UNI-T UT890D+ CHEAP-O Multimeter Review & Teardown!

[@Brian-uq6jm]

If I understand correctly, 2.512VDC is within the DC accuracy specification so you can't fault it. :D

Hi mates, from Indonesia... wish u good and healthy days. I have been mosty at home during this pandemic. I already designed and installed a mass automatic desinfectant sprayer on an enter road gate (funded by local gov). Now i am an designing automatic hand sanitizer (up to 3 wastafels each) also funded by local gov. It will be installed on local markets, mosques etc as needed. These cheapo multimeters help me much during the devplmt of my moduls (uni t ut136b+, winapex et8102, dt3266l. For working onsite i mostly use little an8203 n clampmtr dt3266l). Thank You mates..

[@KeepOnTesting]

Greetings friend! Excellent to hear that these CHEAP-O multimeters can serve and operate just as well as their expensive counterparts. The fact they are being used to help combat COVID-19 is fantastic and I wish you all the success possible! Stay Safe and Keep On Testing!! 😁👍💫💫💫💫💫💫💫💫

[@TheRadiogeek]

Keep calm and keep your multimeter on. I love it! 👍 nice review as always!

[@KeepOnTesting]

Thanks ! Between the radios and multimeters we will have the ultimate zen experience! 💫💫💫

My Fluke 17B+ actually uses that same nylon-ish type of range switch spring mechanism, has a different feel than the traditional ball and spring style but it works very well -- much easier to re-assemble too--lol

[@KeepOnTesting]

Oh yea! I was on my knees last night under the bench looking for one of those venerable microscopic springs that decided to jettison its way across the bench during a repair..Absolutely love the new nylon style rocker replacement at least as far as repairs go..🤣🤣🤣

[@wibisono2156]

@@KeepOnTesting hello sir daren, which one do you think is the uni-t 136b+ or aneng q10? or maybe there are other options recommendations for me. thank you, have a nice day

[@OLDSCHOOLNEVERDIES]

Solid 4 stars? I bought one UT890D+ on Amazon: instead of measuring 5Vdc like the other three meters I have (Fluke 8840A, Lafayette M9803R and an old Metex portable), it measured 4.464 Vdc. Not only that, on a 200mA current measurement (with the multimeters mentioned above), the UNI-T displayed 220mA. I sent the tester back to Amazon and got an identical one, believing that the first one was defective. The second one also had strong measurement errors in V and A; not only that, it had errors with the capacitance meter. On several 10uF expensive polypropylene capacitors with 2% tolerance, the reading was 12uF, 13uF, 15uF. Unacceptable, so I sent back to Amazon this one too. Believe it or not, measuring the voltage of 5 Vdc with the ultra cheap DT-830B, the displayed value was 4.9 Vdc, very close to the other multimeters I have.

[@KeepOnTesting]

That's not good. Hoping UNI-T Q/A hasn't deteriorated since I initially did this review 5 years ago.😮 Those 830xx clones are solid. Never had a bad one yet.

[@yambo59]

Overall you get a heck of a lot of quality, functionality and value for the low price of $21 US shipped I paid, big brother to my UT39C. As you said how many meters even expensive ones have that audible diode beep, definitely a premiere feature.

[@KeepOnTesting]

It's a keeper!! On my bench now, permanently!!

[@AlexStoyanov-u7o]

Hello. I looked at several reviews of this model, and everyone who disassembled the ut890d+ has a full-fledged microcircuit and not a drop like in this model that you disassembled. I wonder why they did this?

[@MD-yg8rf]

Excellent review. No shielding, non-gold plated switch contact and lower rating fuses are bit disappointing. But good value for money.

[@KeepOnTesting]

Spot on..it does have its shortcomings but all around it's quite a good package!

[@halrhoads6194]

Here's a thought: glue HD foil onto card stock and form it to the back of your meter, if it doesn't already have shielding. What you think, Darren?

[@KeepOnTesting]

Yes, that would work, at least it would be better than no shielding at all. My biggest gripe is why the mfr leaves it up to the end user to resolve. When it's such a simple and cost effective fix.😀👍

[@halrhoads6194]

@@KeepOnTesting Yes. Couldn't cost more than a couple pennies.

[@KeepOnTesting]

@@halrhoads6194 So true!

[@yambo59]

You can also buy nice self adhesive foil shielding, they use it in some meters and especially electric guitars all the time to stop feed back etc. - very cheap as well, but im told if you add shielding you need to ground it to the PCB's ground trace somehow, not sure why think it said something about it becoming a faraday cage if not grounded-?? I could be wrong here.

[@KeepOnTesting]

@@yambo59 a Faraday cage is used to prevent external electromagnetic interference (or noise) from interfering with its enclosed space ..kind of like electrostatic repulsion. Purpose of shielding is to conduct to ground any interference that's encountered so its important ...otherwise you just have a passive emf shield without an actual filter which isn't as effective (but still better than nothing.) As Hal pointed out, it only costs pennies so its unfortunate that OEMs continue to negate such a basic but important part of the puzzle.

[@Kostaaa8]

Very Nice videos, thank you! 19:17 Just keep in mind SPL usually is measured at 1m distance ;)

[@KeepOnTesting]

Great 👍 info..!

