At least two of the
entered standard
concentrations are
identical. Correct
the standard
concentrations.

• See the error text.

 Enter the standard concentrations so

that the first standard receives the
lowest concentration and the other
standard concentrations form an
increasing sequence.

The measured
values are not
strictly
monotonous!

• Error when measuring a standard

series: The measured absorbance
values of the standard series are not
continuously increasing or
decreasing.

 Repeat the standard measurements or

delete the single, incorrectly
measured standard result.

The ID cannot be
set.

• Error when entering the sample ID.

Different causes are possible. For the
precise cause please see the
information in the help box.

 See information in the help box.

The dilution cannot
be set.

• Error when entering the dilution.

Different causes are possible. For the
precise cause please see the
information in the help box.

 See information in the help box.

Calculation not
possible because of
division by zero.
Absorbance result
or Formula "b"
parameter is zero.

• An absorbance result was divided by

a "zero" value during the evaluation
of a

Division type method (Dual

wavelength method group). This is
not mathematically permissible.

 Check the reagents and samples used

and repeat the measurement.

 Do not enter "zero" as a value for the

Formula

b parameter.

There is only one
measurement left to
be performed in
this series of
measurement.
The maximum
number of
measurements
within one series of
measurements has
been reached.

• The number of measurements in one

measuring series is limited to 99.

 Start a new series of measurement

after maximally 99 measurements.
