ZOYI ZT102A CHEAP-O Multimeter Review & Teardown!

[@707SonomaComa]

Great video. They're all good actually. Very informative and you talk all about the tool, you don't get all sidetracked and tell stories about some other mumbo jumbo. You keep all the focus on the tool. No cussing, swearing, or bad mouthing & bashing makes your videos a joy to watch. Thanks for the great info!

[@KeepOnTesting]

Many thanks! I try not to get sidetracked , I tend to keep the focus on the multimeter as opposed to me 😀👍

[@radius.indrawan]

great review Darren. hey i just spotted an upgraded model of this meter (i think..), ZOYI ZT-300AB that is. kinda like a ZT102A with a bluetooth comm (and normal LCD instead of inverted LCD). hopefully it's been caught up in your radar for upcoming review. Keep on testing!! 😉

[@KeepOnTesting]

Great update Radius..thanks 😊

[@radius.indrawan]

@@KeepOnTesting does the continuity as fast as DT9205 series meters?

[@KeepOnTesting]

@@radius.indrawan Yes, I can't tell any noticeable difference..excellent continuity!

[@radius.indrawan]

@@KeepOnTesting awesome! i just found a good deal for it in my local online shop, for US $11 only. i guess i'll need a new meter for this new year, right? 😜

[@youtubeZOYIZOTEKinstruments]

great video, thanks Darren~

[@KeepOnTesting]

Thanks for sending those multimeters for review!

[@phaedra9698]

What's the difference between ZOYI & ZOTEK? I couldn't find a zoyi website. zotektools.com/ is basic, with various small errors. There are many other brands of 102 that appear identical (Aneng, Richmeters, Mestek, etc.) [Of course, all taking their name and inspiration from Fluke.] Which are "real" vs "copy" vs "rebranded"? Are there unsafe copies or fakes out there? (I'm in Indonesia, where Zotek appears to be the most popular of the "cheap but not cheapest" multimeters and does have some online sellers claiming to be an official store.)

[@alpsinan]

Your models are sold under the name of Toolfix. Who is the original manufacturer of these models?

[@protarget1]

OEM Multimeter, I have the exact same, in nice red colour, sold as the "Aneng AN113D" :-) The screen is difficult to see when the meter is vertical, around 90 degrees. BTW an angle you never view at. Also to get the probe shroud off is easy. You squeeze the plastic at the very bottom, twist and pull. Hey Presto, off

[@camurgo]

Nice review Darren. It's funny that both you and the channel "learnelectronics" uploaded reviews of this model at the same time. Both videos are side by side on my feed :D

[@KeepOnTesting]

Hi Leonardo...Yes that was quite a coincidence...! Definitely a multimeter that was due for a review. 👍

[@OKBAOK]

Leonardo Camargo I'm about to tell Darren awhile ago when I received same both notification 🙂👍🏻

[@3rdpig]

Nice review, thanks! I don't get the love for the Auto feature personally. I guess it's just me but I end up not trusting it and switching to the correct mode just to make sure. Which means I test everything twice and it takes longer. But at least with this one you have a choice.

[@KeepOnTesting]

Right on Chuck...something to be said for old school! Albeit, this "AUTO" mode actually worked, I probably wouldn't use it myself either!

[@anothervoyager9654]

Happened the same to me.

[@УСереги.Делаемсами]

[@electronone5219]

I have the ZT109 ( ANENG AN8008 ) which is good for basic electronics. I like the review as well as the Zoyi ZT102A; however, they need to put bigger HRC fuses--when those tiny fuse blow, it might allow a high voltage spike to jump across the fuse holders.

[@KeepOnTesting]

Definitely agree! Those tiny fuses are way too small..and easy to arc over. I would rather see a resettable polyfuse on the mA side too.Input Protection is not its strong point a little more thought and it would make a big difference.

[@derektodd4126]

2 reviews of the same meter within 10 minutes of each other. Yes the auto detection starting to get abit quicker. BTW I like your reviews alot more, don't worry Paul.

[@KeepOnTesting]

It was indeed bizarre, I had to take a second look myself! That being said, always room for more...thanks Derek. 😀👍

[@iwayanpujawan7267]

acurate or no for capacitance test?

[@clodvonclout]

13:47 I was hoping that you were able to compare the current draw of 102 vs 102A. I uave a 102 now but hesitant to purchase 102A as i believe the 102A has a permanent on backlight and should drain the battery faster than 102. From your experience how does the LCD backlight affect battery life in general compared to having it off?

[@juleshaaa575]

Baterai tidak boros kawan, Darren sudah membuktikan nya. 2,5 volt dia masih bisa menghidupkan lcd, rata rata arus hanya 10 miliamps

[@pounsfos]

Great review, but no test of current accuracy? Still buying one.

[@unk_48]

Mr darren, what happens to this multimeter if it accidentally enters the voltage when the mode selector is in ohms, diode and capacitance, is there any protection from accidentally like that in this multimeter?

