Now I've cheated here a bit ;-) You'll like this, not a lot!

Because I couldn't *raise the screws to allow more frequent tips ~ in
effect less fluid in each tip ~ I thought I'd compensate for this by
putting a small and equal amount of 'blue-tac' in the inside/eachside of
the tipper, thus the 'blue-tac' compensates for what would have been
water, so now less water is required to tip. Obviously the weight is
different but as long as through testing the desired result is acheived,
I can't see it being any less accurate than just having raised the
screws and the reed switch functioning.
*From reading on this thread it seems important to get a good tip, as it
were, and I am concerned that the magnet/reed switch is less effective
with the screws up and less of a tip so even changing the reed switch
won't guarentee it working.

A bit 'Heath-Robinson', but I'll carry on making comparisons.

Yee-Ha

Hi, Keith,

Just a thought. My Davis gauge is a very old one - Weather Wizard 111
and I'm almost sure the buckets are imperial measure (0.25mm tip) as
opposed to metric (0.2mm tip). So when the set-up is for metric I only
get 20/25th (80%) of the rainfall. To allow for this my machine is set
for 0.01in (imperial) on the accessories and mm (metric) on the units.
My tips are thus in 0.25mm stages.
09Z-09Z today was 19.9mm in the Met O gauge and 78 tips on the Davis.
The 78 tips would give 15.6mm set at 0.2mm tips and 19.5mm set at
0.25mm

Do you think this could be applicable to your instrument?
HTH.
