"It was a fluke !" 🤣
I absolutely love my 189 daily driver and it's easy to see by your tests why it's still kicking after all these years of abuse. Thanks Joe for another fascinating video.
Thanks for the video and the efforts behind these tests.
This looks like the big daddy of the high entry multimeters that are now spread for other brands. Thanks for the tests and good information.
Excellent analysis and great explanations, thank you very much for your work!
Only time I seen someone fry a Fluke 189.. They tested a Neo sign transformer. On the load side. He got the shock of his life at 20k volts...
LOL!!! There is a really good video of a guy rebuilding one after a co-worker damaged one. I recommend you check it out. czcams.com/video/DUwkuM3blsk/video.html
Sir, you are a treasure! Thank you.
Very informative test.
I couldn't find any tests done by you on the Fluke 179.
Would be nice to see how it behaves.
Thanks.
I doubt I will look at any more Fluke meters unless they come out with something new that is of interest to me.
The best Fluke DMM 👍👍👍👍
Hi Joe I love my 189 It's the pinnacle of my fault finding world! (30+ Years), fantastic work on the schematic front end and component Id this will be hugely useful. Apart from me pausing the video and drawing it out, do you have any schematics of the 189? or your Input tracings?, Many thank's and superb info, and I'm subscribed cheers .
Video is a few years old. I doubt I even saved that section I drew up. For a full schematic, I would contact Fluke. I doubt they would release them but you never know.
Can you provide a video on how to remove pen marks on the fluke 189 meter? would appreciate it very much...
Joe, I would recommend getting the BP189 battery option.
Why? It's VERY bulky. I have bench meters that I used for long term logging. I installed NiMHs into my friends old 189 when he gave it to me and I have yet to recharge them.
Hi.. love your videos... I wanted to ask if you ever do repair work on meters for others? I have a Fluke 87IV, which is my favorite meter that I own... but it needs a new buzzer (listed as discontinued on the Mouser site, and I need that buzzer for the work I do), and I'd love to have it checked and calibrated... Also needs the plastic stand piece. But I work on audio gear, and am hesitant to work on the meter, lest I make the kind of mistakes you mention in this video... Anyway, I'd be grateful to have it worked on by someone who knows meters inside out, and you seem to be the best in this regard (and no doubt others as well)....
Sorry but I do not offer any repair or alignment services.
Joe is a fixable a multimeter when it reads a low ohm value in resistance scale ?
I threw away my (ex) Fluke 189 because the local fluke service isn' t able to fix it or calibrate as well
I would imagine anything can be fixed given enough resources and time. It may not be cost effective but that is not what you asked.
hi are you going to make a full review of the Fluke 189?
Hello. I have not planned on it. These are a very old meter and have not been available for many years. I do use them from time to time in various videos as a comparison. By far, this model has been my favorite Fluke. It's just a good all around basic meter, like the Brymen BM869s.
Joe, Which Belkin screen protectors did you use? Did you buy a tablet protection sheet and trim to fit?
This is what I used but I would not recommend them in some cases as they are very reflective.

I covet this and Brymen 869s. I'd also like to replace my usb oscilloscope with a tektronix, but i have to be realistic about my electronics needs. The pleasure in using good tools shouldn't be understated.
Very true!
Joe: Where is the SUPERCAP you replaced? I have collected x4 189's and x2 289's; should i be looking at this cap in my meters?? I chose the 189 years ago due to dB-ref impedance is adjustable from 0001-1999 (wheras every other meter I considered that had variable dB-ref impedance forced you to select from STANDARD VALUES only). Over time, I fell in love with the 189 (and cheat on the side with the 289). Your videos are very well done -- love the details. I will try the Meguiars PlastX, as the Novus has left me wanting more. Thank You.
It's in the trash bin where it belongs. There have been several YT videos made and various posts showing the supercap problem. I destroyed a Lenovo tablet over the summer when the supercap leaked all over the board. I checked a second tablet I have and sure enough, it was just starting to go. On the open case meter shown in the video, you can see I already removed it. Personally, I would check them.
I check mine, but I still have 6 years left on the warranty so if it leaks I’ll send it in for a replacement. Most of the time if you don’t catch it just starting to leak it will ruin the traces on the PCB. Not sure why they still used this in the 289 since they knew the 189 had this problem.
