I noticed a previous poster had noted that their EnviR lost time. I've got the opposite problem where mine is getting ahead of itself. Is there any way to prevent this or push a time update via the data cable? |

Hello I am facing a similar problem........I had bought one 2 weeks ago and it seems to gain 15 minutes every week. I think i am going to return it. I also checked out the earlier post on EnviR and there was no proper solution provided. But if there is anything you come across....let me know. |

Mine is also GAINING time. Maybe 5 minutes per month. We need a firmware update that will adjust the time if the unit is connected to a computer. Can't be that difficult to do. |

Looking at Jack Kelly's pictures, it seems that there is an external crystal that's used for some timing information. I don't know if it's used for the clock or not. The PIC that's used does have a real time clock (RTC) peripheral on-board, but I wonder if it's actually used, given the comment about the clock stopping when a history download is occurring. If the RTC is used, then it does have the ability to be adjusted in software. Mine doesn't keep good time at all - it drifts enough that it loses around 20 minutes a month. |
