content: Quote from: HKJ on April 25, 2018, 09:26:17 amIt would be good to know which meters you like the most. Not necessarily based on their specs or technical merit, which meters you like and enjoy using.ie. When you need a meter, which one do you instinctively grab?Which meters are languishing in a drawer and will probably never see the light of day ?You could maybe have three categories with a couple of meters in each:Hobby meter, not safe for mains work but fine for low voltage bench work.Safe for mains work, certified CAT rating.Overall favorite meters.

content: Quote from: Fungus on April 25, 2018, 03:29:36 pmMostly I like and use high end meters:Fluke 179: A fairly simple meter (Compared to the ones below), it has never been my primary meter, but often get used to check stuff.Fluke 189: My favorite Fluke meter.Fluke 289: It is good for something, but it is slow to turn on and has low contrast on the displayGossen Metrahit Energy: I bought it because it could measure power, but I also love that it auto ranges from uA to 10A and you never blow a x00mA fuse in it. It has often been my favorite meter for measuring current, but now I have a power supply with a very good current readout and some bench AC power meters, this means I do not use it as often anymore.Keysight U1252B: I have been using that for some time, it has a silly layout with the buttons and the rechargeable battery got swapped with a primary before it was empty first time.Keysight U1282A: I have been using this a bit, but I am not very impressed with its speed.Hioki DT4282: After my review I decided to try this out as my main meter, I like the speed of it.Many of the meters has also been used for logging with a computer, this means they have been running formanyhours, but mostly I have changed to bench meters for this.In the multimeter table on my website is a rough safety evaluation of each meter (You can sort on any column)

content: Hi HKJ,Really nice work. I like your reviews. I read quite a few of them. They are concise and from a practical point of view. I like that you have not censored the drawbacks/bad points.It has been said countless times that the user of such an equipment should learn how to use it, its shortcomings and its limitations. But unfortunately the manufacturers hide such information and not everyone has access to a full blown electronics lab to understand the behaviour of such equipment and such reviews help a lot. Please keep it up.May I request you to post reviews for your Fluke 189 and 289. The teardown for these is not that necessary (as you may not want to take them apart) but I was hoping for their reviews along the lines of your Brymen BM869s and Hioki DT4282 reviews.Regards,Qasim.

content: Quote from: mqsaharan on April 27, 2018, 08:29:13 amI am a bit in two minds about that, all the meters I have reviewed above are new and I can also show what you get with the meter.I have some high-end meters and the technical information for them could be interesting to include, but a review of a old meter is not the same as the review of a new meter.

content: Quote from: HKJ on April 27, 2018, 09:28:40 amI understand your hesitancy to include old/used meters with new ones. But keep in mind, it seems most of us try and utilize the used market whenever possible. So reviews of older meters such as the Fluke 189 & 289 have merit IMHO.Determining which ones to include would be the hard part, but suggestions from various geo-locations should help narrow that down considerably (and someone may be able to donate a specimen for review).For clarity, you could always separate them in NEW & OLD lists. Any personal usage comparative comments would be appropriate in the conclusion section.Just a thought.

content: Quote from: HKJ on April 27, 2018, 09:28:40 amnanofrog has already put my reason in better words. I am just repeating what he said.I requested for their review Because they are used and since You are the original owner you can give better comments on their true (and not assumed) quality.You can also compare their deviation (if there is any) from the "Production Verification Test Data" that you received with them against their current display readings using your higher precision and higher resolution bench meters thus telling us how they held up with your usage, etc. (just another thought).Regards,Qasim.

I appreciate your efforts.I was more interested in the working details of this meter that you presented very nicely.In your reviews, Summary table is very useful to see most of the specifications at a glance.Would you kindly tell me what is the difference between True RMS and True AC as there is also a third box AC+DC? Also what does Fast means or refers to.If you would like you can add "On/Off Button" to the empty box. There are only a few handheld meters left that have a dedicated On/Off button.Regards,Qasim.

content: Quote from: mqsaharan on August 02, 2018, 04:57:55 pmWith True AC means the meter can handle a large DC or AC while measuring the opposite typeThe AC+DC means the meter can show the RMS sum of AC+DC.Quote from: mqsaharan on August 02, 2018, 04:57:55 pmThis means the meter has a mode with fast updates and usual less resolution (This is mostly for bench meters).You can find a explanation of all the items and a bit about how I test here:https://lygte-info.dk/info/DMMinfo.htmlQuote from: mqsaharan on August 02, 2018, 04:57:55 pmThere a some parameters that I do not really see as significant, the on/off button is one of them, (non)latched continuity is another, that is the reason they are missing in the schema.

