This morning between 0830 and 0910 it recorded 14.2mm rain with a rainfall
rate of 365.8!!!
I was stood beside it for part of the time and there was no obvious reason
for it.
Everything else appears to be correct - any ideas anyone??

Gheckos occasionally take up residence in mine... though not since I
blocked off the access holes in the base. Never known a ghecko to be
quite so active though... spurious readings of 1.5mm or so are more
typical.

Might be worth checking for wildlife -- otherwise I'd suspect an
intermittent short circuit in the micro switch on the tipper, or
associated leads and circuitry. OTOH when we see rates like that in
the tropics it's usually because it's raining.

Perhaps the reed switch is getting past its best?

I had a problem like this with mine and it turned out to be a defective ISS
board. Mine somehow had gotten damp I think, because there were two places
on the board which had black corrosion seeping into the edge of the board.
Fortunately mine was under warranty. If yours is not the reed switch or
wild life then check the ISS board for signs of corrosion. Worth making
sure that the ISS board cover is properly seated with no gaps in the seal
and that both screws are done up tight.

Thanks to all for the replies.
Being completely non-technical I have no idea what they mean, but I'll
attempt tp check them out anyway.
