Mine arrived today. Ordered 1st July.
A few months back I picked up an AN8002, and have been quite impressed with it. But this is even better. This is a bit of an 8002-8008 comparison review, useful to anyone who already has the AN8002
If you don't already have either, it's worth mentioning that the case is hard plastic - no holster or similar. But it's light and seems to bounce well enough. A bit slippery on a hardwood bench. I much prefer the red of the AN8008 to the murky blue of the AN8002.
The AN8008 came with a bunch of accessories. The AN8002 didn't, but looking now, I see that they often do (though it adds a couple of £ to the price).
I can't image what use the square wave output will ever be. The AN8002 has temperature instead of square wave out, which is probably more useful. The square wave is fixed at 3V pk-pk. I haven't checked to see if that changes with battery voltage yet,
nor have I tried to determine the source impedance and Zout is around 2k. It appears to be AC coupled, or at least, it's symmetrical either side of 0V.
The AN8008 has a manual ranging button - the AN8002 lacks that (unless you take it apart).
The millivolt ranges are better than most - 10mV and 100mV. Resolution in the 10mV range is 1uV, which is very impressive for a hand-held DMM, let alone one so cheap. Looking at my Fluke collection, you need to stretch to a 187/9 for that.
Away from mV, the lowest Volts range is 1V (0.1mV resolution). For comparison, the AN8002 does 60mV (10uV resolution) and 600mV (100uV resolution) in mV, and the lowest range in Volts is 6V (1mV resolution) - the same as an 87V in normal mode.
They've fixed a minor "bug" that the AN8002 has. When pressing the yellow button in Volts mode, the modes are DC, AC, Hz and % - but according to the silk-screen, it's only DC and AC. With the AN8008, the silk-screening shows all 4 options. Not a big deal, but at least someone was paying attention to detail there...
The AN8008 has uA. The ranges are 100uA (10nA resolution) and 1mA (100nA resolution). The Fluke 87V can do 10nA resolution if you put in in hi-res mode. The Brymen BM235 only does 100nA resolution.
The AN8002 lacks uA. The milliamp range has 10uA resolution.
Both have a separate jack for 10A. The AN8002 shares the main Volts, etc, jack for milliamps. In the case of the 8008, the 10A jack also does milliamps, and the main Volts jack is used for microamps.
In A/mA mode, there are 2 ranges: 1000mA (100uA resolution) and 10A (1mA resolution).
The AN8008 uses a separate ICL8069 voltage reference IC. No sign of anything like that in the AN8002 - presumably using a reference in the main IC?
I've initially compared the two models to my BM235 and 87V, using various DC voltage references, and the accuracy of both seems to be very good indeed. Will be interested to see if they hold their calibration over time.
I've not had a chance to do more detailed testing, so those are first impressions only. Forgive any errors - it's late!
For £15 delivered, it's astonishing.
All the best,
Mark
