10 Volt DC reference used in the video: voltagestandard.com/001%25-10v-reference
A good multimeter for hobby electronic projects should be able to measure millivolts, volts, microamps, milliamps, amps, ohms, nanofarads and microfarads.
If you want to measure picofarads, nanohenry, microhenry or reactance you will need a LCR meters. I cover the two LCR meters I own in another review.
I am not a professional, I am a hobbyist. This review is not sponsored; I bought this multimeter with my own money. I only used and tested this multimeter in CAT I and CAT II environments. I do not have a way to review or test the safety of this meter. I leave the CAT III and CAT IV environments to trained and licensed professionals. It may seem like I am a Fluke fan boy, but I recognize their flaws along with their advantages. There may be unintended mistakes and/or errors in this review.

can you review the BM2257?
Hello to everyone, I bought this multimeter and I have a question for UT181A owners when it is fully charged what message do you have on the display? It happens to me that I have a message charging 80% then 85% then 100% and it flashes like that. When I take out the charging adapter, the charging indicator icon seems to be not completely white. Does the same thing happen to you?
Here in the Netherlands a fluke 87V wil be EUR 799,00. There are cheaper alternatives so this meter in not populair.
It pretends to be like Fluke 18B+. The used name indicates that, I think. The're pretty much better fuses, than usually found 250V-fuses, are nice. Gives a feeling of more reliability. The used microchip is always the same in those cheap multimeters, it's the DTM0660L, this time in a normal IC package, not directly bonded onto the board.
I will say, Tom is one smart Man, and very thorough in his reviews!
Wow @ 01:07 😯 🙄
I have seen Energizer AAA alkaline cells leak. Does Dave send a tax invoice?
How does say a Brymen 786 compare to a Fluke 87V? I know it is a higher count meter but wondering if it is possible to compare.
Thanks for this detailed review. I also purchased this meter from TME. Amazing quality meter and retailer, received from Poland to NJ in about 3 days!
Sorry, but the max function doesn’t show you the “Inrush” Inrush is the first 3-5 cycles.. a few ms.. and the max function shows you the first full second roughly
I've been using the DT4282 since 2018, and it has worked perfectly up until now. In my experience, it's the best DMM I've ever had.
Its just a paint bucket with a coil. Snake oil Salesman video!😂
Hello I am wondering if you would be willing to do a video on Ham Radio for beginners.I am seriously considering starting this hobby and was wondering if you would do a video on the basics, like what is ham radio,course and test for technician,tools needed,things like that if you have the time Thank you,I appreciate your time.
Very similar to my UNI-T UT8804N, which is basically the benchtop version of this handheld meter.
Great review! I have the DT4282 and IMHO its a great meter.
LOL.. this is a unit made by CEM… it is rebadged for various brands: CEM DT951, Triplett MM650, Southwire 14070T, Amazon Commercial 90DM610, Peaktech 3445, etc… I have an Amazon Commercial 90DM600 (no LoZ and temp & flashlight) and it is a great little meter - very sturdy and solid, great for outdoor and rough terrain usage. Not an electronics meter but great for general outdoor usage !!! It is tested by Intertek (stamped on the back of the Amazon Commercial & Southwire units as physically verified by myself).
Very good, thank you.
Sir, your explanations are easy to follow. I love them! Please do some hobby circuits or electronics projects. My 18yo daughter is high functioning autistic (Formerly know as Asperger’s) and has shown an interest in electronics. I feel she would welcome instruction from you and this format. It’s not easy being a society outsider but she handles it as good as anyone. Electronics might be a confidence builder for her. Cheers, Kd5eag
Hi I’m Tom, I’m a fluke-aholic
Thanks for the review!
Хороший обзор😊 спасибо за видео
Hi Tom! I'm glade you've finally agreed to buy hioki one. I've risked my self too about a year ago and bought this one and absolutely love it! Thanks for your reviews!