Highttech- As for the location on the 289 you can see a close up of the SCAP and a full HD picture of the PCB on my photo bucket.
I also have a few others things in this public folder like the fluke 86B series II pictures.

@@joesmith-je3tq and Gadget Review:
Thanks for reply. I shall look into this SCAP tomorrow. Perhaps mine will join Joe's "In the trash.." soon.
(edit) Just ordered
604-1147-1-ND from Digi-Key. Forums and Digi-Key recommend as replacement for OE cap. Joe, did you use this one?
hightech, no that is not what I used.
@@joesmith-je3tq : Where did you get the cap you used, and what is part number? Also, in your opinion, are the Digi-Key caps I ordered suitable replacements? Thank you for the help.
My daily meter. I can't complain about it.
Hi Joe - You mentioned the Belkin screen protector, wondering which one you used as I have a brand new 17B+ and would like to
install one before it gets any scratches on the window - thanks -
I would just see what your local office supply carries or check on Amazon. I posted about the film on eevblog. Their search should find it. The glare can be a bit much and you may like the frosted ones instead.
Agreed, I see they make anti-glare versions of the film. I registered on eevblog looks like a nice forum/community - astounding as it sounds I do not own a smart phone so wondering what iphone screen size I need to be big enough to size for the 17B+, just dont want to buy something too small. Really like this new 17B+, though the MOV's and PTC's seem kind of small and the price may be a touch high at $130 but otherwise it works perfectly and the seller printed up some manuals in english he ships with them, nice touch. It still has a quality feel even though its of chinese manufacture. I saw some on ebay for around a hundred but the sellers info looked sketchy - this one was already in the US only had to wait three days for delivery.
I made a video where I life cycle tested the 17B+. Still the bast switch I have looked at. Input protection seems a bit weak by Fluke standards but it still out performed the vast majority of products I have looked at. You can find the product I used on this page. Pictures will give you some idea how it looks.

This series of FLUKE 189 videos put a 189 on my Meter Collection list. Found a nice one on eBay. Had to polish the face but otherwise pretty good. I thought it was defective in the Diode Test function... Turns out there is no diode symbol on the display. Rather odd since my 1983 Fluke 77 has one, as I think, do all my other Fluke meters. Hmmmm...
I ended up buying one for the case as a parts unit. As it turned out, the meter was fine. Clip showing measuring capacitance. Hard to believe these are this tight after so many years.

Thanks for your Videos. They are made well and they are super informative for me. I like the 189/189 II but, I leave in Bulgaria and is really big problem to get something from USA.
Can you give me some advise what is the price for good condition 189 ? What to watch when I search in E-Bay for the model, any advise will be helpful.
Can I get good one for around 100-120 USD ?
Also can you help me with Capacitor problem (like number, brand or model of it).
I study electronics and microprocessor in my mid school. Now I study Electric engineering still work on electronics but not so often like before.
Thanks for your time and sorry for my bad English.
I see the Fluke 189 normally going for around $200 - $300 depending on the condition. You may stumble onto a $100 if you are lucky. For the capacitor, watch czcams.com/video/8t8nkCbYJVc/video.html In this video I provide details on the parts I use.
I'm half sleep now, but you show many times the scope is set 100uS/div but say FWHH is one div and 50uS. That's with the programmable generator. What am I missing?
That's not you that's the problem. You will see that the spreadsheet is 100uS FWHH, which as you mention matches the scope. The problem is just me being on autopilot, running through the motions and not thinking about what I am doing.
im sure you get this a lot but what is that power supply you use for the 1kv DC and AC tests?
Custom
thank you
if i´m correct i can actually measure nanosiemens even on my old fluke 87 serie III. according to manual that range is used for components with up to 100 000 Mohm. there is also something in the manual about measure the dc offset of a ac voltage. but not sure what they mean, have never used that "function".
As a sidenote, bought that 87 in 1998 if I remeber correct and it still works very good.
But to be honest, a dmm is not very usefull when working as a installation electrician. a simple voltage detector is for 99% of the time enough as long as it has some kind of ohm readings and continuity test besides ac voltage.
Everyone is talking about the age.. what year the Fluke 189, 289 and 87V were released?
Are there some new technologies that make the new multimeters (like Fluke 289) much better than 189?
