How do I prevent data gaps when clearing device memory?

[jferristx]

I have my own station and one at work. (A WS-1090 and a WS-2080). I run only Cumulus. Currently, about once a month, I close Cumulus, Open EasyWeather, export all data for a given time period to a .csv, clear memory, close EasyWeather and restart Cumulus.

Obviously, no matter how fast I do this, I get small but really really annoying gaps in the data. Can someone tell me if I'm doing this wrong, if there is a better way to do this, or if that's just how it works. I'd like a continuous record because I'm a weather geek. (My daughter is meteorologist with the Air Force) Who knows, at some point, I know I will need that one small period of data to find the solution to prevent a zombie invasion.

Thanks

Why do you clear (station) memory ?

It's a cyclic store. (new overwrites old when full)

As was pointed out the logging is cyclic, but if you are using MS Excel or other spreadsheet software to read the CSV file, you could just import the monthly cumulus text files into the spreadsheet using the import data functionality. I do this when looking for the odd data anomaly I get with my WS2350.

Hi,

As already said it's not necessary to clear the memory, but if you want to reset the "memory clock face" for example to remind you when the next download will be necessary then I think you just need to change your procedure slightly.

I close Cumulus, Open EasyWeather, export all data for a given time period to a .csv, clear memory, close EasyWeather and restart Cumulus.

Presumably the gap is in the Cumulus data? Use the procedure above but don't clear the memory. Restart Cumulus to download any data missed during the EW download. Now, you might be able to clear the memory directly on the logger (touchscreen) but I'm not sure if Cumulus will be happy with this (I don't want to clear the data in my station to try it). But if not, then close Cumulus again (to be absolutely sure you don't miss any data you could wait until just after a dataset is logged) then reset the memory (and restart Cumulus again, if required).

If the logger memory only needs reading every month, then presumably your logging interval is at least 10 or 15 minutes so you should have ample time.

Cheers, Alan.

Geez, I've spent too many hours as a computer programmer. Never considered the "don't clear the memory" thing. Grew up with Windows 3.11....you ALWAYS cleared the memory (also known as a reboot). Ok, got it, just regularly roll the data off and I won't have any gaps, so long as I do it on a regular interval with time periods short enough to prevent it rolling off the data. Is that last statement correct? I was using the memory "clock" as a reminder as to when to do it.

Many thanks for the help