[@CliveChamberlain946]

On that large fuse - this can pass 16 amps all day and not blow. Most fuses will trip at 50% over (24a) in about 20 seconds. I think Uni-T has it right, because at full 20A it would harm the shunt and/or soldering past one minute.

[@KeepOnTesting]

Great point Cliff ! 👉

[@mashun-o4d]

Diode beep is really handy.

[@reyleon61]

It was necessary to see the frequency meter as far as it was effective and it gave you 5 stars

[@derektodd4126]

Like that max / min feature on a cheaper meter, have it on my 87V and can be very useful.

[@KeepOnTesting]

Agreed, This meter is definately staying on my bench ! Lots of versatility and don't even get me started on the audible diode function. Awesome value.

[@Kwankwoliang]

What is your opinion about Mastfuyi multimeter. I was thinking of buying either Mastfuyi FY76 (about 15.5 US Dollar in Indonesia) or Uni-t 890D+ (about US 12.7 dollar in Indonesia). it seems Uni-t 890D+ is a better quality multimeter. I am just afraid that Mastfuyi won't last long. I prefer Mastfuyi FY76 because it's auto-range and have VFC function. I just bought a small extrusion machine that is using VFD. I am not quite sure also if that function is important. I usually use multimeter to check capacitor of a machine and to use resistant meter to check whether the Heating catridges and thermocouple are still in a good condition. Sometimes I use continuity test to troubleshoot loose connection and to check fuse. I am not an electrician. I learn things from Internet. What's your opinion? Thanks.

[@diogocarneiro480]

Hi Darren. UT890C, UT890 PRO or UT890D+? Do you think I should spend a little more and buy UT89XD? I will use for notebooks, phone boards repairs and home hobbies. Best regards

[@KeepOnTesting]

I personally would opt for the 89XD...a lot more multimeter for just a little more.

[@diogocarneiro480]

@@heksogen4788 I love the UNI-T quality as of late..😃👍

[@yambo59]

I keep sayin ya almost always gotta clean those lead tips to get good contact, my continuity works great, especially with the probemasters. The live and ncv on mine works surprisingly well good sensitivity, though on those thick commercial cords few NCV's work too well. I like those coil springs on the battery contacts, nice. The nylon arm detent design is how Flukes done it for years, with good material should last for a long time.

[@KeepOnTesting]

I hear ya..I just run them stock for the purpose of testing. Truly a gorgeous multimeter..UNI-T has done it yet again! Dang, I dont even have shares in the company!!💫💫💫💫💫

[@yambo59]

I hear ya, gotta test 'em as they come for the viewers, they need to see exactly what theyre getting good or bad, but this one is 98% great.

[@Baerchenization]

Is the UT61E end-of-life or why is this one so much cheaper? Thanks!

[@KeepOnTesting]

UT61E+ is an amazing multimeter! Check out my review..

[@josecarlosgadea5696]

I was about to buy one of the super-cheap typical rectangular ones, the ones that dont even have a buzzer, for 15€ at my local hardware store, went to Ali to see if there was something better and saw this for basically the same price (18€ shipped), LOL.

[@KeepOnTesting]

Great 👍The UT890D+ should serve you well!

[@scribblemethis]

Have you seen the super cheap aimometer f0601005's on ebay? They're little green and black things, less than $10 including shipping, and seem disturbingly well featured for the price. I've gotten several and keep feeling like I'm missing something. They work well and, aside from a little flux residue, seem fine on the inside? Even have what looks like HRC fuses and at least one PTC. I feel like I'm out of my depth trying to figure these out.

[@KeepOnTesting]

That's identical to the TACKLIFE DM02A which I reviewed awhile back, unfortunately I was not so smitten with the multimeter and it didn't fare well in my review. Keep On Testing!

[@scribblemethis]

@@KeepOnTesting Thank you for the reply. I watched that video, and they really are very similar. I took this one back apart, and aside from oddities I still can't place (I have no idea what a bdx 49a chip is?) I think this is related to both meters in that video. Maybe an earlier version? That would make sense to me. The lower price might just be them trying to clear out old new stock inventory, even if they're selling at a loss. Thank you for helping me figure it out :)

@@crisselectronicprojects8408Thanks, yes I'm aware of the differences. I prefer the UT195E, although not a dual display it boasts a larger clean distinct font. The dual display of the DS is nice but its limited in its scope. Feature and build wise they are very similar but for about 50US$ less I believe the UT195E is a better value. They both have excellent input Protection and are built exceedingly well.

[@KeepOnTesting]

Great question..no need to spend lots of $$$ You need a True RMS Multimeter that has good mV performance. Also, testing the current on the plate of a tube requires good mA performance.. a multimeter that can do all of the above.. no ..not a Fluke or Keysight...get the HABOTEST (KAIWEETS) HT118A 😀👍

[@ocobotec]

Uni-t UT890C+ good equipment but it has a big fault, the letters on the scale are erased, the ink is very bad, if you run your finger over the numbers they will release white ink, and if you keep passing they will end up erasing (it happened to me). I had to print the scale on sticky paper in order to regain functionality. I will not buy that brand again, I do not know how the ink of the higher category will be, I hope it is not like that.
