    Learn about reading current in a circuit.

    Your little suggestion that I read the definition of the word shunt
    backfired too.

    Run home and cry now, little baer... errr... boy.

    Ahh... so you're a double posting dope too!

    This dope is still running windows 98!

    How would you know without a reliable device to check it against,
    dipshit?

    I'll clue you... the extech ain't it.

    Bwuahahahahahaahah!
     
  4. Oh really? And just how do you figure that? It's brand new and it was
    available with an NIST certificate (though I didn't opt for it). I guess I
    need to send it to you so you can verify it against your Protek?

    I told you, dumbass, I have a calibrated HP 3478A.

    The protek is ANOTHER meter I have, and I use the HP to verify it.

    Your NON NIST traceable and certified Extech is calibrated by an
    assembler that was working enough years to end up in the production
    test lab.

    Their prime pass yields are likely far less than 90%, and 96% is
    considered poor. Yes, you'll have to look that one up.

    I'll say it again...


    Bwuahahahahahahaha!
     
  7. At least you didn't touch it.
    Funny how it can be sent in and certified after the sale. I wonder how they
    know who to send the good ones to. These meters you have at home, what do
    you use them for? I mean I never see a schematic from you or hear of you
    tinkering with some kind of experiment. Why is that?

    Anything can, you fuckin' retard.
     
  9. You don't even know when you are being made fun of!
    At this price and accuracy level it is almost certain that every unit
    would be automatically factory tested to be in-spec, so the NIST cert
    is worth the paper it's written on. You can bet the farm that
    Anthony's new meter meets the published specs.

    Idiot! His meter is NOT certified. Learn to read.
     
  11. It comes with specs, they always apply. Wasn't it you that said that certs
    were often just a check not necessarily turning screws? If the meter said
    Agilent or Fluke on it, would you even be mentioning this? How come you
    didn't say anything about the RMS convertor behaving the way I described? I
    thought you were knowledgeable on this stuff.

    Cal Certificates just state the instrument was calibrated using known
    standards traceable to NIST,the date the work was done,temp and humidity
    conditions,and the recommended cal interval.They may list the standards
    used and their expiration dates.
     
  13. Finding the keyboard operational
    MassiveProng entered:
    Youu do realize that calibrated and certified are not the same thing, don't
    you? You could have your HP 3478A certified to +/- 10% VDC.

    My first meter cost five times that, was analog, and only had 20K ohms
    per volt.

    For those young folk who aren't familiar with that, yes, the meter input
    impedance changed depending on the range you set the meter to.
     
  16. My first meter (a cheapie my dad's friend gave me when I was about 10) was
    in that range (could it have been 10k?). The better meters I had in my
    younger days were a whopping 50k ohms/volt.

    Check; the neatthing is that on higher voltage scales, the input
    resistance exceeds that of a DMM.
    Which is why i built a voltmeter/currentmeter around a 5 microamp
    movement giving 200K per volt sensitivity.

    I do remember seeing one of those 50K/V meters whan i was young; what
    the heck has happened to them?
     
  19. Mine was 2K IIRC. I still have it.
