Thanks to a fellow list member I obtained a rev C2 DS1620 temperature sensor chip and replaced the rev E2 chip on my "flat line" Thunderbolt board. The board is now a "curvy line" board. So the difference is definitely a DS1620 chip difference and not a tbolt firmware difference.
I made several 24 hour holdover runs with the old chip. I am going to let the unit run for a week or so to let the filters learn the new chip and repeat the holdover runs. Hopefully something will pop out of the data, but I am not too hopeful. There was not a lot of consistency in the data from the first holdover runs. Any ideas of what to look for or how to analyze the data? _________________________________________________________________ Windows Live™: Keep your life in sync. http://windowslive.com/howitworks?ocid=TXT_TAGLM_WL_t1_allup_howitworks_022009 _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