Nice work. Hioki is loser for me- no bluetooth module ( FLUKE have IR3000, Keysight have U1177A, UNI-T have UT-D07A...), no bargraph, there is no possibility of adjustment in my country(only Japan), there are no instructions in Czech. This brand is as exotic as Yokogawa and Kyoritsu.There are no spare parts. And for Hioki: LPF can only be used on 600V & 1000V range, I am missing duty cycle and average (In some cases the filter function can substitute) and I do not know how useful 400 memory locations are.The user interface is slightly different to most other multimeters with min/max always active and a CLEAR to reset both min/max and peak without disabling them.
I'm really quite happy that you ultimately decided to review this meter despite not being third party safety tested. And better yet, that you'll be keeping it! For quite a long time I've been undecided on what I'll upgrade my generic $30 meter from Amazon with. I value your reviews and seeing the Hioki get your stamp of approval has really swayed me in this direction. I will say though that the included leads look a little disappointing. Hioki has a newer set of leads called the L9300 which comes included with their newer DT4261 meter. They appear to be much better leads in that they look more flexible and have attached sliding guards. It would be nice if Hioki included these leads with the DT4282 as well. If you're curious, you can see these leads in action in a CZcams video titled "[ENG SUB]How to Use HIOKI DT4261 TRMS Digital Multimeter- A Tutorial & Review (Part 3/3)" starting at 6:54. Thanks for the review! It was enjoyable to watch and listen to your thoughts on the meter.
Excellent review
Please test ut117c
What a lovely fella you are: Just enjoyed listening to you. :) Thanks for sharing.
I love my MacBook Air. I use it with SDR-Control on my 7300 and it's perfect for the Shack and when I'm in the parks. Looking forward to hearing your thoughts on the QMX radio! 73s! Andrew KE8WMS
I decided to buy once, cry once. My Klein multimeter was finally giving out after about 6 years of abuse and exchanging multiple techs. I wanted a meter I can call my own, put my name on and keep everyone away from. I went for the 87v Max with my education discount. I’m so excited to finally have my very own Fluke. I’ve spent a lot of my life around the meters because of my dad, never let him down. Now it’s my turn.
How long does a battery charge last in hours or so? and how long does it take to charge it afterwards?
Hey ,since your channel is new . I would love to know if you need any help with your subtitles for your audience in other countries. I can do it for you.
It looks like Space Black 😛 such a beautiful laptop!!!
I bought one last week. This meter seems to be the best way "to get it all" . The third diget might be wrong in some cases,.. - but who cares ? 😅 It has no practical impor- tance. At least not for me and probably for 90% of others users. Besides it's better than se- veral other meters out there.
the grandfathers of all electronics are coming out now on youtube. why did you not do it earlier before. don't be busy. 😄🥰🙂
Thanks for the review not only for this multimeter. I like the well performed tests and the comparison with the specification. I can imagine that the work for such review is hard. I appreciate your effort! I’m interested in the calibration circuits you have build e.g. the dc reference voltage shown starting at 5:00. do have a reference for the circuitries?
I did not build that reference I found it on Amazon: www.amazon.com/gp/product/B07SR9KTV6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 AD584KH High Precision 4-Channel 2.5V/7.5V/5V/10V Voltage Reference Module with Case at the YWBL-WH Store for about $22. I actually bought two of them and tested each with my bench meter, I picked the one with the closer values. If you want a pre-calabrated reference take a look at this voltagestandard.com/pentaref for $108, a bit pricey but I is much cheaper than buying you own bench meter, I already had the bench meters. You can specify each one of the five reference voltages from 0.1V to 10V. I did buy the 10V .001% reference they sell and I waiting for it to get here, they only ship USPS.
Thank you! Great presentation video!
Very good assessment of the MM720. Thanks for comparing to the other options.
