Doh. That 14+3 actually equates to ~=3 ppm ~= 0.3 uV (since reading is essentially zero), but there's also temperature, which contributes > 0.115 / C. _______________________________________________ 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.
