PREPARATION
The
role
the
FCD
is
to
check
whether
your
rain
gauge
is
providing
accurate
readings
when
a

volume
of
water
is
discharged
into
the
rain
gauge
collector.
Therefore,
prior
to
using

gauge
should
be
cleaned
and
maintained
as
follows:
1
‐
Remove
the
enclosure,
clean
the
funnel
and
filter
to
ensure
water
from

is
flowing
as
it
should
be
2
‐
Using
a
tooth
brush
and
methylated
spirit
clean
the
bucket
gently
from
any
sediment
that
is
adhered
to
the
internal
surfaces
of
the
bucket.
3
‐
Dismantle
the
syphon
and
clean
it
(refer
to
rain
gauge
manual
or
video

4
‐
Ensure
the
bucket
axle
is
tipping
freely.
5
‐
Ensure
the
rain
gauge
is
sitting
level
by
checking
the
bubble
level
on
the
base.
6
‐
Check
the
reed
switch
operation
on
the
rain
gauge
using
a
multi
meter.
7
‐
Avoid
performing
the
calibration
check
when
there
is
any
rainfall
or
strong
gust
of
wind.
