Hey Darren! Seriously, your video production value has gone through the roof man... Wow! Keep it up. Big Thumbs Up brother! Thank you for the awesome review. Fred

[@KeepOnTesting]

Thx Fred! I've invested some dinero on the backend , glad it's making a difference 😊👍

[@shaunmorrissey7313]

currently around £26 delivered on banggood, that represents excellent value. 👍👍

[@KeepOnTesting]

Great price Shaun! Cheaper still with the Exclusive Banggood coupon code I believe 😊👍

[@TRONMAGNUM2099]

I like it. You can tell they wanted to do something different, and for the most part they got it right. Had it been able to export data, it could have scored even higher.

[@KeepOnTesting]

Yes! Throw in a BT chip with data exporting and lookout! Might seriously impact that awesome battery life though..

[@25hztolife14]

A long lasting battery is always a plus for me.

[@KeepOnTesting]

💯 especially if it's a rechargeable!

[@asteceletronica1872]

Hi Darren Fantastic review, greetings from Brazil

[@KeepOnTesting]

Thx so much 😊👍 Greetings to all my Brazilian friends 🇧🇷

[@strayblackcatsmeow]

Just bought one. Wish the NCV was as sensitive as your meter. Most of the time it barely detects All the other features work great. Well worth the money.

[@KeepOnTesting]

Thx for the update. Too bad about that ncv but glad everything else checks out 👍

[@numerical_error]

Not bad. Looks clean, modern and quite capable. I really hope LiPO and Li-ion batteries become standard in multimeters. Some of my tools still use 9v Krona batteries. Not only are they expensive, but they're like 200 mAh for Ni-Mh.

[@KeepOnTesting]

Definitely a 2024 looking dmm for sure! Those rechargeable LiPO cells are not only long lasting but cheap to replace. Quite a progressive multimeter at a very reasonable price. 👍

[@ikansalto4612]

Hey Darren, can you do a review for Aneng 622. Quite interested in this multimeter.

[@KeepOnTesting]

@ikansalto4612 Sure thing..just added to the list ! 👍

[@Nazmi_PWM.C]

It has a resolution of 1 milliohm. A very rare feature. nice job FNIRSI.

[@KeepOnTesting]

FNIRSI blindsided the CHEAP-O Multimeter Realm I 2024. This is going to be a great year for test gear! 🙌 Resistance 9.999MΩ/999.9KΩ/99.99KΩ/9.999KΩ/999.9Ω/99.99MΩ It doesn't do millohms unfortunately 😅 no 4W here...

[@TheTrooper115SFS]

Hey Darren, what should I be looking for in a DMM for electronics and ham radio type work, specs and features? So much out there, I'm just starting out and don't want to get something I'll just replace right away. Thanks for all the videos you make, I love the tear downs.

[@KeepOnTesting]

Hey my friend...Thx for the kudos! Bench electronics/ham radio reccommend.....well a multimeter with good resolution and precision is important. I'm currently the midst of updating our TopTen CHEAP-O Multimeter list [should be completed by end of March] I will say the DMT-99 is a multimeter I could easily reccommend and it has a very user friendly interface with really good precision. Also the KAIWEETS HT118E is another greeat all around dmm.

[@cesarhoyos6955]

good review

[@KeepOnTesting]

Thx mate 👍

[@three-phase562]

Fnirsi do deliver a lot if functionality for the price of their instruments. I have their SG-004A, which considering its price has exceptional functionality and pretty decent accuracy. They were quite good with technical support response as well when I asked questions. Just wish they would sort its measurement stability out, which doesn't seem to be an issue with this DMT-99.

[@KeepOnTesting]

That's a fantastic signal generator despite some hiccups. FNIRSI is definitely making a name for themselves!

[@barrybogart5436]

The onboard trend display is interesting. Too bad it doesn't have the log export feature too. How do you like your G-003a source compared to the LB02A? Yours is only $70Cdn, Tony tested a few of them. -4 and snow expected in Nanaimo!

[@KeepOnTesting]

Hey Barry, G-003 is very nice. I'm not entirely thrilled with the GUI command/interface but overall it's alot of technology for very little. It's got incredibly good battery life as well. I'll be reviewing it at some point 👉 -4 in Nanaimo eh.. Well +14C in Ottawa tomorrow and I do believe I see a palm 🌴 tree growing in my backyard 😅👍

[@ssalient]

This looks like a decent multimeter. Indeed a bummer about not being able to export logged data.

[@KeepOnTesting]

Definitely..it really reduces the logging effectiveness.

[@kandyvl]

I was looking for this model and stumbled upon another one which is Fnirsi S1. More interesed in this slim kind of multimeters. Looking forward for your review!

[@KeepOnTesting]

Thanks, I ordered the S1 for review, hopefully it ships soon.

[@Hartley94]

KE see your reviews.

[@KeepOnTesting]

Cheers !

[@pault6533]

Have you seen TRON?

[@KeepOnTesting]

Muhahaha 👍

[@8290Wgu]

very genius design , why fluke dont do like this

[@krasimirmitev2573]

Good multimeter, but what I will do after 2 or 3 years when battery is not holding its charge?

[@ruikazane5123]

You can get pretty much the same battery on a lot of Chinese sites. Or get a larger one if so desired even...

[@shaunmorrissey7313]

Change it.

[@KeepOnTesting]

Simply buy a replacement 803450 battery from Banggood or any other online vendor - 12$-15$. 👍

[@alfanarifin7319]

👍 ..good.. 😊

[@KeepOnTesting]

Thanks 😊

[@timothyurigwe8583]

If you could update your cheapo top 10 it would be greatly appreciated. I think the 620a is rated 3/5 stars would this rank higher?

[@KeepOnTesting]

The KOT Top Ten will be officially updated end of March,, stay tubed ! 😊

[@timothyurigwe8583]

@@KeepOnTesting Great to hear! Thanks Darren

[@nursaitaksu-yt1nr]

[@pault6533]

People have differing opinions about the beeping in diode mode. A beep indicates a short, so in theory you would only want to hear a beep if your diode is shorted. Is that how this unit responds in the diode mode? That is, no beep unless diode is shorted?

[@KeepOnTesting]

Correct. As far as the DMT-99 is concerned, no audible diode beep on this meter, period. Hence, no audible alert if the component is shorted. Too bad .. 🙁

[@pault6533]

@@KeepOnTesting thanks for the quick response! Unfortunately the bars on the display don’t respond quickly, that’s also a fail. Time for that software update!

[@KeepOnTesting]

@@pault6533 Oh yea Paul..not the most sensitive bargraph display for sure. Still lots to like for the price! 👍

[@tuber2kh]

@@KeepOnTesting Is that just for diode testing, or is there no beep at all, even for simple continuity checking?

[@mp1454]

🎖️🙏🏻👍🏻

[@KeepOnTesting]

😃 👍

[@deterdamel7380]

This could be a DMM for 3rd-party OSS firmware.

[@KeepOnTesting]

That would definitely be next level!

[@uni-byte]

8 Hz! Was that a joke? You seem to put a lot of effort into the post production work.

[@KeepOnTesting]

Thx.. I do try to take it up a notch production wise. My viewers deserve more than just a meh review! Cheers 👍