[@16BITMEME]

Please can you tell me Why my true rms meter can only measure voltage less then 1.5Khz 😢 (Brand) Smart Sensor ST833A

[@pr0xZen]

I've been using these little DMMs for hobby and work for 3'ish years, IMO they're pretty damn good value. My only gripe with them for my use, is that they're not super great for _really_ low value accuracy, and the buzzer is a bit too anemic. If in a fairly noisy environment, it can be difficult to hear it. The thermocouple readout is whole numbers only, but honestly that's the accuracy of most common thermocouples too so, eh. And get a K-type to dual-banana plug adapter. Really improves usability with that kind of stuff. The probe plug spacing is "standard" so most such adapters on the market will will work.

[@KeepOnTesting]

Some great points! Thanks for the update. 😀👍 Value wise they are really good !

[@pr0xZen]

@@KeepOnTesting Absolutely. I mean, for the price, these units are worth it even just for having a thermocouple reader with a flip-stand and lit-up display. Bonus feature: your Thermocouple reader is also a fully functional multimeter 😁 Between home, car, garage and work I have like 4 of them.

[@KeepOnTesting]

@@pr0xZen Sounds 👍 you have your bases covered ! Great job ! Now what about that "fifth" multimeter! 😀

[@pr0xZen]

@@KeepOnTesting Still window shopping for the 5th. That one needs to be more premium: Full PWM support, faster polling, louder buzzer, more accuracy down low (ideally, good for shunt resistors down to 5mOhm,bit probably need a dedicated device for that kind of low-value accuracy), and have usb or low-latency bluetooth data connectivity. If you know of one that fits somewhat close to that, don't hold back ;)

[@tefatronix]

You might like the new-ish UT136B+. I have the older (non plus) version and saw the newer "plus" version, not so great specs wise, but surprisingly nice build quality for the price. Looks like Uni-T upped their game quite a bit lately. Anyway, watched quite a lot of your other videos. Good reviews.

[@KeepOnTesting]

Actually there will be a review out next week on that very meter! Definitely UNI-T has upped their game and are putting out some decent multimeters! Thanks for the feedback.

[@romeoj387]

I have zt102A , the lcd display good at dark/indoor room. But i feel annoyed when outdoor or under daylight lamp. Can we hack it to be negative display?

[@KeepOnTesting]

I'm sure there's a hack but no links unfortunately

[@vandroid177]

On startup screen and manual book there is min, max, and manual mode. Do you think this function possible to use?

[@KeepOnTesting]

Unfortunately not . These displays are sometimes utilized in more than one multimeter so even though the symbol appears it has no PCB functionality embedded into the unit...basically, "the lights on but nobody's home" syndrome 😄👍

@@KeepOnTesting What your recommendation clamp meter under $30?

[@yubinator7455]

Would you recommend this for DIY hobbyists and/or engineering students that learn elementary electronics? The ANENG M118A is around $2 cheaper than ZOYI ZT102A (it is ANENG AN113D in my country).

[@KeepOnTesting]

Zoyi ZT102A would be my recommendation. 😊

[@danielristov736]

which one consume more battery zt102 or zt102A ? And which one have better Screen Visibility in direct Sunlight?

I would say they should be equal for the battery drain but the LCD should be better inthe sunlight.

[@halrhoads6194]

Sweet! Especially that AUTO feature. One question: did you remove the boards to see the number of layers? Was it the same? Less? Thanks.

I didn't go quite that far, but from my vantage the new Zoyi appeared to have a slightly thicker pcb.

How can I measure the frequency of my mains? I can measure it from the voltage knob. But when measuring it from the Hz knob, it shows incorrect values. Great review btw. Best I’ve found.

[@KeepOnTesting]

Make sure you're in ACV mode..then simply measure the voltage and use the yellow select button to switch to Frequency and Duty Cycle. It should work. If not..the dmm is defective. BTW. The Frequency functions won't work in AUTO mode you must be in AC volts then use the SEL button to get the Frequency. Many thanks for the kudos!

[@ruangkerajinan6938]

Zoyi 102a/zotek 102a?

[@yambo59]

Not too bad - these displays are always nice, but always shorter battery life as they die quick where an lcd would still be useable. It has a better than usual auto range and shows improvement in this area, but cant see low mv, and a regular auto range where you select yourself seems to still be a bit faster. Nice to see it has a REL button and really good continuity, but when will they ever get rid of those lame mini fuses that no one seems to have, and if they do they want stupid money for em. One could install an auto reset on the mv and solve this easily. I notice this one has no relay like the Aneng version does, im taking that as an improvement - or a cheapo cost cut-lol Overall not bad for the price.

[@KeepOnTesting]

Agreed, those tiny fuses are useless! Would love to see a resettable polyfuse on the mA range. This is the best "auto" implementation thus far in the CHEAP-O genre..fast and furious! Definitely worth the dineros!

[@bmh4013]

Hi bro i have the same multimeter except the name RM 102 pro , i am found my both fuses are blown, my question if FUSE is blown will it affect capacitor measurement coz i cant measure capacitor. thank you

@@KeepOnTesting You don't really want a hard-to-scratch display cover on these cheap units, that mean it'll have to be lime glass or plexi. And while they don't scratch so easily, they _crack_ much more easily. The numbers are big and clear though, this thing can take a lot of beatings before the display area become so scratched it impacts readability.
