AN8008 US $19, 9999count, 1uV, 0.01uA, 0.01Ohm, 1pF resolution meter
Fungus:
Do the meters actually work differently or is it just a misprint on the range selector?
ciccio:
Reading Mark Hennessy post above they work differently, and from my post, my photo and the photos usually found about everywhere there are at least two different silk screens.
I think that what happened may be:
1) they design the correct multimeter with correct firmware and front panel graphics and they sell the first batch,
2) later, somebody make a mistake in programming a lot of said meters, enabling Hz and Duty Cycle on V position,
2b) they sell them , including one to Mark Hennessy,
3) customers complain and the Boss call Enginereing
4) two decisions are taken: a: program new boards with correct firmware and b: design and print modified panels for already programmed boards in stock
5) somebody in production mixes everything.
I've seen similar stories many times
Neytron:
My AN8002 measures frequency in the "VDC" position but only up to 99.99Khz (I do not know why!), to measure further I need to change to the Hz% position.
To add the Hz% function to the "VDC" position, write in the direction 0xAF = 0x12

The AN8008 "manual" (the folded bit of paper that comes with it) describes the difference between the two positions as "high voltage low frequency" and "low voltage high frequency". Presumably it's the same if enabled on the AN8002.

I received my Aneng An-8008 today. Since I am only interested in low\$\Omega\$ measurement and I didn't have an FRU handy, I checked with some low \$\Omega\$ resistors I had. Here is the result:
1R1 measured 1R13
5R1 measured 5R13
9R1 measured 9R18
All the resistors are 5% tolerance and I didn't use the OEM probes. I replaced them with a set of Frankie's Brymen leads. For my use, 15R is good, 30R isn't. The meter is more than capable. As I previously posted, this meter will never see voltage of any kind. If the device on site will not power up, because of SLAs, it will be immediately replaced and repaired at home where I have much better meters that aren't afraid of mains voltage. The other huge plus is the small size. It is about 1/2 the size of my Velleman meter. I find the stand is good enough, I can press the buttons without it falling over. I really like the back light. It is quite bright. The leads are more flexible than one would think for the price. They are almost as flexible as the Brymen leads. There was a difference in measurement with them, however. I only checked the 1.1\$\Omega\$ resistor and it measured 2.2\$\Omega\$. That was out enough for me. I never had any intention of using the original probes, Dave got me hooked on gold plated and I really like the Brymen leads, especially for the price.
