Restore Calibration Data
Each
unit
is
electronically
calibrated
at
the
factory.
The
calibration
values
are
entered
by
the
keyboard
and
stored
in
non-volatile
memory.
Do ABS Set Test 212!
Do Temp Set Test 210!
If
either
of
these
messages
are
printed
or
displayed,
it
indicates
that
the
calibration
values
have
been
lost.
These
messages
will
be
printed
each
time
that
you
turn
on
the
instrument,
select
a
mode,
or
recall
a
test.
The
instrument
will
continue
to
operate,
but
the
calibration
must
be
restored
to
ensure
the
accuracy
of
the
instrument.
Follow these steps to restore the electronic calibration:
1.
Shut off the instrument. Remove any tubes or cuvettes from the incubation block and
read
well.
Carefully
lift
up
the
instrument
and
locate
the
Calibration
Data
label
on
the
underside
of
the
unit.
There
are
three
values
recorded
there:
Absorbance,
Block
Temp,
and Cell Temp. Write down these numbers.
Set the power switch to ON (1).
If the date and time are incorrect, set the correct date and time. Press TIME then press
EDIT. Enter the date and time as prompted.
Press MENU, type in 210, and press ENTER. When the display shows “Block=",
enter the number that is recorded under the Block Temp heading on the calibration
label. For example “0.3” or “-0.2” and then press ENTER.
The display will prompt “Cell=”. Enter the data from the Cell Temp line of the calibra-
tion label.
Press MENU, type in 212, and press ENTER. When the display shows "Abs Factor="
enter the number from the Absorbance line of the calibration label. If the message
Adjust Out of Range is displayed, check your values and repeat this step.
Press MENU, type in 213, and press ENTER to get a report of the calibration data. The
block and cell temperature adjust will be printed along with the absorbance adjustment.
Make sure that these values are the same as those recorded on the calibration label.
