4.
The external plastic funnel surface should be cleaned with clean water and a
sponge; this will generally remove any green Verdi Gris should this have been
allowed to grow.
5.
Chemicals/detergents should not be used if the water is to be collected for later
analysis. Otherwise mild detergents can be used if required.
6.
The internal funnel tube that directs water to the tipping buckets may need
cleaning, use a pipe cleaner or small nylon bristle wire brush or similar part to
insert into the pipe to clean it
7.
Clean or replace the gauze filter into the filter tube and replace the top cap (see
spare part 1723-PK-114).
8.
Remove and clean any dirt from the tipping buckets, being careful not to tip the
bucket should the rain gauge still be logging.
9.
Check that the gauge is still level. It is possible for the gauge to become tilted as a
result of small ground movements, vandalism etc.
10. There will be times when for one reason or another the rain gauge will be not
logging or will be disconnected from the logger, during these times it is a good idea
to check the balance arm of the bucket for stiffness. The easiest way to do this in
the field is to try and balance the bucket in its centre position, it should be very
difficult if not impossible to achieve this, if the bucket balances easily then examine
the bucket closely for any dirt or wear on the pivot pin and bucket tubes. Any wear
will require the unit to be repaired/replaced.
