Hello Hugh. I'm afraid that your instrument is telling porkies. Make sure
all your connections are sound, and the battery, if it uses one, is good. If
you use a radio link, check the receiver unit too. RH below 20% is quite
rare. My lowest value in the past 17 years is 13% in May 2013. The average
lowest per month ranges from 53% in December to 26% in April.


Bernard, Thanks so much for your help and advice. That's exactly what
this group does best, helping an amateur.
