[Test-Equipment] Megger Biddle 63220 Earth Tester

[John D. Farr]

Dave:

I have a scanned copy of "A Manual on Ground Resistance Testing for users of 
Megger Ground testers" by the James jG. Biddle Co. It is an 11 meg pdf 
document that will probably have to be broke up in chunks to get it to you 
via email. Let me know if you want it.

Please know that I need a manual on this instrument also. Mine has a burned 
resistor of unknown value. I'd like to test it with a network of resistors 
once it's repaired. The manual should help me with this. I'd be glad to pay 
copying costs and postage if you score the manual.

thanks, John
