ANENG AN8001, 6000 count true RMS Multimeter for $14.
« on: November 16, 2016, 05:16:58 pm »
Has anyone seen or better yet have one of these http://www.ebay.com/itm/Digital-Multimeter-6000-counts-Backlight-AC-DC-Ammeter-Voltmeter-Portable-Meter-/192021771043?hash=item2cb563b323:g:IhsAAOSwal5YIVhS

It looks like it is brand new, no reviews or any reference to it on Google.  Almost sounds too good to be true for $14 shipped.  What I like about it is that you can perform all but the 10A measurement without switching leads.  I am NOT very careless but still I go through fuses after measuring current and then trying to measure voltage without switching leads.

I found it also on Aliexpress with a couple different names and model numbers with more detail specs.  Aliexpress search sucks, so the best way to find it there is to search for, 6000 count Multimeter.

Look at this thread
https://www.eevblog.com/forum/testgear/almost-a-fluke/

reply 22 onwards.

Looks like a cheap chinese DMM, what Dave would call a 'one hung low'
Avoid if you plan to do any work on live mains electricity (even just the occasional check for mains!)

Doesn't look to bad. Of course someone will have to buy one for us to know more about it.
I'am curious to see how it stacks up to the 830 variants.

I'm really not a fan of DMMs that share the mA ranges with the Voltage inputs. To my mind it's far too easy to accidentally short the input and show up any weaknesses in the input protection and fusing. Obviously it's less of problem for low energy circuits than its stated rating, but nuisance fuse blowing is still an issue.

Since it's build similar to VC921 (TrueRMS variant) it should survive 1000V on resistance, continuity, etc. (unlike dt830) http://y2u.be/QNRFTMk8MVI

If you want most features of DTM0660 chip and don't care above 1000V CAT II search HP-890CN for $20 on ebay. Similar to Gossen MetraHit, $20 HP-890CN will prevent you from using voltage mode with test leads connected to current jack.

If you want DTM0660 with PTC/MOV input protection search Uni-T UT139C.

If you want DTM0660 with PTCs+MOVs+HRC fuses, search Tekpower TP40 for $36 on amazon.

What's a good place to get them for that price?  I didn't find anything below the $14 eBay listing.

That's good to know! I was hoping that would be the case. Thank's to DTM0660's digital adjustments, hackability and cheap price, meters based on it are great for hackers who like to bre.. modify their tools.
I'm looking forward to seeing more and more cheap meter based on that chip.

Two AAAs? Awesome! I ordered one (labeled RM101) and at that time description said it uses 9V batteries. I wen't and checked the description again and it indeed has been updated... 2xAAA it is!
Great set of features in small (Fluke 101-sized but 5mm thicker, if specs don't lie) non-pocket multimeter.

Those fuses, though. What are those? Fuses for ants? It's good thing they exist and are in correct traces, but they look like baby fuses. 3.6mmx10mm  :-//

Hmmm, the only thing genuine about that 600V Cat III rating is the ink it's printed with.  :palm:

It's fine to sell a cheap multimeter for low voltage, low energy use, what's wrong is to deliberately lie about it's safety rating. Given the mA range on the voltage terminals and the tiny fuses, there's a reasonable risk of putting them to the test. There's no way I'd let that anywhere near a mains supply. Probably perfectly fine for breadboard use though.

Pretty decent for that price, order of magnitude better than any 830 and similar.

I think they're 3.6x10mm form factor. Looking at a Littlefuse part with axial leads but otherwise similar specs it's interrupt rating is 50A at 250VAC which I'm not sure is even good enough for domestic mains work.

Now that 9V Li-ion batteries are available cheaply, I would actually prefer 9V to AAA.

It's fine for those of us in 120VAC countries.

And what the point? There is no capacity advantage of cheap Li-ion over AAA eneloop (low discharge). High capacity Li-ion is costs the same or more than the meter itself. Also it would make the meter thicker.

Li-ion 9V: 8.4V * 600mAh = 5Wh
Eneloop 2*AAA: 2.4V * 800mAh = 1.9Wh

I have been paying $3 each for 9V Li-ion, compared to $2 each for AAA eneloops, so the Li-ion is cheaper.
How much do you pay for AAAs?

Also, the self discharge rate of the Li-ion is even better than eneloops, which is nice for a meter that may not be used often.

Let's have a look at eM860T for example http://www.kerrywong.com/2016/03/13/quick-review-of-the-ennologic-em860t-true-rms-multimeter/
It uses linear voltage regulator to drop 9V battery to 3V, so you should look at A*h instead of W*h.

DTM0660 require 2.4V ~ 3.6V, so using 9V battery in DTM0660 based multimeters is wasteful. Couple AA would have four times more mA*h than 9V battery.

I just got one of these ANENG AN8001 meters. I stumbled across it a on EBAY a couple of weeks back and was interested to see how it compared to the little FLUKE101. There's plenty of teardown photos in the previously posted links so there's no need for me to post any photos of it.