Ohh I missed the sale would totally get one if it ever goes on sale again at Lowes
Master falto el modelo 88 V qie es el que yo tengo me hubiera gustado la reseña de ese modelo saludos desde Mexico 🤝👆👍👏🇲🇽
Tom, really enjoyed your reviews! i walked down slightly different paths so they are for yuks: 1. 189's: Had 3. including one I bought new in 2006. The 2 mint but used ones had intermittent glitches and could not be made to be stable and reliable. So the NIB, unused one with only minor fuzz around the SuperCap I sold to a friend who REALLY wanted it. I gave him a new SuperCap with it. I liked it but the SuperCap rotting away in it (and the 289) irked me. it turned out other meters appealed to me more in important ways so I no longer have one. 2. 867B's Bought 3 and still use one often. Larger stature but the bigger and much more legible screen (than the 289) and time domain display is excellent. Because it takes AC, it can be an infinite logger if needed. I only sold the 2 because they were less than mint. For about 15% more bulk, its superb accuracy (0.025% DCV) and very informative UI is not only superior (IMHO) to the 189 but also the 289. Its 3500mAH NiMH pack is still sold today and can be recharged in or out of the meter. Better yet, it can also take 6 AAs. Talk about hen's teeth, this was more difficult to find than the 189's but i like them more. 3. The one I reach for most often is not the 2 above but a Gossen Metrawatt Metrahit 29S. It's a 310,000 count, 0.02% DCV meter that has "Auto Select" function selection, runs on 2 AAs and is smaller than the 189 - about the same size as my first Fluke, the 79 Series II that I bought from Fry's 40 years ago. Still pristine and accurate to this day. The Achilles heel of these older Metrahit models is the lack of a backlight and perhaps a slightly slower response than Flukes. Calibration must be done at their facility and their prices, being "Made in Germany", make Flukes looks like bargains. But it's worth taking a good look if you can find one. 4. Had the Greenlee because I did not want to wait for the Brymen. To my eyes, the LEDs were too squished together to be legible like any Fluke or Gossen, and its claimed accuracy did not pass muster with my Fluke calibrator so it had a short visit. Long story short, my staples are the Gossen 29S and the Fluke 867B. Both dinosaurs but nothing made today is more desirable, can be relied on for dear life, or friendlier to use. I am on the lookout for a smaller meter that is easier to place wherever I want but one I can rely on just as much. It has not proven to be easy at all. Thanks again for your videos, they are very thoughtfully put together and very inspiring.
Mr. Tom, an excellent presentation and update, thank you!
Thank you for nice in-dept review. Look forward to your next video.
Great review. I have the Brymen BM 829S and has proven to be a great meter.
Thank you for the review.
This is my first meter ever, i hope i don't need another one
Isn't the 87v a 19,999 count meter?
Yes, in some modes it is, but increased resolution does not always mean more accuracy. The 87V manual states "For Model 87 in the 4 1⁄2-digit mode, multiply the number of least significant digits (counts) by 10". That means that it essentially is no more accurate in the 19,999 mode. Because of this I ignored that mode in my review. If you look at the best of the 10,000 to 20,000 count meters, they have better accurate specifications than the 87V in 19,999 mode. The 87V is a great 6,000 count meter but it is a poor 20,000 count meter. Fluke does not have a meter that competes in the 10,000 to 20,000 count range so they added the extra digit to the 87V without improving the accuracy.
@@N8FDY Let's take DC voltage for instance. 87v specs say "±(0.05% + 1)" UT161E states "±(0.05%+5)" what am i misunderstanding here? Isn't the 87v more accurate? Thanks
Thank you Tom !!!
It spans the right ranges for what I need. Happy I made the purchase. Thank you.
Do you think gold plated leads would change these results and make them more accurate if you were to buy this meter and upgrade the leads? For resistance that is
This will only help over time, because the gold plated leads will hold up longer. As long as you make sure you wipe that oily coating of the leads that come with the meter the leads should be good for a few years. People who do circuit tracing with continuity measurements prefer the cold plated leads. The meter met it specifications for the resistance measurements I tested. The accuracy is mostly controlled by the design of the meter. Instead of spending $35 to upgrade the leads, take that money and add $15 more and buy the EEVBlog Bremen BM235 instead of the MM720, that will give you better accuracy on the resistance ranges. In my testing I use the same test leads on every meter, I don't use the leads that come with the meter, I want to test the meter not the leads.
I think you are right, 87V max is a better meter in this category/price range. I think the Keysight U1282A is a better choice than the Fluke 289 but it does retain some of the things you don't like.
