Best Clamp on Meter for Benchwork Owon CM2100B

[@qzorn4440]

Wonderful little meter. 🥳 The clamp on meters are great for VFD AC motor drives and large fork truck battery inverters. Bluetooth is nice for remote testing. Great video.🤩 Thank you. Amazon $45 OWON CM2100B Clamp Meter Digital "Bluetooth" Function Meter AC/DC Current and Voltage Test, with VFC Overload Protection Function True-RMS Test 20,000 Counts My wish list is to use the Bluetooth data in a simple oscilloscope smartphone/laptop app with a true signal trace zero . 🤔 Also, Power Factor function is nice for wind turbine projects .

[@KissAnalog]

Thanks for your great feedback! I love the idea of PF in these meters;)

[@aurthorthing7403]

WOW! The non-bluetooth version is less than 35 bucks! It costs less than the UT-210

[@KissAnalog]

Thanks for pointing that out. It is about $10 les for the non bluetooth. Here's the link: amzn.to/3uG7Oz0 Comparing it to the UT-210 is awesome - as they really have the same functions but the UT-210 is 2k count which is very low res - especially compared to a 20k count;)

Bought one at ali for 24,8 euro, still in china sadly. I have several devi es with BT and only real usage it has when i checking temps on some device,electronic stuff for long time under load. Honestly BT is for me much more gimmick

[@aurthorthing7403]

@@grindererrofficial3755 BT comes in handy when checking intermittent parasitic loads on vehicles.

[@davidkclayton]

Nice for the money. Here's my wish list for a clamp on meter. Dual measurements and display for volts and amps and a potential math display for power. And for the app, away to input a resistance value for the load so the power calculations can be displayed based on a volt or current reading only. 🤔

[@KissAnalog]

Thank you! Those things are on my list too;)

12:03 I'm sure we've all had times where we had to chuck away included batteries that came with equipment or put them to work in something else do to being DOA or drained before use. Sometimes I'll chuck them into something like a remote, though I do recognize that the things might leak in those. But, hey! If they're good enough to work, there definitely is no reason to straight up trash the things.

[@KissAnalog]

Thank you! I have never had a chinese battery leak on me - although they may not last as long. I just think we should not crap on Chinese batteries when the instrument itself is made from China - but some reviewers feel some crazy pride and toss them without draining them first. How do they even know how good they are;)

[@versace885]

HI Eddie, great info.. Thanks for sharing. 😅

[@KissAnalog]

Thank you!

[@MrDingaling007]

Just bought one today, can't wait to try it out, we might have a new champion to finally beat the hacked eeprom Uni-T 210E clamp meter.

[@KissAnalog]

LOL - We will be happy to hear your thoughts on it once you get it;)

[@Gelf54]

I like the 2A range (for measuring parasitic battery draws) but am still waiting for one with Peak Hold (Max/Min) as well. Can't hurt to dream.

[@KissAnalog]

Yes you are right;)

[@johnshaw359]

Preferred this to my uni-t 210e that went bat-sh*t-crazy on me a few months ago.

[@KissAnalog]

Thanks ;)

[@davidkclayton]

I have a Extech mini ACDC clamp-on meter, that just loves coin batteries😐

[@KissAnalog]

Yes those coin batteries don’t last too long;)

[@ssalient]

I have got this meter (the bluetooth version) and it's a nice meter to compete with the well known UT-210E, however with some things to bear in mind. 1) in Current range it is not 20.000 counts but just 2000, like the UT-210E. 2) Auto-ranging is exceptionally slow on this meter. Edit: Mine actually defaults to DC in Voltage and Current modes!

[@m1k4c]

you mean blluetooth?

[@KissAnalog]

Thanks for your feedback! I wonder if my model is already been updated or yours has been? :)

[@ssalient]

@@KissAnalog Logically one would think default modes are consistent so either everything defaults to AC or DC.

[@KissAnalog]

That was my thought. It would make it easier to remember :)

[@EuphoricDan]

What are the measurement edges for these things? Were I to have a sq 10kamp wave on a 1% duty cycle could it measure that as 100 amps RMS?

[@KissAnalog]

Thanks for asking. OK - I have to ask you where do you find a 10k Amp square wave with 1% DC? ;) Just asking because if you really know a case - I'd like to hear about it.

