Static
Calibration
(Static
Cal.)
Static
Calibration
sets
the
Range
of
the
Transducer
in
the
CentriFlow
Meter.
This
allows
the
meter
to
be
versatile
in
a
way
such
that
it
can
be
ranged
up,
known
as
Extended
Static
Calibra
‐
tion,
or
it
can
be
ranged
down,
known
as
Reduced
Static
Calibration.
The
Static
Calibration
is
a
Factory
Setting
and
should
not
need
to
be
changed
while
the
meter
is
in
service,
unless
the
Transducer
has
been
replaced.
Setting
or
checking
the
Static
Calibration
consists
of
two
steps
–
Zero
and
Static
Calibration.
Note
that
readings
are
measured
using
two
different
units
‐
%PV
and
%
Volts.
The
difference
between
the
two
scales
is
the
Dynamic
CAL
multiplier.
The
nomi
‐
nal
value
is
five
(5),
this
value
equates
to
multiplying
by
one.
Before
beginning
the
calibrations,
make
sure
that
there
is
no
product
on
the
Pan
or
around
the
Pan
Arms.