content: Hi HKJ,I was reading your review of HIOKI DT4282. There seems to be a mistake on 2nd line under Measurements, Volt and frequency. The line reads:"At 100mVrms VAC frequency input range can be stretched to 500MHz that is maximum for meter."The upper limit I think is 500kHz and not 500MHz.In your Brymen BM869s review, may I request for a little more explanation regarding point/line number 12 under Measurements, Volt and frequency. It reads:"Large AC values on DC ranges will prevent the meter from showing a value, except if dual display AC and DC is selected."Could you please mention how large an AC value on DC range prevent the meter from showing a value at all. Also is the behaviour same for line frequency 50/60Hz and lower/higher frequencies.And for the line number 15 which reads:"The DCV & DCmV range has two paths: Directly DC volt and True-RMS volt, they will not show exactly the same value. The 500000 read out the direct DC mode."Could you please mention the difference between both values. Also which mode shows (closer to) the actual value.The same is true for BM525s review.Regards,Qasim.

The actual difference is about 6 count on 1 volt DC on my BM869s

content: Thanks for the clarification.Quote from: HKJ on August 15, 2018, 07:42:04 amI did visit the "How Do I Review a DMM" page but I didn't read it thoroughly, gave it more of a cursory look.The reason I asked the question was I thought you have some variable source for AC and DC and you have been feeding the meter with different voltage levels when you found that anomaly.I guess these meters work all right at low levels otherwise many users have complained about it.Quote from: HKJ on August 15, 2018, 07:42:04 amI guess nothing to worry about here too. The meters seem within specifications.My suggestion is to please do mention this difference of 6 counts on the review pages, makes it more clear.Regards,Qasim.

They are considerable more expensive than Aneng, but you get a much more robust and safer meter for the price.

content: Quote from: Jorge_dPO on December 02, 2019, 09:28:08 amIt is the top meter in the 25x series and have a good selection of ranges. It is also well protected and Brymen meters can last a long time.A few comments to the specifications:It will warn you if probes are in current ranges when selecting voltage measurement, this is a nice safety.If you want to check mains outlets or voltages, the low-Z function can be very useful.The computer interface is extra, if you want to log measurement over a couple of hours this is a nice extra.The meter do not have average (You need fairly high end meters for that), it can be useful for measure average current consumption on devices where the current varies.The frequency only goes to one 1MHz, I will say that is more than enough, a multimeter is not for measuring RF.It is missing duty-cycle (The best meters for measuring duty-cycle (PWM) is usually the cheap meters without much input protection).The capacity range is limited to 3000uF, this means it cannot test large electrolytic capacitors, usually this is not very important.

content: I just like to play with electronics and sometimes make some electric repairs in the house and my motorcycle, so it isn't nothing serius, thats why i was thinking about the 139E, because it have a more or less good protection for main voltage.

content: Thanks for the info, i probably will buy the aneng 870 or de ut139e, and then start saving money for a Brymen, maybe the 829s?By the way, the AC + DC function, when can it be used? It is useful?

content: Quote from: Jorge_dPO on December 02, 2019, 11:51:14 amIt will measure the total voltage. Standard for multimeters is to filter and only show either the DC or the AC part, the AC+DC combines the two into a single RMS value. In some cases a function that shows both AC and DC values simultaneous is more useful.Neither is required, you can always do two measurement and do the match yourself (It isnota simple addition).

content: First and foremost I'd like to thank you for doing those reviews. It's pretty nice to have a detailed look on that variety of makers and models.As a suggestion, have you thought about listing models that are based on a same platform?

content: Quote from: LeonR on December 03, 2019, 03:06:13 pmI cannot remember all the meters, this means it would require some extra work to check the specifications and tear-down photos and I do not see it as a very interesting detail.

content: I really like your review page. It's great that you keep the format essentially the same for all reviews, that makes it very easy to compare 2 different meters.

content: This is a great multimeter review resource. Thank you very much.I had been looking at theBrymen BM869s, but it seems theGreenlee DM-860Ais generally more available in the USA (maybe easier to get proper warranty support in the USA?).https://www.greenlee.com/us/en/dmm-500k-counts-dm-860a-calib-dm-860a-c?w=2&c=167&b=86&t=6&r=30&p=1&lat=37.362107&lng=-121.982035&l=4&v=chttps://www.tme.com/us/en-us/details/bm869/portable-digital-multimeters/brymen/bm869s/?brutto=1From the reviews linked from this thread, it appears that the MASTECH MS8218 quality and design may not be as solid as the Brymen or Greenlee?I guess one could buy the Brymen BM869s here ($270?):https://www.welectron.com/Brymen-BM869s-Multimeter_1But then the warranty might be an issue

It's certainly less than $100 of risk on your part.(if it's DOA then I don't think Welectron will let you down)
