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

interested if less than $30 us
thanks for your efforts

interested

Interested depending on price.

Any news on the GB, folks??

Well, I’m wondering myself

Yes it would be nice to now. There are over 70 people signed up, so the problem definitely isn’t lack of interest on the part of buyers. However I don’t have a lot of patience. If the GB doesn’t happen within the next week, I’ll probably just buy one elsewhere. They can be bought for about $36 from US based Sellers on eBay. The box I see is that if the GB doesn’t happen in the next week or so, we are looking at a roughly 4 week delay because of Chinese New Year, so delivery ends up Late February-Early March. Don’t know about others, but generally I buy things because I need them, and I tend to need them sooner rather than later. It doesn’t seem to me that 6-8 week delivery time frame is worth the $5-$8 we may save on the GB.

Got a UT210E today from Tomtop - wow, excellent! I thought my DMM setup was pretty tweaked, but did a couple of quick comparisons, measuring at the tail. I got 14 AWG leads on my DMM, and used a short 16 AWG wire looped thru the clamp meter wit wire from the cell minus to the battery tube edge:

  • new Nitefighter F30B stock: 2.31A on the DMM, 2.41A on the UT210E

  • fully modded Convoy L2 (dedomed U4 1C, FET+1 driver): 5.09A on the DMM, 5.43A on the UT210E

This is sort of what I might expect - low amps close, high amps the clamp meter shows higher. Still I was thinking in the 3A and below range, my DM tail readings were pretty good, matching well with the # of 7135's I'm using in the drivers.

UT210E readings are with ZERO'ing before taking readings, and using the 20A scale.

For the group buy, freeme has been OD'ed on GB's, so he's catch'n up now - should happen real soon (hoping...), along with the BOSS1. I think GB's out of the norm are probably more involved, norm being stock Olight, SWM, NiteCore, etc...

Thanks for the update Tom E. Does your clamp meter hold a steady reading or does it waver slightly?

I will PM to all in awhile.

That’s exciting… Should I wait up? :wink:

Very nice, if soon can start ordering

Tom, do you have any Triple’s you could measure? On that theme of more is more, it’d be interesting to see what would happen at the top end of your DMM.
I have single cell lights pulling 17-21Amps. One is even a single emitter light! This alone is worth getting the clamp meter for, as the DMM would surely fry up there.

Ah hell. Add me to the list also.

Firts unit ordered, great and many thanks to freeme !!
Second as well.

Received PM. Thanks freeme! I will order asap!!

UT210E ordered. Thank you!

UT210E ordered. Thank you freeme!
Hope it gets shipped before Chinese Newyear. Waiting to compare the readings of this one to those of my old DMM.

I have this meter for more than a year and half and I really don't know how to zero it :)

I also got much higher readings than with dmm for high current draw lights.

Also I would suggest very hard press to both surfaces (battery - and exposed aluminum on flashlight, or you could get lower readings).

What happens if you turn the cable the other way around in the clamp?
I got a UNI-T UT203 that I useally use for higher amp readings and when I messure it with the cables the other way I got higher readings.

PM the info please.
