    I've been given a Megger (500V Hand Generator), it's not
    actually a Wheatstone bridge, but it does do the Varley
    Bridge measurement.

    Resistance measurement from MegOhms to MilliOhms!

    I've already got one, which I use for accurate resistance
    measurement (Box is about 9" cube) and I don't
    need another!

    Free to a good home!
     
  2. Very generous, but why not put it on Ebay and donate the profit to charity?

    If you can't be bothered, I would happily put it on for you and send you
    the link so you could see how much it made and send you the charity
    receipt for the amount it got, less postage and listing costs.

    If you haven't ever sold anthing on Ebay - why not make this the first?

    I am opposed to organised charities which are a means
    for the paid officials to pursue what is essentially their
    hobby, but at the expense of money that we might
    otherwise be putting into our own hobbies.

    charity?
     
  4. At this moment, there ar rain clouds moving southward to Port au Prince,
    Haiti. When they get there, in a few hours, the rivers will carry all
    the rubbish and sewage from the whole city into the slums of Cite
    Soleil. The shacks typically fill with raw sewage to waist-height and
    parents have to stand, holding up their children, for the hours until
    the water subsides. There is no high ground to run to. Apart from the
    area around the President's Palace, most of the city gets electricity
    for a couple of hours a day. Cite Soleil gets none at all, so people
    have to endure this in total darkness - year after year after year. I
    can picture it because I worked there, pursuing my hobby working as a
    volunteer for an organised charity..

    And from what you say, you made no difference
    at all to the emotive scene that you describe; because, as
    you say, this still happens year after year. (Despite
    that you were pursuing the hobby that made you feel
    good at the time, and that, seemingly, makes you feel
    self-satisfied today.)

    If I wanted a break in foreign parts, a break that would
    make me feel good, then I'd expect to have to pay for
    it myself.
     
  6. Will it measure polarised resistors?
    MILLIOHM measurements with a 500V generator???
    You're always saying you build all your own gear.
    Will require de-lousing and fumigation.

    That is why he has the "Big M" correction factor (or did he mean
    milliOhm?)

    Not to mention the normal name for the bridge used to measure low resistance
    being he Kelvin Bridge (note the Big K).

    It was, at one time, sometimes known as the Kelvin-Varley bridge but things
    have developed a bit since then.

    I see that FRANCES TURNIP-SMELLY remains as
    infantile as she has always been, and also displays
    her ignorance - for the milliOhm readings, the generator
    is applied to a bridge circuit. (I believe FRANCES to be
    one of life's failures who went to the "University Of Life"
    but who came away without a degree)

    I see that Mr.Reay cannot resist an opportunity to
    sneer with further infantile jibes. Mr.Reay's behaviour
    calls for some comment - he uses every opportunity to
    goad, but when things turn against him as the direct result of
    his goading, he runs sobbing and screaming to the plod pod. Such
    behaviour is hypocritical and not the sort of example
    that should be set in public by someone who is
    a school teacher. I say that such a public display of childish
    behaviour by Mr.Reay renders him unsuitable to have any
    position, paid or voluntary, where he would be responsible
    for the training of young people.

    Cité Soleil, seems a most inappropriate name for such a place.

    Perhaps you could get the Yanks, who are responsible for most of
    the problems in that part of the world, to help?

    if you know anything about these devices you will know that
    they dont use 500v on the milliohm scale.
    they select an appropriate voltage depending on the user scale/selection.

    but going by your posting you dont.
    but you do now.

    i take it you dont know either!

    ahhhhhh..isnt it nice to see such behaviour on two newsgroups.


    strange how the dictionary-dot-com brigade havent picked you up
    on your spelling yet.


    i'm sure they will be along in a moment.
    even the less important one.
     
  15. OI, Beanie, put me back in your kill file immediately!
    I had worked out that the 500V was probably either for insulation tests
    or for connection to your private parts.

    (I believe FRANCES to be
    The University of Life is an excellent place provided, of course, that
    you have a life. That excuses YOU, Beanie.

    Do I need to? Have a look at Iraq.

  18. Sure I will take it! Can you ship carefully packed to Florida via parcel
    post? I will reimburse the shipping charges!

    The only way of selecting an "appropriate voltage" would
    be by resistive dropping. This is a non-electronic device,
    with accurate resistors fashioned from coils of wire.

    The meter movement is interesting - it has two separate coils,
    one to respond to voltage and the other to respond to current.
    there is no return spring on the needle!
