EEVblog #112 – GSM vs The Fluke 87V Multimeter

[EEVblog]

Kiriakos, you have mail.
Fluke have said they'll be sure to get your meter replaced.

Dave.

Dave, I am so glad you did the fluke video without it, Kiriakos, would have a hard time defending his claim.

Kiriakos, I hope they replace your with a spanking shiny new baby

[PetrosA]

After all this joy , its my time for a Tsipouro .. 

Ahh this makes me thirsty for Greece I prefer a good dry Mastixa, maybe I will have to come over soon

Dave is the Godfather of electronics.

He just has to make a call, and it's taken care of :-)

It's 2010, email works a treat! 

In fact, all I usually to do is Tweet something these days and things happen!

While that is great news for Kiriakos, it does not *solve* his problem of having paid for a meter that is susceptible to rather commonplace EMI. Has there been any mention of getting the *problem* fixed properly?

Yes, but it's too early for specifics, Fluke will be looking into it.

put rhe meter in a metal case

Got it, and I am running like hell to send the DMM ( fast postal service), Got notifications from both,  Australia and Greece have all ready communicate about it.

Later the rest ...

I agree, the all story looks like news flash  it started  here  https://www.eevblog.com/forum/index.php?topic=1251.msg16290#msg16290  at 13-09-2010  

It took three days to be confirmed , so to stand as an case .

I contacted the Fluke at Holland at  13-09-2010  Holland called Greece at the same day ,
got my first email from them at 14-09-2010  , talk to them at the phone at 15-09-2010 ,
plus three days to be confirmed plus an dead weekend ( full of action for us     )  
its just 7 days so far ...  and the DMM started it travel today , at the seventh day .

Tomorrow its expected to be on Athens ( Fluke ) at midday  21-09-2010 .
Dispatches to Holland at the next day ( they do not have an reason to keep it )  22-09-2010

At this point I will stop speculating , because I am not aware if they will repair it or replace it.

And about the permanent EMI fix , my instinct tells me that they will need an month to resolve it.

The positive part are that at list there is currently awareness  thanks to Dave and the video about the 87-5 ,  and its the first positive step, on the right direction .

If some one else had proven the issue before I do , my DMM today it would be alive .. vulnerable but alive.  

Believe me, at this point its best to have an vulnerable but alive DMM, than a bricked one.  
And to have all the time in the world, to wait for the EMI fix .

Aaahh   it was shiny and sexy    even the one that I had ,
the only deference would be the original screen protector ( speaking about the new one) ,
as I had buy all ready from Ebay about 10 common ones as spares, enough for a life time  ...      

Thanks friend ..

[Kiriakos-GR]

Dave is it possible to run some tests over the  28II  ?

Other than the GSM , to be tested on 3G  and with he other sources that you have test the 87-5 ..

An reply in text will do .  
And complete video about EMI tests over the 28II , it would be ever better.
Its up to you , and your available time ..  

[Thermal Runaway]

Dave is it possible to run some tests over the  28II  ?

For your information, I own the 28II and I could not get anything dodgy to happen to it with my phone right next to it whilst making calls.  I also tried my wifi box and it was fine next to that when I streamed some video.

I think Dave is right.  The problem with the 87V is most likely due to some quirk of the PCB Design which makes it unpredictably susceptible to interference from the phone.  That said, I am surprised that the problem was not identified back at the Fluke labs.  I understand that they will not have used a mobile phone to apply a specific EMI test to the meter in the manner we've been describing but I'd have thought they would test it across a range of common frequencies for evidence of interference.  I've never been involved in these kinds of things so I don't know what sort of product EMI testing actually goes on.

I'll be interested to hear of an announcement from Fluke about this problem to see what they've found.

Brian

I believe that no one will ever see an announcement of what they will found ..

But I will tell you, what I have found ..

Instrument Description:
Fluke 80 Series V Digital Multimeters  
Memory Description:
Fluke 83 Series V, 87 Series V, and 88 Series V (83V, 87V, and 88V)
have one memory device:
U4, micro controller, TI MSP430F448, 48kB Flash, 1024B RAM,
contains operating code for the product and calibration constants.

