AN8008 US $19, 9999count, 1uV, 0.01uA, 0.01Ohm, 1pF resolution meter

[kalel]

Forgive my naivety, but what's wrong if it comes from China? Mine took about 2.5 weeks, but no problems so far with the meter. just no box.

Some people want it NOW, DAMMIT!

The more you want something, the more impatient you are. On the "bright side", if it takes more time to arrive, you might be even happier to receive it (if everything goes well with the package and meter). Generally it is easier if things do arrive quickly. I wouldn't pay more, however (maybe a very small reasonable difference).

That said, I'm glad you recommended the AN860B+. Not that bigger is better in this case (smaller is more handy), but I do like the added functionality.

i get banggood stuff in under 2 weeks, maybe belgian customs/post is sitting on it to create extra delays.
use the tracking number next-time to see.

Belgian customs are slow but in this case since it is less than 22€ it bypass customs actions.
From time to time I get stuff from China in less than 2 weeks.
I track every days what I order, in this case it is just indicated “China, Departure to country of destination”

Banggood is a Chinese vendor that typically delivers to me, in Michigan USA, in 2 weeks or less; I use them a lot and would recommend them.

My annoyance was that, as an Amazon Prime customer, where shipping is free, I'm used to seeing an item listed as 'Prime', clicking on it, and having it a less than a week later.  The Prime price may be a couple of dollars more but with free shipping that is often the better deal.  When I went on Amazon to buy the AN8008, I clicked on a Prime vendor for about $23 and then waited a month to get it.  I could have paid less to order it from Banggood (or an eBay seller in China), and got it in 2 weeks.

I don't mind buying from China but I do mind buying from Amazon, probably paying a few dollars more, and then finding that the item was shipped from China and took a month to get here.

That's exactly what happened to me, not sure how that supplier got listed as "Prime", I pay yearly for that 2-day shipping perk. As someone hypnotized earlier in this thread, they 1st shipped me a dollar item with a card saying the meter would be shipped later. I waited two weeks just for that "free" gift, then a few more weeks to get what I really ordered, the meter. I reported this to Amazon, I hope these mini scams don't get popular, I'll try and be a lot more careful from now on.

[Gandalf_Sr]

MacMeter, yes, I too got the prophylactic for remote-controls, I guess if I ran a pay-by-the-hour motel, they may have been useful... but Ii don't... and they aren't.

But now I have me AN8008 and all is right with the world

AN8008 CALIBRATION BASICS
I've figured out how to do calibration although I don't have the finer details worked out.  Here's what I know...

1. Short out J1 on the PCB (it's at the top right corner as you look at the PCB from the back of the meter)
2. Get your calibration reference ready and connected - in my case a 300 mA DC feed through the mA/A terminal and Common
3. Turn rotary control from off to the resistance position and CAL will appear on the display
3. Now WAIT until you hear a beep and then move the rotary control to the mA/A position - if you turn the rotary control away from resistance too quickly it doesn't show the values you've selected but moving the rotary switch around corrects that
4. Press [Set/Hold] (orange) button repeatedly until you see DC mA and a value will be displayed
5. Now you should see a value close to what you're providing the meter with, around 300 mA DC in my case
6. Press the [Range] (blue) button (quick press) to range down (but it only does it in 0.1 A increments)
7. Press and hold the [Range] (blue) button (long press) to range up (but it only does it in 0.1 A increments)
8. Press [Set/Hold] (orange) button to move off that setting (I think this is when the cal change just made is saved)
9. Move the rotary switch to off
10. Clear the link on J1 and power back on and test

As far as I can tell, the trick is to set the input to an exact value like 300 mA so you can set that value on the display during cal because you can't adjust the display to 303 mA so, for my slight discrepancy, I saw 298 mA displayed, I ranged down - I saw 200 mA, and then ,with a long press of [Range], ranged up and then I saw 300 mA displayed, pressed the orange button again and I was done.  Other parameters can be set by pressing the [Set/Hold] (orange) button repeatedly but you'll only see values corresponding to the rotary position selected so you'd leave it in the resistance position to cycle through the measurements associated with that position including resistance.

