I hesitate to even post this for fear of “jinxing” it, if it is indeed true that is. Big Smile LOL

I started with ordering 1 of the UNI-T 210E, but before I hit Check Out I added one more to give my friend. When I did that it gave me the Free Shipping option thru ‘Priority Direct Mail’… whatever that is. Smile

Well according to the order status, from time of order until the time it shipped was 6 hours 3 minutes 6 seconds.
I was pleasantly shocked to say the least……………

Now I realize the carrier still has to receive it and it is many miles to South West Alabama… but IF things keep going this way I’ll be a happy camper. Wink

Never mind, this was just wishful thinking……… Big Smile
Tracking is so confusing to me I can’t tell if it has even left China yet. LOL ….

EDIT___ 23 April 2016 / 1120 hrs.
Mine arrived today. Ordered 6 April, arrived 23 April. Sent by way of Priority Direct Mail. Not to bad at all. Smile
They were packed reasonably well and arrived damage free. Batteries were installed in both.
I have not had a chance to test them yet but they both power up.
I am pleased at this point for sure.
Thank you BangGood!

Oh yeah, the funny thing was the instructions are all in Chinese…… I guess it’s “Chinese”?????
But this will fix that minor problem……

I appear to be measuring exceptionally low. 1.9A on a 2.8A 105c driver. 2.3A on several different FET drivers with a high drain cells. Worse than my stock 22awg DMM leads.

Just to be sure: did you notice that your meter starts on AC? And that you have to switch it to DC before you can measure the tailcap current? From where I’m standing, there is size wise nothing wrong with your loop. It is thicker and shorter than mine. On my clamp-meter I measure over 1 Amp more on my BLF A6 than with my DMM (with home-made leads almost as thick as my loop).

Edit: sorry, a bit slow. About your last entry, I “wiggle” the dial a tiny bit before I start measuring. I know it is kinda stupid to explain but I’m under the impression that it “sits better in the click” that way.

I always think long and hard before I say something really stupid.

I forgot to update my post. I made a dumb with the first version of my loop. There wasn’t enough contact surface to ensure a solid, consistent connection. This is where most of the variance was occurring too.

Since then I sanded the ends down, soldered them together, and resanded up to 1500grit.

I then made a second loop out of 12AWG silicone wire (my old dmm leads that I really didn’t want to chop up, sentimental maybe?). Soldered both ends of the 12awg and sanded the ends flat until copper showed and went up to 1500grit.

Both loops show similar measurements so I’m happy now. The solid 14×4 is much easier to use since it’s.. Well.. solid. Silly

I’m seeing 10.55A on a 4.13v 30Q in the old xpg2 triple. 2.76A on a 2.8A driver constant and consistent.

Not perfect, but good enough for now. I may try something different down the road.

Can anyone try this to see what you get:
- grab one LiIon cell
- switch uni-t to voltage reading
- press blue buttone to switch from AC to DC
- then press gray button to zero out the displayed value
- then try to measure cell voltage

I get “OL” as overload!

Yep, I can repeat that with mine.

If you don’t zero it (not that you would need to, reading V) it works fine.

Yes, noticed that, or if you long press Zero it will return to Auto and measure as it should.
I was pressing Zero because numbers were jumping all over the place but now I noticed that this happens only while I am moving the probes, if I stop moving them display settles to 000.0

Still waiting for my clamp meter. It will probably arrive sooner or later, but all I have is a fake tracking number that doesn’t belong to any courier or postal service.

A couple weeks. Still earl days, but the fact that I don’t really know if there is one in the mail is a bit off putting.

Mine arrived today. Works great. Nice little case. I didn’t expect that. I was also surprised to find came with batteries installed.

I wanted to buy another one for a friend but the 210E has a different page on the shop now (the older page is still there but it says “out of stock”)… so the code is not valid Sad do you you know if it’s still possible to buy it for 28 USD?

It’s already restocked actually (also the price is very similar) but the url is different so the code is not valid: http://www.banggood.com/UNI-T-UT210E-Auto-Range-True-RMS-Clamp-Multimete...

Low ohm precision current shunts are low cost: Precision Low Cost Current Shunt Resistor

Digikey has a postage shipping method that is inexpensive at least in the U.S.
