Also note, if you don’t now what it is.. That the 210e has 2000 counts
This means that a value of 1.999 will be displayed as 1.999
A value of 2.001 will be displayed as 2.00

Just FYI

Also note that, technically, resolution doesn’t mean accuracy… This means that something (hypothetically) could be more spot on (regarding accuracy) than something that has more displayed digits (resolution)

But generally resolution comes handy when you have to see small changes

After reading this thread I remembered that I’ve thought about buying a clamp meter before. The 210E seems to be a good choice so I’ve bought one from the Tomtop store (Tomtop.com with warehouse in Germany). Currently on offer, the price seemed to be ok and delivery should be faster compared to other China stores.
The accuracy for DC current is listed with 2%, not bad compared to other models in this price range. I would have spent some more for the MASTECH MS2115B (on offer in a German store for 55 Euros, but it has only a 40A range and higher. Although 6000 counts and an USB port… The PC interface could be used to do measurements of charge/discharge currents over time.

Done.

I’m interested to see what price freeme can get, because there are some good deals on it on the wb already.

In the Ali 11/11 sale for $38.It has auto DC ranging and a temp probe above the E model. most people won’t need those features if the E is significantly cheaper.If you can get it for under $30,I would recommend it.

i had once a cheap mastech clamp meter but it was a lot more inaccurate than the cheap 20$ DMMs I have. I had to wind the measuring cable a few times around the clamp and calculate the average.

The cheap DMMs have the advantage that they use these simple glass fuses which only cost cents but won’t work really good as a protection because they can let through a high power pulse. The better DMMs have the big fluke fuses(like in the pictures above) and protection circuits build in. So you can tell from the fuse used if it is a good or a bad quality DMM. There are a few very nice videos from eev blog on YouTube with lots of infos about DMMs. But these fluke fuses cost 10$ each…that’s why I like cheap DMMs and normally the cheap 10A fuse is made to work with 10A easyly which is enough for most flashlight needs and with triple direct drive builds I try to measure not longer than needed. But thes don’t break so easyly(minutes). Datasheet http://cdn-reichelt.de/documents/datenblatt/C400/TraeGE%23ESK.pdf 2minutes at 20A…

I also ordered one of the modules from eBay but didn’t tried it yet.

You guys might want to take a look at one of those cheap RC watt meters if cost is a concern and current measurement is the only thing that interests you. I got mine off Ebay for $14 and it seems reasonably accurate.

But the question would be what voltage drop will be caused by the meter… The measurement will be accurate but the current could be much higher if the drop is too large to be negligible.

Will try to get a quote on Monday. DMM is not in flashlight department, so it may take another few days more to get an answer.

TheBo do you agree the 210e would be good for our purposes? It has the 2amp range that some others don't have. It gets 4.9 out of 5 on Amazon with 26 reviews, and it's nice and compact. Freeme: you think we can do a fast turnaround time on this one?

UNI-T DMM's have been rock solid for me - I got two, never a problem. A "super tech" I work with has like 5 of them all over his lab, plus others he has at home. He's got a Fluke also, but loves his UNI-T's.

I'm in on a UT210e deal for sure. The UT204A is $41 at FastTech here.

Dale has a MasTech, not sure of the model...

The big fuses are only necessary when working with higher voltage and high current, like in industrial settings.

The small fuses can break anything at low voltages, but the meter may not have enough protection to handle the current.

Clamp meters are not precision meters, but are fine when a few percent tolerance is acceptable. They are not good at lower currents, there the precision will be even worse and it is important to zero the meter

I’m in on a UT2010e at the mentioned price range, but I prefer an option for direct pay, not through PayPal if that’s possible. Interested regardless, awaiting details.

(Edited my post and noting that PayPal is pretty universal and I’m quite sure will be usable here if you want it- I just prefer otherwise where I can)

Useful meter with decent reviews.
I will support a group buy for the 210E as well.

I’m also interested in the UT210e, but it will have to wait until the 27th for me to get it – Christmas left me broke;-)

If you have to wait that long, you might have to wait much much longer. Chinese New Year is coming soon. :_(

Thanks for making me want a device that I never missed before Cry

The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.”   (Gus Speth)

Ahah… It happened the same to me….

Mmm to be honest it happens constantly… And I’m sure I’m not alone in this boat…

I am interested in the Uni-T clamp meter, what do I need to do to join the group buy?

I bought my Mastech MS2108A trying to upgrade from the Velleman DMM I had that I knew was lousy with stock leads but seemed pretty close with home made 8.5” 12Ga Turnigy leads. But I was getting into higher amperage lights and knew too that the Velleman was gonna blow. I’ve read over 21A on the Mastech, thinking I might have seen 36 once but am not sure, that was on a big triple XHP-70 light if I recall correctly but chances are my memory is jerking me around again.

At any rate, I’d like to get one of these to stay on the same page with y’all, have a comparison with the the Mastech and see if we can find “the truth”. Smile

I just ran a test on the Lucky Sun D80 BLF Special Edition, stock group buy light that I received around 10 PM on the 28th of Dec.
With a Sony VTC5 at a rested 4.20-4.21V I got these readings…

6” 20Ga loop from the negative pad, flashlight fully assembled (sans reflector and lens)…. 3.92A
6” 20Ga leads soldered to each pad of the Noctigon, directly connected to the cell… 4.99A
20.5” 12Ga loop tail reading, still same C5 cell… 4.36A
Velleman DMM with 8.5” leads, same cell… 4.04A

So I’m willing to buy this Uni-T model for verification of what I’m actually using now, and comparison to what y’all get using this clamp meter. Should prove interesting…

Dale, Freeme may see your interest here, or you can post “I’m in for the UNI-T” in his groupbuy thread linked in the OP.
