I have an 887AB (s/n 2513) that I acquired a few months ago that has a new Null Detector board that I'm curious about. The board is a (factory installed) null detector board that uses a single opamp, a Burr-Brown OPA-111. I bought a manual for this instrument from Artek Manuals that covers the serial number of my instrument, but there's nothing in the manual about the new null detector board (887A-4022, p/n 812610). If anyone has any information (a schematic would be wonderful), I'd love to get a copy.
Thanks for any help Dave M _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/volt-nuts_lists.febo.com and follow the instructions there.
