I tried your link and got a "server not found" error. Do you have another link for this site? It seems to be crucial for understanding your questions.

Amaranth;
thx for your help. MAINLY,i want to understand the basic theory of ＥＭＦ　ＭＥＴＥＲ　and　any measuring error or limitation？
could u mind teach me about this?

I can't teach you what I don't know myself. I'm sure there are others here who can, though. Good luck.

ANYWAY~THANK YOU~

Just got back from the UK and a wonderful dinner with Blacknad and lovely wife.

Checked the link at the top of the page and it is broken so I can not help. Can you find a newer link?
