NO
CALCmATION
Results
are
sent as absorbance$ to built-in printer or via the inte~aface.
The measured absorbance values are compared with two limit values
dsfined by the user.
If
the result
is
lower than the lower
firnit,
a
negative sign
(-)
is sent.
If
the result is between the two limit values,
0
is sent.
If
the nsult is higher than the upper limit, positive sign
(+)
is
sent.
The measurement parameters, calculation pawmeters an
results in
-1011-
matrix are sent to the build-in printer or via the
interface.
Parameters:
Low limit value (LOW

Range value defined by the user
is
divided into ten equal segments
Segments are numhred from
0
to
9.
The measured absorbance value
is
represented by one of those numbers depending on which segment
it lies in. The measurement parameters, calculation parameters and
matrix where the results are shown by segment numbers
(0
...
9)
are
sent to the built-in printer
or
via the interface.
Parameters: Range value

If
an absorbance range
