content: Hi, recently I saw new meter on ebay - less then half the price of UT61e, 1uV instead of 10uV resolution, interesting.http://www.ebay.com/itm/AN8008-True-RMS-Digital-Multimeter-9999-Counts-Square-Wave-Voltage-Ammeter-/282496420913?epid=0&hash=item41c6194c31:g:7SAAAOSwi7RZKRTdAlthough without logging..Who will be first to teardown?

content: Is that a new model of those cheapo meters?Looks intriguing, does it have a square waveoutput?Update: Yes it does - read the description (duh!)QuoteThe AN8001 has been analyzed to death here, I assume it's quite similar inside.https://www.eevblog.com/forum/testgear/aneng-an8001-6000-count-true-rms-multimeter/

content: It has a uA range, which the AN8001 is lacking. And 9999 counts.I bet all the people who rushed out to buy the AN8001 a few months ago will be upset by that.

content: Quote from: Wytnucls on June 29, 2017, 01:10:48 pmYep.I was thinking about getting an AN8001 for Arduino club but lack of uA bothered me. This is much better, I might have to take the plunge.All the review videos show decent autorange speed, fast continuity test, etc. It even does true RMS up to 1kHz and comes with lots of accessories and a bag.

content: Regarding safety: The AN8001 was badly designed. It has an "OFF" position right next the the "mA" position. I bet the person who put in two "OFF" positions thought he was being clever, but...In this new AN8008 the "OFF" position is far from the low impedance ranges - which is as it should be, especially for places like Arduino club.

content: Quote from: Wytnucls on June 29, 2017, 01:46:53 pmThe 121GW doesn't share the mA socket with the V socket, but yes, it's still bad design. Even if the leads are in the right place you have to switch past a bunch of other ranges (eg. Ohms) to get to the voltage ranges. Not ideal if the leads are connected to something at the time.Comments, Dave?

content: Quote from: Fungus on June 29, 2017, 01:57:22 pmI like having the 2nd OFF position. Having only one in the traditional position makes your meter Voltage range racistIf you do a lot of current measurement then the right hand off position can be handy.Of course you can simply ignore the extra OFF position if it bugs you or doesn't suit your usage.I kinda like the look of this cheap meter for basic budget low level electronics work, but if it's like the 8001 inside then it's your typical cheapie, albeit a bit more useful than most with those extra ranges.

I'm not sure what I'd use the square wave output for though.(Can it flash a LED? Will it make a speaker buzz?)Quote from: EEVblog on June 29, 2017, 02:20:07 pmMe, too.

content: Nice, addition of uA makes it a lot better. I bet it will still have those silly little 10mm fuses though :-/ I ended up buying leaded ones from RS and cutting the leads off.

content: casinada beat me too it, but following the info from the 8001 thread (https://www.eevblog.com/forum/testgear/aneng-an8001-6000-count-true-rms-multimeter/) and searching kazus.ru for 8008 gets us to this thread (http://kazus.ru/forums/showthread.php?t=112135) which mentions it as the Zotek ZT109 / Aneng 8008 / Autotool DM700 as what appear to be the most recent ones added to the listQuote from: kazus.ruIt seems it has been around since at least mid-may when this post was made :http://kazus.ru/forums/showthread.php?p=1122373This post I think has the EEPROM dump from the 8008, google translation isn't so helpful "By the way, since the speech went for innovations, I can say that the AN8008-go (ZT109) on the arena all the same. And the problems of 9999 are also present, but there it is possible to select ranges manually."http://kazus.ru/forums/showpost.php?p=1126917&postcount=1827First couple posts in this pagehttp://kazus.ru/forums/showthread.php?t=112135&page=184I'm not quite grokking the machne translation totally but I think they are taking about some issuesNote that the temperature mode is not enabled, it needs to be added by reprogramming the eeprom.Teardown photos on this post are of the 8008http://kazus.ru/forums/showpost.php?p=1127606&postcount=1854
