Groupbuy for UNI-T UT210e clamp meter for tailcap current readings

According to the product description, it should. AC and DC Voltage, Resistance / Continuity, Capacitance, Diode forward voltage are all there.

Also listed are NCV, which I think is a Non Contact Voltage sensor, meaning that you can wave it near a wire and it beeps or displays something if voltage is present and “V.F.C.” which I have no idea what it is.

correct.
From uni.-t site V.F.C function is for measuring signal at variable frequency

I copy-pasted the specs of the UT210E plus the specs for an other decent UNI-T meter costing $27.43 (Fasttech)
It looks like it does the other functions well enough to use it as a general multimeter.

Thanks djozz, you are obviously smarter than I am (check the manufacturers website, not the supplier - why didn’t I think of that! :party: (< dunce cap, not party cap.))

I have now pulled the user manual and found that this meter does not appear to measure frequency or temperature. I’m ok with this, as I have another meter that does this for me, but if it is important to you for what you need it to do, this is the wrong meter.

Just seeing this now.
Is this buy still active?

Eehhm, I must admit that I did not copy the manufacturer's website, but I took one description from Gearbest, the other from Fasttech

Rereading your post, I don’t know where I got the idea that you pulled it from the Manufacturer site. But your post DID make me go there, so I STILL think you are smarter than me! (Not to mention all the OTHER stuff you have posted.)

ANYway, BangGood’s current description of this meter is copy pasted below:

*Emphasis mine

The description does claim Frequency and Temp, probably because the specs in the table below have entries for the UT210D which DOES have Freq. and Temp. but has a different current range (2A/20A/100A for the 210E and 20A/200A for the 210D).

Once I get mine, I will try to do a mini review and post it to BangGood and bring this to their attention, I think this is a case of human error and NOT anything nefarious. It could be confusing to someone was confusing to me until I looked HARD at the table and pulled the manual.

Thank you for pointing me to an English manual. BG has not responded (yet) to my question about the Chinese manual I got.

I just ordered one. I wonder if it will get out of China before the holiday.

Can we still buy it ? Is groupbuy active ?

I did a brief comparison of my subsequent methods of measuring the tailcurrent of a direct drive 4A flashlight. The subject was a BLF LS D80 (1A, dedomed) with BLF-A6 driver and a Samsung 30Q at 4.06V (so not completely fully charged). I found these currents:

-my Ansman mid-quality DMM with stock leads: 3.01 A

-same Ansman DMM with short thick custom leads: 4.21 A

-voltage over a 0.01 (1%) sense resistor: 46.1 mV

-UNI-T UT210e clamp meter with small device made of 1mm copper sheet: 4.58 A

I made a video of the test, showing how fiddly high current measurements was before the clamp meter, and that the clamp meter with the copper thing was easiest to work with and gave the most consistent result (it will be the device of choice from now on), but that the sense resistor method at least gave the same result, so is accurate as well. The DMM gave too low results even with short thick leads.

Btw, I think my DMM does not work well at the moment, only for a slight moment the correct current displays (I'm sure it gave the normal reading for those moments), most of the time the numbers displayed were all over place while the light out of the flashlight looked fairly constant.

Nice comparison, Djozz.

Next time someone new to the hobby asks why they are only getting 2.7A out of their 3A driver, they can be linked to the video to see what difference the leads alone will make.

Can't wait for my clamp meter to turn up!

Nice djozz. Love the creativity on the adapter for the clamp meter.

Thanks djozz for making the video. Would you be so kind to put in a new thread where we can find it faster for future reference. Many thanks.

I asked a few pages back. How do I get a code, and where do I buy it?

I agree, that part is not very clear. The answer is that you must contact freeme. If you make a post in freeme’s group-buy thread requesting a PM about that deal you’ll get what you need.

I did- post #626 2 days ago. I’ll just PM him then. Thanks!

I have added it to the 'djozz tests' thread which is linked in my sigline

Thanks freeme. Made a purchase yesterday.

Received mine today. Surprise, had batteries installed. not so good surprise: Chinese instructions & Warranty. Fortunately thanks to another poster a PDF is available for download.

Not so good part: thanks to USPS LastClass® Service it took longer to get from New York to Pittsburg than it did to get from Banggood in China to New York.

Thank you Freeme.
