Megger/Wheatstone Bridge to a good home?

Jan 28, 2005 91 Replies

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!


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?

They are actually used for testing electrical insulation (you know by electricians!!). For accurate resitance measurements you'd be better off spending a fiver on a brand new DVM from Maplin (they are in the bins near the tills). Why do you want to measure accurate resistance anyway? The tolerances of resisters used in electronics are as wide as barn doors.

Still stick it on ebay and you might get for a quid for it.

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 > > I am opposed to organised charities which are a means

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)

You See, Believe and say lots of things. But get this! - No-one gives a F**k.

Have a nice day!

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?

And go round youre house you weird prick to collect ? sure thing

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.

I mustn be in Bean's kill file. He never replys to me.

Am I right in thinking, you have had to resort to buying friends?

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. ...(_!_)...

Perhaps you could elaborate on your most asinine statement?

Do I need to? Have a look at Iraq.
