Tony & TokKiwi. Thanks for your replies, I have tried both suggestions but am still without a reading, I guess I have a faulty rain guage, it has had a pretty rough life and isn’t a patch on my Davis gear.http://www.jsmith.id.au It’s a pity as I was hoping to put it in a sale that our local radio group are having but without the rain guage and anemometer I doubt if anyone will be interested. Regards John
