Site
Calibration
When
the
CentriFlow®
Meter
is
sent
from
the
Factory
it
is
set
with
Default
values
for
the
Static
Calibration
and
the
Calibration
Voltage,
which
were
chosen
for
the
particular
material
being
measured
with
the
meter.
As
described
in
the
previous
Section,
the
Static
Calibration
is
an
adjustment
that
ranges
the
Transducer,
the
Measurement
Element
of
the
meter.
This
Setting
will
not
change
unless
the
Electronic
Full
Scale
is
changed.
The
Calibration
Voltage,
however,
is
the
adjustment
that
is
made
to
Calibrate
or
Site
Calibrate
the
Electronics
to
a
particular
application.
Although
the
Factory
setting
may
be
quite
accurate,
it
is
likely
due
to
differences
in
installation,
feed
systems,
and
material
being
measured,
that
an
adjustment
be
made
after
the
CentriFlow®
Meter
is
installed.
This
procedure
is
very
simple
and
will
require
a
means
of
capturing
material
that
is
run
through
the
meter
and
weighing
that
material.
Depending
on
the
Configuration
of
the
CentriFlow®
Meter,
either
Type
I
or
Type
II,
the
method
of
capturing
the
material
to
be
weighed
will
be
different.
For
a
Type
I
Configura
‐
tion
the
material
can
be
captured
after
it
leaves
the
Pan
Section
of
the
meter,
if
the
installation
allows,
or
at
some
other
point
in
the
flow
path
after
it
has
been
measured
by
the
CentriFlow®
Meter.
The
closer
the
capture
point
is
to
the
end
of
the
Pan
Section
of
the
meter
the
less
likely
that
there
will
be
loss
in
the
measurement
sample
and
therefore
less
likely
that
there
will
be
an
error
in
the
Calibration
of
the
Electronics.
It
is
important
not
to
come
in
con
‐
tact
with
the
Pan
Section
when
capturing
the
measurement
sample
so
that
the
Electronics
does
not
give
incorrect
results
from
measuring
the
contact.
Always
remember
to
fully
secure
the
door
back
to
the
enclosure
before
resuming
normal
flow
through
the
meter.
When
performing
the
Site
Calibration,
it
is
recommended
that
a
minimum
of
five
samples
be
taken
before
making
any
Adjustments
to
the
Electronics.
Also,
it
is
recommended
that
the
sample
run
be
a
minimum
of
10
seconds
long.
This
will
allow
a
reasonable
amount
of
material
to
be
run
through
the
CentriFlow®
Meter
ensuring
an
accurate
adjustment
to
the
Calibration.
The
procedure
is
explained
as
follows:
Step
1:
Make
sure
that
the
TOP.RUN
page
is
accessed
to
begin
the
procedure.
Press
the
Reset
Button
on
the
Lower
Left
to
reset
your
count
to
zero
before
running
product
through
the
meter.
Step
2:
Run
product
through
the
meter
for
a
designated
period
of
time,
collecting
the
material
in
some
manner
after
it
has
passed
through
the
meter.
