The 'Official' AN8008 Meter Thread
« on: November 25, 2019, 06:03:50 pm »
I already own an Aneng AN8008 (also sold as the ZT109) and it's a pretty useful meter.  I saw one today on Amazon for $6.49 US (+$2.99 shipping) and I couldn't resist (I've paid more for a beer) so I bought it. As expected it says it won't arrive until December 17 - January 9 so clearly it's on a slow boat from China, perhaps on a camel along the silk road?  See the picture, it's not actually got 'Aneng' on it but it does have a cool black case.

Let's use this thread to come up with all the things we can do with/to an AN8008.

1. Calibrate it, my instructions on how to do that are here.
2. Dave's done a video review which I've put at the bottom - I concur with Dave, the Cat ratings are quixotic, BE CAREFUL!
3. Fuses are 3.6 x 10 mm and can be purchased here...(can someone give me a link?)
4. Someone has done a fuse upgrade here (still looking for it)
5. Stability can be increased by adding Caps to reduce ripple on the power supply; check out this link.
6. Russian website that covers most aspects of hacking the flash memory (use Google translate)
7. Accuracy is pretty good except for low current (2-30 mA AC). This post gives typical results.
8. Setting to hack the eeprom to add Temp to mV range is here.
9. Kerry Wong's English website on DTM0660L-based meters and how to hack the eeprom is here.
10. Price ranges from $6.50 to $25

Send in your ideas (note: suggestions for uses as an alternative to a rodent will likely be rejected).

It looks good until you see the UT139C that retails for over $90 going for $9.69 with free shipping as well. No thanks. Looking forward to your notes on what shows up on your doorstep though. In fact, why not get the alleged 139C as well and do a head to head test?

Earlier this year, I bought a 17 dollar ut139c  on Amazon. No uni-t logo, but comparing to posted photos it appears to be the real thing. Works great too.  I paid $24 for my AN8008. The ut139c is the better meter, but the an8008 is easier to carry around in my backpack on the rare occasions I need take it along. Each has it's place.

So your link brings up a UT139 meter priced at $70.79, where can you get it for $9.69?

I got a 'your item has shipped email' very shortly after I placed the order for the AN8008.

Has anyone figured out how to give the AN8008 serial communications?

There was 1 at that $9.69 price. Someone got it (anyone here?). I should have screenshotted it, but wasn't that interested. It was there when I posted.

I have a ZT109 with no sticker actually calling it an AN8008, nothing printed but the CAT rating (!). I got it about a year ago when someone was offloading a pile of them for eleven dollars shipped. I read that the AIMO process meters might have been the same sort of thing, rejects or factory seconds or whatever. My ZT109 has a sort of warping of the casing that wouldn't have allowed the branding sticker on the top left to lie flat. That might be the only reason it was discounted and abandoned by the would-be badger. Hope so, anyway.

I was interested enough that I bought a few of the Zotek meters, and I preferred the ZT109 to any of the others. It almost qualifies as a pocket meter-- an enterprising mind could certainly make it so-- and mine seems accurate enough. It's sort of fun, but my other meters are bricks, they feel like tools. This is, well... it's portable, it measures very low voltages. It's certainly worth what I paid for it, not that I use it often since getting a Simpson. Measurements are just more fun chasing a needle reading the scales, even if it can't claim the precision of the little red bug from the long boat.

Hey, I noticed your AN8008 appears to have a black case. Trade ya.  :)

Dream on Johnboy!

Given that the unit name is blank (at least the picture shows that), maybe I could invent my own meter brand name like ACME?

I am presuming that, for $6.49, this is a second/reject but I will do whatever upgrades are necessary/possible on this one.  I understand that temperature is one that can be done with a chip reprogram.  Again, if you can help out by giving me the links to the appropriate content, I'll edit the first post to create an AN8008 index.

Same here.It was sold as DM139C and it is the real deal as I put it through its paces including slapping it to a high voltage source on the non-volts ranges.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

Hmm, the black AN8008 I 'purchased' for $6.49 may be a scammer sale.  The China post tracking says the tracking number that was created on Nov 25 is unknown.  Seller was Mootea310

A few months ago I had a similar price for a AN8009 that didn't materialize. It was from eBay, though.

I personally wouldn't pay the current regular price for the AN8008/8009 - there are better meters out there, but YMMV.

Nope. Not when you can get an AN860B+ for the same price (and an AN870 for $5 more).