[@EuphoricDan]

​@@KissAnaloglul, ya I guess that is pretty extreme. I'm trying to make the biggest pulsed magnetic field possible (shooting for 5T atm) for funzies by using a few loops of heavy machined electrical copper as a custom made coil. It's relatively low voltage (12v) and the h bridge will have a bunch of high current parallel fets. If I need to cool the coil or even supercool it I will. I'll probably have it dunked in liquid nitrogen before I turn the power on full for the first time tbh. Right now I'm just trying to figure out what kinda decoupling(this is the name?) capacitor ill need to catch the flyback from the field collapse. That's a good way to explode my batteries if I mess that up I think. Edit: I already had a coil explode on me last year before I understood flyback. I had a kw through 500 loops and it rapidly started getting too hot so I airgapped the circuit to turn it off. Field collapsed and the coil physically exploded, or at least very rapidly and chaotically came unwound with smoke and fire. It's amusing to look back on but it was less fun when I was trying to deal with a heavy flaming mess of unwounded copper wires in my bedroom lolol.. No more mistakes like that. Anyway my Tesla meter isn't fast enough to give good readings so I'm thinking of just measuring current through the coil

[@pault6533]

Beeps too much. The developers should make quiet beeps except for continuity and diode. Gives the UT210e a run for its money. I like to see the low and high range of measurements and speed and stability . How well it meets calibration doesn’t need to be the main focus, maybe just a mention what you found. Keep doing a good job and being unique. You don’t have to be like anyone else!

[@KissAnalog]

Thanks for your great feedback! I appreciate you!

[@terencekaye9948]

So, why would you need blutooth? No fuse? Pretty neet though hopefully not too expensive. Can't see it lasting too long.

[@KissAnalog]

Great questions! Bluetooth can be very helpful when setting up a measurement - and then going into a panel and turning the power on while watching the measurement on your phone. You do not need a fuse because you’re not putting Current through the meter. The clamp on makes it safer. It feels very sturdy and looks well-built - so why don’t you see it lasting long?

[@billisnice]

I fear the durability of the meter. Will it hold up dropping and slapping around?

[@KissAnalog]

It does feel very durable. Funny thing is - I think a lot of people think a certain meter is higher quality and durable - but really very few meters from some expensive brands are drop tested. It is a fallacy that people think they are. Also, if you do drop this meter in a way that would break it - you can buy a new one without crying about the expensive one you could have broken with the same fall;)

Hola, yo compré esa pinza por ALIEXPRESS hace unos meses desde chile.... todo funcionaba perfecto , menos la funcion V.FC , cuando media corriente y la activaba , se caia demaciado la corriente, estaba mal esa función.... entonces me puse en contacto con OWON, les mande videos de la falla y constancia de la compra de ALIEXPRESS , y despues de varios correos me enviaron otra pinza por garantía, y ya vino sin falla en la función V.F.C .....por lo demas es excelente pinza, muy precisa en corrientes bajas. La recomiendo..... Solo le coloque un VARISTOR de protección en la entrada, ya que no trae... le puse el 07D561K

[@KissAnalog]

Thank you for this fantastic feedback! Please let us know if you would recommen this meter with your experience.

[@miguelc_seeker]

@@KissAnalog Hola.... por supuesto que recomiendo esta pequeña pinza. La he usado en tableros industriales y vivienda, aún está calibrada y confiable, es muy agradable poder medir en espacios pequeños por qué entra con facilidad. Yo recomiendo siempre tener una pinza de mandíbula grande y una pequeña. 👍🇻🇪🇨🇱

[@The_Ballo]

Any way to make it default to DC amps?

[@KissAnalog]

No, but it would be great if they made that option with every meter;)

[@wahng9552]

Does it turn off after a certain time of idle and if so can you also disable that function ?

[@KissAnalog]

Great question, yes, I tried to show that the video, but I may have not been very clear.

[@ayhan8928]

❤❤❤

[@KissAnalog]

Thank you!

[@snabelsvin1]

You forgot to mention the accuracy of the other resistance ranges. don't make people think it's .5% on all. It's 5%+10 digits on on the 200 Meg range. The bluetooth is a gimmick. Totally worthless. It's more expensive than the Uni-t UT210e which also has a 2A range. OWON has zero support. This is not the best clamp meter.

[@KissAnalog]

Thanks for offering that data. I think Bluetooth is awesome! You can set up the meter - go to a panel and switch it on - and see the measurement. This is just one example. The Uni-T is only 2k counts and this is 20k counts. Owon is quick at getting back to me. What kind of support do you need? It’s just a multimeter.

[@snabelsvin1]

@@KissAnalog Yes, bluetooth is awesome, but the way OWON implements theirs is not since you need the app to make it work. I have a B41T+ from OWON where the COM jack broke in the plastic part of the case. It was so tight you barely could get the leads in there. Banggood did after some complaining provide me with a new front half of the case though. Then the range switch died a month after that. I bought a brymen in stead. I needed firmware for my HDS2102 since the website did not work, I e-mailed them and they never got back to me. But you did, thanks Eddie.