Sizewise it's pretty much identical to the FLUKE101. The AN8001 is a little bit lighter and overall it feels a bit cheaper but then again, it's $14.

Mechanically it feels fairly solid, not quite as rigid as the FLUKE101 but certainly not bad in comparison. The input jacks is not nearly as solid as on the FLUKE though. The AN8001 does have a tilting stand (which the FLUKE101 doesn't) but it's quite flimsy and you really can't push the buttons with your index finger without the meter falling over. But you can easily support the meter with your fingers and press the buttons with your thumb - which I tend to do anyway.

The range switch is fairly snappy with distinct positions but you CAN (ie, if you try to) easily position the knob between two positions. You can do that on the FLUKE101 as well but not quite as easily.

The digits are about 50% bigger on the AN8001 compared to the FLUKE101, which I like. The viewing angle is really good side to side and quite good looking at it from the bottom (ie with it lying in front of you on the bench), it's not that great looking at it from above. The FLUKE101 on the other hand is about the same (really good) all around. The AN8001 does have a backlight (the FLUKE101 doesn't) which is fairly uniform with a bit of a hotspot on the right hand side of the display (where the LED obviously is). The viewing angle, with the backlight on, gets a whole lot worse. Side to side it's still quite good, from the bottom it's OK but you start to see the unlit segments but pretty much anything "beyond" straight on and the digits just disappears.

The continuity buzzer on the AN8001 is MUCH better compared to the FLUKE101. It's latched (so is the FLUKE101) but the AN8001 is a lot faster, probably on par the FLUKE189 etc.

One thing I don't like with the FLUKE101 is the autoranging. It's fairly slow and it keeps bouncing numbers and decimal points across the screen as it goes thru the ranges. The AN8001 isn't much (if any) faster but at least it seems to blank out the digits, does its thing and THEN come up with a number. I don't know, perhaps I'm being picky.

I did a couple of comparing measurments between the two (and a FLUKE189 acting as a "reference"). On the ranges where the 189 has more resolution I've rounded the numbers off to display the same number of digits.
Code: [Select]
------------ DC MILLIVOLTS -----------
FLUKE189 FLUKE101 AN8011
50.26mV N/A 50.31mV
200.3mV N/A 200.3mV
600.5mV N/A 600.4mV
The mV range on the AN8001 is weird. When disconnecting the leads the display value jumps up and then very slowly (as in minutes) bleeds off. Switching ranges back and forth clears it. And re-connecting the leads "instantly" displays the "new" voltage.

Code: [Select]
-------------- DC VOLTS --------------
FLUKE189 FLUKE101 AN8011
 2,499 2,510 2,498
 4,999 5,023 4,998
 7,50 7,53 7,49
10,00 10,04 9,99

Code: [Select]
-------------- Resistance ------------
FLUKE189 FLUKE101 AN8011
10.3 Ohms 10.3 Ohms * 10.2 Ohms
14.93k 14.93k 14.93k
1.048M 1.049M 1.046M
* After it's initial autorange dance the FLUKE101 settles on 10.9 Ohms. Then over a period of maby 5 seconds it creeps down to 10.3 Ohms.

Code: [Select]
------------- Capacitance ------------
FLUKE189 FLUKE101 AN8011
2.35nF 2.25nF 2.27nF
19.8nF 19.50nF 19.70nF
10.85uF 10.72uF 10.82uF

I haven't done any measurements on the ACV or current ranges but if anyone want's to see that, or anything else for that matter, let me know and I'll see what I can do.

Disclaimer: I've only played around with the meter for a couple of hours and I've had the FLUKE101 for a little while longer but to be honest I like the AN8001 more than the FLUKE101. The weird thing with the mV range bothers me (so does the weird thing that the FLUKE does on the Ohms range) and the lack of proper input protection and those tiny fuses means I will not stick it across the 3-phase power comming into the house. The FLUKE is good in that regard since it doesn't even HAVE a current range and it DOES have proper input protection.

The mVDC range on the AN8001 is high impedance, as opposed to the usual 10 - 11 meg, which probably explains the odd behavior.

I'm even more impressed by the advertised specs/price of  this Aneng AN860b meter on eBay

If the specs are to be believed, for $23.36 shipped you get TRMS, Current to 20A, Frequency to 20 MHz, Duty Cycle,  Temp, Min/Max Hold,  a large backlit display, along with the usual measurements.   

Are these Aneng meters new? I've never seen a review of one.  It's impressive what's coming out of Shenzhen these days..- at least for "low end" stuff.

I bought two PM18C and two HP-890CN last week.
The PM18C DC voltage calibration is excellent, absolute error is just 1 count off in the worst case, much better than the HP-890CN calibration (one of them is off  by a few counts in DC voltage range).

the continuity mode is good with no scratching and it latches. I like it and for $14 you can go wrong. If you want to see what it looks like and how it works then take a look at my youtube video.