What I'm not clear about is when it actually stores a new calibration value, I guess that, once you use the [Range] (blue) button, it changes the calibration for that setting, and I think it saves it when - having got the display to show the value you want, you press the orange button once more. 

At first I did my above procedure providing 300 mA but ranged down to display 100 mA  and couldn't change that value because I hadn't figured out that a long press ranges up by that point.  So when I then switched off and removed the link, it had calibrated the meter to display 100 mA when 300 mA was supplied which it did.  I had to re-calibrate after I figured out that the long press increases the displayed value.

After I posted a video where I had modified the KZ102 (AN8002) to the capacitance readings were off about 100pF.  Someone had wrote me about modifying the contents of the PROM to realign it.   Seems like a lot of work.  Does anyone know if the above procedure applies to the AN8002 (and others) as well?  For capacitance and current, what are the standard values that are required?

Prime is irrelevant. Please tell whether the item was listed as "In stock and sold by Amazon" or "Sold by X and fulfilled by Amazon"?

If either of those were stated and the item was not promptly packed and shipped from an Amazon warehouse you have a complaint against Amazon for false listing information.

i imagine it's the same, the newer chip is evolved from the DM0660

great video btw, after watching your mods i had to open mine again.
not for electronics, i never thought to grease the switch detents the first time - very nice positive action now i put some lithium grease in it! 

[ModemHead]

This "Ragu 17B+" was very recently brought to my attention.  $10 at Amazon, with Prime 2-day shipping available.

I do not have one.  But by looks alone, I'm guessing this is another DMT0660-based meter somewhat like the AN860B+, trading the temperature function for non-contact voltage.

Sure is cheap!  Not sure how long the sale price will last.

Looks good. Might get to $20 or so.



Couldn't find it on eBay except from 2 US sellers, $14 and 26 without shipping.

Ragu: Makes me think of spaghetti.

And the 17B+ makes me think of copy pasta.

Pasta with ragu. omnomn

Don't forget a warning - there are two steel balls and spring in the rotary switch detent, if you take it apart to lube it the balls want to shoot across a room! 

[edit: there's two of them!]

[stj]

yes, good warning - there are 2 actually, but i released it nice & slow.

I got more than 2 sellers but they were all from USA or UK. No Chinese.

I wonder if it's a rebrand.

It might be a good deal for those in the US. Especially at the Amazon price.
But of course it's difficult to tell anything unless someone was to take it and make a review.

[b_force]

Got mine on Banggood and took only 1.5 weeks to arrive for only 15 euro.

It was a Santa Claus day today 
It finally arrived and got my Infiniium scope as well

This might depend on whether or not a person in this situation already has a scope.
If not, a scope might get more attention at start as it's something new to learn how to use, explore, and hopefully avoid damaging with improper use.

Now, if someone was to get their first multimeter and scope at the same time (I'm sure this doesn't happen every time), it would be interesting to see which tool is more fun to explore.

Yep 

Tomorrow Santa is coming again and will bring me the calibrator that was sleeping 3 weeks in customs

Ten clams for a 6000 count True RMS  ... holy Bleep!ing Bleep!crackers!!!

I couldn't help m'self... I had to get myself a shiny red spaghetti meter, even though they're evidently not going to be back in Amazon's Warehouse until 9/10-9/12 or so; no matter what delivery option I chose it was "Delivery by 9/14". So I picked the "No Rush" option and got $5 to spend in Amazon Pantry... probably get me some BBQ spices or somesuch.

This is getting down to the realm of the Horror Fraught "Drop Dead Red" little boxes of Damifino with test leads on 'em I used to get for free just so I could give 'em away. 

One time, they had a month-long thing going with a new special item every day; every time I brought in the freebie coupon for one of those meters, sometimes from both stores in my neighborhood if teh special of the day was a really good item. At the end of the month, I donated a box full of 'em to my Model Airfield to give out to members who needed a meter.

Did I get something on my shoe?

Spaghetti meter, but no pasta? No spaghetti sauce? Missed opportunity.