AND

Instrument Description:
Fluke 2x II Digital Multimeters
Memory Description:
Fluke 27II and 28II
have one memory device:
U2, micro controller, TI MSP430F449, 60kB Flash, 2048B RAM,
contains operating code for the product and calibration constants.

Conclusion :  anything with the TI MSP430F448  its  " sensitive as device "  ,
I had describe it, as sweet as possible .  


CPU info : 8 MHz CPU incl. 16 Registers 

[Time]

Wouldn't this be grounds for a recall?

[Kiriakos-GR]

Wouldn't this be grounds for a recall?

It does , but I can no speak about the size of it .

At the  " technical thread about the issue "  I posted pictures of my PCB revision !!
An combination of the PCB revision with the micro controller TI MSP430F448,
it could lead in to interesting conclusions.

But I am not going to play the crime inspector ..

I am an professional technician and I need an healthy working tool with out issues what so ever .
Currently  the company agreed to offer me the choice of another model.
And I did accept it ..  
At the beginning of the next week , I will have more news .

That "conclusion" is simply bullshit. I know you write all kinds of junk here to get attention, so I won't waste much time with you. Just because they use the same MCUs doesn't mean they have then same susceptibility. You ignored basic things like shielding or the PCB layout.

If you ignored these basic things intentionally, then you are a troll.
If you ignored them unintentionally, then you are clueless.

Whatever it is, your "conclusion" is laughable.

I am not an God , but this is the only specs that are widely known ..

If you have an better opinion than my , let us have it ..

[EEVblog]

Kiriakos, make sure to let us know when you get your shiny new Fluke 28!

Dave.

[EEVblog]

Well, I guess that's the million dollar question.

The world's most popular multimeter that is a susceptible to the world's most popular gadget... who thinks that's grounds for a recall?

Extech didn't recall their pocket multimeter, and it was capable of killing someone!

Dave.

[RayJones]

They could SMS a recall notice and brick your phone in the process 

[Marvin]

Ok maybe this is not the right place to put it... but I turned on youtube auto transcribe and it is hilariously political...






Had no time for more screenshots (and coworkers where looking why I was laughing), but it continues on the same path...

you are getting mature as Dave's has, i hope i will be too actually someone here also reported that PIC is susceptible to EMI and want to build a Faraday Cage, sorry cant remember whos our pal is, you may find it yourself in this forum. So maybe Fluke has missed some basic thing such as shielding.

[Kiriakos-GR]

Kiriakos, make sure to let us know when you get your shiny new Fluke 28!

Dave.

I will do that 100%  

It just that , I am just a bit confused , because the Fluke Greece , told me that there is on the Fluke system , an replacement DMM ready to shipped as soon the damaged gets to Holland .
( So far so good )
But the replacement will be send from Holland too , and usually its  exactly the same model.
( Not as planed, by the representative that I had communicate with !!)

And the bottom line are that I will get an DMM ( Thanks God )    ,
but I do not know " what it would be "  !!

Thanks for identifying my true human side and motives ..

1) I am an technician and when I am having an conversation, I am thinking that I do that with people knowledgeable enough to comment , and even to find me as wrong , if I am so .

2) I have no hate in me for any brand ,  but I admit that I have my own likes and dislikes ,
like any one has.

3) I do not have any reason to flame FLUKE , the opposite ...  I am an poor man that I did discover the FLUKE products  at my second youth  ( 42 years old ) ,   end even if I nag about their pricing I had buy an pile of their accessories  and the DMM .  (Picture at the bottom that excludes the three bench type DMM that I own too )

4) This is not an court of law , so to decide what got wrong about the 87-5 ,
its possible the fault to be at the side of the company who supplied this chips to FLUKE !!  

5) and last , if any one finds the way that I can cash out my " fame " , I will split the profit 50/50 with him ..


Thanks for reading my rambling and sorry , if it was not needed , but I had to write it .
I am an man with pride ..
