TA-0416: Owon CM2100 CM210E - UNI-T UT210E - BSIDE ACM91 - Test Teardown

[@Stephen_Heathcote]

Really good review there Tony. Good to see all under test from the same source at the same time. Nice also to see dc clamp meters are getting more available at decent prices 👍

[@TonyAlbus]

Thank you Stephen!! was in my list to see at least the CM2100 and UT210E together, then i went a bit overboard with 4 :) still was possible on the desk. I am also surpriced, the price dropped on the DC clamps and they are prity sensitive and working properly.

[@cesardavmun]

Good review, thanks

[@TonyAlbus]

Thanks!

[@mostlypostie1]

I have the UT210e, modified for 6000 counts, and default to DC, and longer backlight. And some other functions too. Its fantastic! The latest UT210e versions will support 10000 counts. 73

[@TonyAlbus]

Thanks, yes the hack it great, but not easy for everyone. so i tested it factory

[@EfieldHfield_377]

Great review as always Tony. Uini-T continues to impress.

[@TonyAlbus]

Thanks! yes they are getting better and better arent they?

[@alpcns]

Always enjoy your reviews and tests, very well done. Thanks Tony!

[@TonyAlbus]

Thank you so much!

[@M5AXA]

Wow Tony, Such an in-depth and comprehensive video you have produce here. You lab just grows and grows and does your ability to produce interesting and high quality video's. Regards Ian

[@TonyAlbus]

Thanks Ian, yes this was so much fun to do.. and i wanted to try the fancy cables and show it mostly all at the same time. was big fun .

Voltcrafr VC330 is same meter , has the 210E printed on the circuitboard , saw another teardown on Diodegonewild YT channel

[@TonyAlbus]

Thanks!

[@graeme0]

Fantastic review and really helped me choose. I had the Uni in the basket before this but changed to the Bside. Thanks

[@TonyAlbus]

Thank you, great the video was of use for you.

Very helpful. Thank you

Thank you!

[@svetlinbarzev9110]

Thank you! Exactly the review I needed, as I was wondering which one exactly from these models is best for low current DC, I think I'll go for the Uni-T :)

[@TonyAlbus]

thanks you, good to know it was a good help.

[@jwong19]

Hi, thank you for your detailed presentation. Looking the way you try to read the IC's stamped information, let me suggest the use of a lens polarizer on your microscope lens that will facilitate the reading and best PCB observations...my respects from PR.

[@TonyAlbus]

Thanks! , Great suggestion!

[@jwong19]

@@TonyAlbus A pleasure. Thought it helps.

[@TorchHacker]

Thanks for the comparison! I've been using a 210E for a while and find it annoying to have to change the current range, select DC, zero etc when measuring the current of flashlights.

[@TonyAlbus]

Thanks, yes agree that autoranging would be so much better

[@TorchHacker]

@@TonyAlbus I went ahead and ordered the BSIDE ACM91. Zoyi/Zotek don't appear to make this one but some of their newer clamp meters (QS9) have been rebadged as BSIDE.

[@TonyAlbus]

@@TorchHacker Yeah, you will like it!

[@opablo_gm]

great comparison... I lost my UNI-T UT210E and just ordered an Owon CM2100 just so I can get to know that brand (because UNI-T is well known to me and with random great devices like the UT61E which I also happily own)... for future clamp reviews it would be great if you also put in camera a trusty dmm (fluke/keysight/gossen) also measuring the ac/dc current but in a wired way through it's own internal shunt to have as a reference more accurate measurement on screen

[@TonyAlbus]

Thanks, nice!! on the DC 100mA i had the GDM9061 6.5 digits i would say good enough :)

[@BjornV78]

3:39 Weird, last week i bought the Uni-T UT210E from Eleshop, and it came without the crocodile clips. Also these crocodile clips are not mentioned in the content list on my manual.

[@TonyAlbus]

Hi Bjorn, i got these from Amazon a delux version.. i had vouchers. usualy i would indeed get it from Eleshop.

[@BjornV78]

@@TonyAlbus , ahaa, that explains a lot 🙂

[@guateque1718]

Thank you.

Thank you for watching!

[@tonogtube]

My favorite clamp for small currents is UNI-T UT210E.

[@TonyAlbus]

Thanks, yes was very good in low currents

[@pault6533]

NCV = non contact, Live = use positive lead. The NCV is read at the little triangle on the tip of the clamp. I like the BSIDE but the plastic looks cheap. I see they sell a blue version that looks a little better.

[@TonyAlbus]

Thanks Paul, you are perfectly rightm i know that LIVE from Kaiweets, but somehow did not connect the dots in this device.

