Hi all, I have a PCE-FWS20 produced by Fine Offset Electronics Co. LTD (Honk Kong), also known as:
Fine Offset WH1080/WH1081,
Watson W-8681/WX-2008,

I have a question:
almost every day the station measures 0.3 mm rainfall, probably caused by "moisture" in the rain gauge
example:
Today
Rainfall max. 0,3 mm at 08.06
Yesterday
Rainfall max. 0,3 mm at 08.08
Max hourly rainfall 0,3 mm at 05.50
Yesterday
Max hourly rainfall 0,3 mm at 05.52
In an old post I noticed that the station, every day at dawn measured 0,3 mm of rain, I thought it was moisture but I was wrong; It is related to solar panel, becuase if it is not sunny the rain is measured later then dawn.
So I connected directly rain meter to thermo-igro-transmitter, bypassing solar panel -> no rain at dawn or later is measured;
probably when the solar panel starts working 0,3 mm of rain is measured;
moreover:
1)when the rain meter is directly connected to thermo-igro-transmitter If i pour some water in rain meter, the water is measured
2)when the rain meter is connected to solar panel If i pour some water in rain meter, the water is NOT measured
All cable has been already tested and seems OK
The pole doesn't vibrate: it is strongly fixed to concrete wall
Thank You
