Sensor lost contact ?

I noticed when my fine offset had a 'sensor lost contact' the measured values stay the same , I'm not sue about this because this was the first time the problem was for about 15 minutes. Assuming the data cannot be send to the console the data are lost in the mentioned period because the transmittor has no memory is my conclusion right ?

That's right; any outside data is lost while the transmitter can't talk to the console. The partial exception is the rainfall total, which will be recorded all at once when contact is re-established.

Thanks for confirming, I only can't understand how cumulus can 'know' how much rain was fallen in the non-communicating time is there an explanation ?

Because all Cumulus ever gets from the station is a 'total rain counter', which keeps incrementing in the transmitter. So in that sense, the transmitter does have a memory, but only for the current value of the total rain counter.