[@pault6533]

@@TonyAlbus Thanks for always coming back to answer our posts. I enjoy you positive spirit and the unique perspective of your reviews!

[@TonyAlbus]

@@pault6533 Thank Paul, comments like this make my day!

[@TYGAMatt]

I love my UT210E. It's a fantastic little tool. The only annoying thing is that as you mentioned, it starts in AC. I do mostly DC work so it's a bit of a pain. I have seen a hack that helps stabilise the current sensing and also changes the voltage and current defaults to DC but I dare not attempt the hack as I know that I'll brick it for sure 😂

[@TonyAlbus]

Thanks, yes i am not risking it either.. i will break it too :)

[@mostlypostie1]

​@@TonyAlbusit's a very easy and safe hack. You should do a video on it! I LOVE my modified UT210e!

[@TonyAlbus]

@@mostlypostie1 thanks

[@markusreinhold8836]

Thanks a lot for your comparison! One question: How is the behaviour if the clamp meter will be moved (orientation,...). Is the offset jumping especially in the lowest current range? Is there a big differences between the 4 current clampmeters? Background: The usage of clamp meters by hand and not still on the table, the orientation of the devices is not perfectly constant. If the offset is not stable it could be hard to measure low current.

[@TonyAlbus]

Hi, i think you need to 'zero' it in the orientation you are going to use it. aspecialy when using in hand.

[@set3777]

Table at 42:43 CAT rating of BSIDE ACM91 is NOT "blank" but certified at CATIII 300V, CATII 600V.

[@TonyAlbus]

Thanks

[@ssalient]

I've got both the Uni-T UT210E (hacked to 6000 counts) and the Owon 2100B (Bluetooth version). Funny how my Owon defaults to DC amps in all ranges, and these all seem to default to AC, but the Volts defaults to DC, weird choice to make this different I think. Also, the Owon may be 20.000 counts, but in current measurement mode (which is what people will buy this mostly for) is only 2000 counts. I think that's kind of misleading advertising, but the price (about 20 euros/dollars lower than the Uni-T) does make up for that. In my case, I like the Owon better because it is more accurate and stable compared to my Uni-T. I have an earlier version of the Uni-T I think because my PCB doesn't have the massive row of little caps soldered on it. Maybe I should just get another one some day.

[@TonyAlbus]

Thank Marnix for you feedback on both of them. nice to hear from a user who has used both of them for a while

[@sbelectronicaindustrial6652]

👍👍👍👌👌👌....!!

[@TonyAlbus]

Thank you!

[@MickDownUnder]

Owon are building some nice kit for the hobbyist. Others like Uni-T are hit and miss like with the UT210E and UT181A which are awesome meters for the price but they build some cheap junk that poisons the well for them.

[@TonyAlbus]

Yes those hit and miss are a pity they do have nice stuff. Sometimes Brands just try stuff.. Siglent made a PSU that was a waste of money, but the scopes are good. every brand has something that they are not good at and try it anyway

[@interview-yj9jk]

Hello.. Can you compare winapex 268b vs ut210e Thank...

[@TonyAlbus]

When i have one i will, i don't have it at the moment.

[@ThePupil]

Have you ever tested Owon CMS101?

[@TonyAlbus]

Hi, no i have not. maybe Owon will send me one once

[@林林-i4u1n]

I suspect that owon is the OEM of unit

[@TonyAlbus]

and to make it more complicated, i will have the NIBOO UT210E soon on video too

[@miguelc_seeker]

Hola, tengo la owon y la Unit.... y prefiero la Owon.... En mi caso la Owon es más precisa a bajas corrientes que la Unit. Le realice igualmente pruebas a las dos, y para mí la owon es mas completa, Aparte que no se tomó en cuenta su APP en esta revisión. 👍🇻🇪🇨🇱

[@TonyAlbus]

Thank you! .. i have heard from other viewers too, they have both the uNI-T and OWON and like the Owon better too. these did not have bluetooth, i do have a video about the CM2100B version.. there i show the APP if you are interested.

[@LawpickingLocksmith]

Today is not Friday and none of them is a Fluke.

[@TonyAlbus]

LOL :) yeah !!

[@LawpickingLocksmith]

@@TonyAlbus Proves the point that every meter has its place. Measuring is a task of comparing the unknown to the known. Instead of being concerned about brand name it is more accurate to take many measurements with a spread of meters. Say if taken a reading on 3 and one is off then add a meter and find out why. Some say true rms but give them a combined ac with dc offset and the good old analog meter is likely the true rms winner.

[@TonyAlbus]

@@LawpickingLocksmith Thanks.. good point indeed... thought it would be nice to have 4 at the same time..
