Fluke 8060A Suddenly Not Working

  1. I have a Fluke 8060A (True RMS) DMM.
    Okay, after about 8 months, I dug out the meter and turned it on to
    find that it is working again. ?!?

    That doesn't sound like a cold solder problem or a battery connector
    problem, because if it were, would it have exhibited intermittant
    operation when I was messing around with it last year?

    Nevertheless, anything that happen once can happen again, so I'd
    appreciate some ideas on what the problem might have been.

    I don't think getting it professionally worked on is worth it because
    these meters can only be gotten used, and it cost more to get them
    repaired than to just get a used one from Ebay.

    Thanks a lot.

    I had one of these that did the same thing to me.
    It'd go on and off with any type of movement etc...
    While I don't recommend this type of fix I gave it a firm flat
    slapdown on my work counter.(Not hard enough to cause case damage.)
    After that it hasn't given me any problems.
    That said the correct way to go about fixing the problem is to open it
    up and look for cold solder joints or loose wiring.
     
  3. I had one of these that did the same thing to me.
    I don't believe it is the same problem I was having

    My meter was not working at all, regardless of how much I slapped it
    around. I left it untouched for months, and now it works
    100%.(Regardless of how much I slap it around).

    I don't believe that cold solder will correct itself like that.(But
    correct me if I'm wrong).

  4. Could it have been some environmental issue like high humidity or cold
    temperature?

  5. Well, I do reside in New York. :) But the meter was always kept in my
    room. I just wish I new what the problem was so I can take
    precautions.

    It seems that resoldering at this point would constitute a shotgun
    approach at best, that could end up trashing the meter instead of
    being preventative maintenance.

    When I was having that problem with it last year, I won another one at
    auction for $35, which is about $100 less than the first one, and also
    much, much cheaper than it cost to repair these meters. :)

    Anyway, I want to just sell or trade it, but can't until I am sure the
    problem won't resurface.

    Here's something I didn't think of.
    These meters have a self-check startup routine and if you have a weak
    or defective battery it can cause false test results.
    I had this problem with mine once. It'd power up get in the middle of
    the self check then cut off.
    Problem resolved itself when I replaced the battery.(The bad battery
    only read 6.5 volts even though it was new.)
     
  7. Here's something I didn't think of.
    It seems as though the problem has reared it's head again. The meter
    comes on, but the characters only partly show on the screen. So it
    seems like it is a power problem.

    I did notice that the meter tended to eat batteries like crazy. I'll
    have to try differnet brands of batteries to see if the problem is
    solved.

    Thanks.

    I sold a dead one a few years ago. Fella that bought it said it
    needed a voltage regulator chip. I had a couple more and
    wasn't interested in fixing it myself...Paul
