That is pretty normal, it's very hard to control temperatures so precisely that you don't get a few hundred nanovolts of seebeck voltage. If you touch the short with your finger, you will change the temperature enough that it registers clearly. I mount the short, then hang a piece of cloth over the terminals and wait about 15-30 minutes before I run ACAL 0 -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
