Cumulus Support

Fine Offset WH3080. After one year no rain is registered. Everything else still works, including solar. The rain gauge seesaw can be tipped easily (no friction by spiders or rust), but no rain is registered.
I checked all cable connectors (removed/inserted several times to remove oxidants).

But now, where to start to find the problem. What might be the most likely problem. Any suggestions?

As you have probably seen it is just a simple reed switch.

Just put a meter accross the reed to look for a 'loop' when the magnet passes (the magnet hasn't fell off has it ?)

Hi,

If you don't have a meter, temporarily plug the Rain cable into the Wind socket. Rock the rain sensor several times and a few km/hr of wind should be shown on the Console within 48 seconds.

If you do have a meter, the transmitter should be putting out about 20 uA on one of the the Rain pins (relative to the other). Such a low currrent sometimes can be "shorted" by mositure in the cable/connector.

Reeds are available from CPC/Farnell, or maybe the complete sensor from Clas Ohlson (but Maplin in the UK is probably cheaper).

Cheers, Alan.

Thanks for the advice.

Magnet is still there.
I swapped the wind- and rain plugs. After that "rain" was detected, and -after rocking the rain sensor seesaw- no wind speed.
So it looks like the transmitter is OK, but the rain sensor is defective.

My next step: contact the supplier, because there is a 2 years warranty.

Solved.