I'm sure you are smart enough to look up the release dates as well as compare the features of the 289 with the 189. Odd you would consider the 289 new.
@@joesmith-je3tq thank you, Fluke 189, August 2000, Fluke 289 June 2007, Fluke 87V May 2004.
@@joesmith-je3tq They just compare specs, they don't teardown to compare technology, I asked if you found some new ICs, etc.
@@JohnUsp 13 years ago, we may have said there was some new IC's but not today. These meters are all fairly old. I don't think the average electrician buys a Fluke to get the latest technology. Support, Safety and reliability may be more what they are after.
@@joesmith-je3tq Wow, for you what multimeter best achieve those qualities?
Standards are even different across different countries.
But basically they are made from user safety point of view.
If companies wanna go further (like Fluke) that's on them, but they don't have to.
You also have to put all of this in a professional context. Even most engineers will only ever reach CAT III. (But in general no more than CAT II)
Again it depends per country, but for CAT IV people already need a special license plus in most cases people can't even have access to those circuits.
As I understand, they are guidelines and not requirements. As I understand it, the CE mark is self regulated. As I understand it, even if a product were certified with the same mark, it may be tested differently depending on the country were it was certified. As I understand it, if you were to have a handheld meter certified in the US by UL for the 61010, they will hold you to meeting that standard.
I really have no idea how many engineers or otherwise work in various environments or what the prerequisites are. Again, I really don't even care about the 61010 standards as far as if a particular handheld meter meets them or not. Certainly nothing I show on this channel has anything to do with them.
Standard requirements are different among countries, but the standards themselves have very little variations across the globe. Part by the fact that several industrial countries are signatories of treaties to create equivalence among standards.
The CE mark itself is self applied, but the LVD directive 2014/35/EU carries a mandatory minimum safety requirements for "electrical equipment for measurement, control and laboratory use", which is the EN 61010 (the one more specific to DMMs is the 61010-2-033:2012). In other words, you can apply the sticker as much as you want but, if you are caught, you need to provide proof of compliance to the standard.
If you are caught? Caught doing what?
joe smith Caught not meeting these standards.
While most standards are the same or equal in many countries, the way the laws applies to them is very different.
In some countries every manufacture has to go through mandatory tests, in other countries this responsibility is actually in the hands of the manufacturer. (like Vbe said, the CE mark is self applied)
Samples are being investigated from random manufactures. If these tests show that you don't meet the requirements you have a certain mount of time to fix these issues. If you can't, well in a lot of cases it means filing for bankruptcy since the fines can be huge.
Not to speak about the damage in trust among your consumers.
My other comment was about that I don't understand that there is so much to do about meeting the highest CAT ratings.
In a lot of countries people can't even reach areas with these higher CAT ratings, since you have to be certified to even have access to them.
(as in needing a key or similar that grants access)
Joe, as Piet mentioned, if you are caught trying to sell the product on EU. Last time I checked, among the signatory countries this liability falls into whomever tries to sell the product in the EU, either the manufacturer or a broker/rep/distributor.
Are you saying to remove the supercap and leave it out?
Yes, remove the supercap and leave it out, do not replace it. I use the Fluke 189 together with the BP189 and the C-cell batteries last for years and years.
In the video, I said "replaced" which is what I did.
will you tell us the part number?
I have had the 189 rarely used since new. I have heard of these supercaps failing, but I have not even opened it up to inspect it.
I am seeing some are replacing and some are removing. Should I just replace it anyway, leaking or not. What would be the best option? If I should replace, is there a preferred part number to get?
👍👍
Você venderia o fluke 189 ?
Sorry, this channel has no products to sell. You can find used 189s from time to time. Good luck with your search.
Fluke 189 ou 289 ? Qual indicaria ?
@@teccellcelular9343 I think you are asking which I prefer. Personally, the 189.
Boa noite de portugal
Good night
Где можно такой купить
They have not been manufactured for many years. You would need to look for a used one.
Ясно.спасибо!
Но приборы не смотря на возраст классные!
Bom dia
Fluke 189 is 18 years old???
It looks like all of the manuals Fluke has on-line for it are from 2000. 2020-2000=20? Could be older.
joe smith between this and 117 which one do
you recommend??
@@OKTAYAlizadeh I recommend you read the FAQ.
