Both the Agilent 34420A & Keithley 2182A nV meters use Lemo connectors and their docs suggest DeoxIT (this is when talking about connectors). e.g. from the Keithley doc: "Make sure that all connections are clean and free of oxidation to avoid thermal EMFs that could affect measurement accuracy. Clean oxidation from connector terminals with DeoxIT cleaning solution."

FYI the contacts of the Lemo connectors look like naked copper to me. _______________________________________________ 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.
