Death & Destruction of a Fluke Multimeter

  1. The title says it all really.
    See what happens when I try to destroy Fluke's new 28-II Multimeter:

    Ha! I thought you tied the multimeter to the back of the car and dragged
    it down the freeway. :p

    Stopped at 3:20min. Had to continue life.

    Got interesting up around 10:00 or so... 30 meters eh?

    Screw you Dave, I wanna see that thing under a sledge. :) Or maybe a log
    splitter, or backhoe, or something...

    He got it for nuffin just to test.
     

  5. If you had seen some of his earlier videos, you'd know why. By all means use
    your cheaper meter if you like, but there is such a thing as, "measurement
    confidence". If your work is important, perhaps with lots of money or even
    someone's life potentially at stake, which meter would I rather rely on? I
    think the answer is pretty obvious.
    I own meters large and small, el cheapos and better ones. But when I really
    need to know, right now and with no bullshit, I reach for the Fluke.

    Nice field trip. Most impressive !
    I did think that the LCD would have broken much sooner though.
    The inductor failure could have been prevented.
    Good one.
     
  7. If you had seen some of his earlier videos, you'd know why. By all
    Fluke.

    I bought an expensive Fluke multimeter 20 years. It continues to work well,
    and has only needed to have the LCD contacts cleaned (twice). I'm almost 63,
    and if I live to be 90, I expect it to continue to work.

    Harbor Freight sometimes sells their cheap multimeter for $2 (!!!). I gave
    one to a friend for Christmas, because he needed one for occasional work. I
    can see taking such a meter into places it might be damaged or destroyed.
    But I wouldn't use it for daily work.

    More multimeter torturing:
    Here is report about those $5 multimeters

    Better to stay away from mains with those.
    I learned that hard way when I measured a water heater with some unknown
    cheap meter.
    First measured phase-to-ground 230 V fine... then phase to phase BANG
    instead of 380 V
    Fortunately only 16 A fuses on that circuit, so only damage was charred
    multimeter. Think
    if someone were dumb enough to measure something protected with 250 A
    fuses... Like
    if he forgot his own meter in car and sees nice looking meter lying
    somewhere and actually
    believes the "CAT III 600V" text printed on it. "Well, this meter should do
    the job" and then
    it shorts in his hands at about 1/10 voltage CAT III meter should withstand.

    My AUD$3K Fluke PM97 failed from normal use. The batteries wouldn't
    hold a charge from day 1, the AC adapter failed after only a short
    time, one of the probes failed soon after, and then the meter itself
    failed. The service manual was missing the power supply page (maybe
    some Fluke/Philips tech used it and forgot to replace it).

    One day I'll step on it ... again, and again, and again.

  12. My AUD$3K Fluke PM97 failed from normal use. The batteries
    Then why wasn't it repaired/replaced under warranty?
     

  13. Well, Fluke Australia had given it to him to review, and they said he could
    torture test it. The new models 27 and 28 replace the previous models
    renowned for their ruggedness, so I think it makes sense.

    The 100 foot drop onto concrete left my jaw hanging wide open. Then he did
    it AGAIN without the rubber holster...oh, my.

    Want to bet they put a little RTV on those inductors in the future?

    A bit like kicking kittens?

    ;-)
     
  15. Precisely.
    The unit isn't just sold as regular multimeter, it is specifically designed
    and marketed as a super rugged meter that is designed to survive abuse and
    water ingress, just like the original Fluke 25 and 27. If that wasn't the
    case you'd just buy the identical model 87V.
    So to NOT test those aspects would be a poor review indeed. And then to only
    drop it from 3m where I know it's going survive is kinda pointless. So it
    makes sense to push it and get a meaningful data point at which it does
    actually break.
    My jaw was equally wide open!

    Dave,


    You should make what was left the prize in a competition.

    Amazing. I doubted the 3M drop spec. Not any more.

    I bought it in Australia, but I took it to Singapore. I suppose I
    could have made the effort to have the batteries replaced, but I
    relied on the AC adapter, until it failed.

    More tests beyond specification:

    Drive over it with a car.
    Drive over it with a heavy truck.
    Have good athletes kick it into a concrete wall.
    Put it into a cement mixer running for 10 minutes (first dry then with water and finally with concrete).

    Well, how do you get around using a reflow oven or some other soldering?
