Well, I did the experiment.... I put the unit into holdover, spritzed the DS1620 temp sensor with cold spray, no immediate change in the DAC voltage was seen. Then about 10 seconds later the DAC reading shot up. After a minute or so, the temp reading was rapidly rising its way to normal and the DAC voltage was dropping, lagging by about 10 seconds. Looks like the temperature definitely sensor affects holdover compensation... ----------------- Probably can't argue with that then:-) Another thought I had earlier, is it possible perhaps that Trimble were running out of space for a firmware upgrade and cut back on the complexity of this routine having decided that precision of ambient temperature measurement was sufficiently of a "secondary" nature not to warrant the extra code they'd used when more space was available? regards Nigel GM8PZR _______________________________________________ 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.
