Hi all,I'm looking for info on a kelvin varley voltage divider. I tried Yahoo, Lycos and Google. They all return hits on it but nothing of any real use. I even tried to search for a book on No much luck either. We need a few of these at work and some company wants to charge us $500 a piece. They have 4 rotary switches (each from 0-9). I understand that the resistor ladder has a high tolerance but $500 ?! ouch!Could someone point me in the right direction to find some info on the subject please. Maybe that's why these things are so expensive, there is no info :-).Thanks

It's not only the super-precise resistors, but the high-quality low-resistance switches that make them expensive. You can find them on eBay for $50 to $500. For example, this top-of-the-line 7-digit Fluke 720A is at $393 with 4 bids and 80-minutes to go, Other less-precise models go for less money, such as 99 cents, No, those look the same, but are called ratio transformers. :-)-- Thanks, - Win

Did a new and better post in alt.binaries.e-books.technical about theory and use of a kelvin varley divider, hope you'll enjoy it. It was a lot of scanning.

filter kelvinvarley in that group

It'd be nice if you could learn to post in some standardized format ;-)
