeout.

there is still a lot available on ebay btw.

I'm sure there's a lot of eBay sellers who'll be happy to take your money then go down to the Shenzhen Market to see if they can find one, yes.
Can't find one? Never mind, the customer can wait a few days, just blame it on the postal system... :popcorn:

If you want fast shipping, simply don't order on Ebay/overseas. :-//

It's almost as if you haven't been reading the last two pages of this thread... :-//
But yes, I'm sure one will turn up eventually if you order today.
