Symptom:
Reported data values are lower than expected.
Solution:
1.
Ensure
that
the
filter
is
clean
and
allows
water
to
flow
through
it.
2.
Check
that
the
tipping
mechanism
can
move
freely.
3.
Use
a
voltmeter
on
the
switch
to
verify
the
switch
is
activated
as
expected
while
transitioning
from
one
side
to
the
other.
While
the
tipping
mechanism
is
in
its
resting
positions,
the
volt
meter
should
read
3
to
5
V.
When
at
the
mid-
point
as
it
transitions
from
one
side
to
the
other
side,
the
volt
meter
should
read
0
V.
4.
Ensure
that
the
RainVUE-series
is
level.
The
RainVUE
10
has
a
bubble
level
next
to
a
level
l
ing
foot.
On
the
RainVUE
20,
the
funnel
needs
to
be
removed
to
view
the
bubble
level.
5.
Check
the
wires
and
connections
between
the
switch
and
the
interface
are
secure.
6.
Verify
no
obstacles
are
preventing
rain
from
entering
the
funnel.
Symptom:
Reported data values are higher than expected.
Solution:
1.
Verify
the
tipping
mechanism
is
not
stuck
near
the
cent
re
of
its
movement
from
one
side
to
the
other.
2.
Verify
the
correct
Tipping
Volume
Option
is
in
use.
Check
the
label
inside
the
RainVUE-
series.
3.
Verify
that
the
wires
and
connections
between
the
switch
and
the
interface
are
secure.
4.
Verify
that
the
RainVUE-series
is
not
under
a
structure
that
will
drip
into
the
it.
