WS3600 rain value problem

Hi all, I have a very strange problem with my WS3600. In the night when the computer is turn off and start to rain, the station take an unreal values of rain. For example to night the station take 15 mm of rain, but neighbors station said no more 0.6 mm. This failure only happens when the computer is off, if the computer is on the rain values are normal.

Can anybody help me?

Thank’s

Do you use Fetch3600 when you restart the PC and WD to get the history data from the station from the night time?

So that when it loads in the data to WD you get strange high numbers for rain during the time it was turned off?

Yes, WD get unreal value of rain, but this values normaly are not the same unreal values that Ws-3600 console show.
