 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.
Invalid zoom interval! Error in the process results method
step in the Zoom mode.
Permissible zoom range for the
wavelength scale:
• Wavelength interval at least 10 nm
• Entries for wavelengths only within
the range programmed in the
parameters for the method.
Permissible zoom range for the
absorbance scale:
• Absorbance interval at least 0.02 A
• Upper and lower limit for
absorbance interval +3 A or –3 A
 Please observe the stated limits in
the zoom procedure.
