Blank
measurement: An
intensity on a pixel
that influences the
main, auxiliary or
scan wavelength is
too low. • The absorbance of the blank solution
used for the blank measurement is too
high.
• Incorrect or turbid blank solution.
 Check the blank solution and
remeasure the blank if required.
The entered name
is not valid. • Error when entering the name.
Different causes are possible. For the

A method (or
folder, protein, unit)
with this name
already exists. • The name under which the method
was saved has already been used for a
different method in the same folder.
• The message also appears after
edition names already given to a
folder or to a protein or a
concentration unit (under
General
Method Parameter).
 Assign a different name.
The following
parameter values
are not defined in
General Method
Parameter: • When opening a method with
parameters which access General
Method Parameter, the system
determined that at least one
parameter (protein, unit) does not
exist there anymore, so probably has
been deleted.
 Select a different parameter from the
existing list. If necessary, program a
new list entry in
General Method
Parameter in order to be able to use it
when programming a method.
The value of the

The entered
standard
concentrations are
not monotonically
increasing resp.
monotonically
falling. Correct the
standard
concentrations. • See the error text.  Enter the standard concentrations so
that the first standard receives the
