Getting
started
Verify
that
battery
has
been
charged.
Switch
on
Switch
on
the
Meter
and
allow
the
meter
to
cycle
through
its
start
up
procedure.
Part
of
the
start
up
procedure
is
to
show
how
many
readings
are
currently
stored
in
the
meter.
You
may
wish
to
download
and
erase
any
stored
readings
before
taking
new
measurements.
You
can
find
out
about
the
download
procedure
in
the
section.
The
Fatmeter
should
be
switched
on
for
five
minutes
before
taking
measurements,
in
order
to
allow
the
sensor
electronics
to
stabilise.
This
should
be
done
before
the
check
pad
test
is
done.
Check
pad
test
It
is
recommended
to
test
the
Fatmeter
against
its
check
pad
every
day.
The
Fatmeter
will
prompt
the
user
to
verify
the
meter
against
the
check
pad
shortly
after
start
up,
but
please
note
the
recommendation
to
allow
a
five
minute
warm
up
/
stabilisation
period
after
turning
the
meter
on.
The
check
pad
test
involves
continually
taking
readings
and
displaying
the
RESEARCH
‐
1
value
for
the
reading.
It
does
this
regardless
of
which
calibration
setting
has
been
selected.
You
will
see
something
like
the
following
on
the
display:
C h e c k P a d
Y 6 5 . 8 N
The
value
shown
will
change
according
to
what
is
being
measured.
Place
the
meter
firmly
on
the
check
pad
with
the
sensor
making
good
contact
on
the
pad’s
test
area,
then
verify
that
the
value
displayed
on
the
meter
is
within
the
range
shown
on
the
pad.
Repeat
this
on
the
other
side
of
the
pad.
If
the
values
on
the
meter
are
not
within
the
range
shown
on
the
pad,
re
‐
try
the
test
while
making
sure
that
the
meter
is
properly
positioned
and
not
at
an
angle.
Once
the
meter
has
been
verified
against
the
check
pad
press
either
of
the
buttons
to
continue.
You
can
proceed
to
take
measurements
on
your
daily
product
samples.
Failed
check
pad
test
If
the
Fatmeter
displays
values
that
are
not
within
the
tolerance
shown
on
the
check
pad
then
something
has
changed
from
the
last
test.
Possible
areas
for
error
include:
•
Inexperienced
operator
carrying
out
the
checks;
•
Sensor
not
properly
located
in
aperture,
thus
not
in
contact
with
the
pad.
If
the
checks
using
the
check
pad
have
been
carried
out
correctly
then
we
must
suspect
that
the
calibration
in
the
Fatmeter
has
somehow
changed.
There
are
three
options
at
this
point:
•
Carry
out
a
check
in
Iso
‐
Propanol
Solutions,
and
verify
that
the
fatmeter
results
agree
with
calibration
table
supplied
on
the
rear
of
your
calibration
certificate;
•
If
this
check
is
OK,
then
the
pad
itself
must
be
faulty.
A
faulty
check
pad
is,
however,
very
rare.
•
If
this
check
confirms
that
the
Fatmeter
has
drifted
out
of
calibration
then
please
contact
Distell
to
arrange
for
the
Fatmeter
to
be
returned
for
service
and
re
‐
calibration.
If
in
doubt,
please
contact
Distell
for
advice.
We
will
talk
you
through
the
check
procedure,
and
advise
accordingly.
