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.

Device
configuration was
changed from …
to … .

• A BioSpectrometer kinetics is not

detected as the kinetic variant but as a
BioSpectrometer basic. The kinetic
methods are therefore not displayed.

 Switch the device off and back on

again. If the error occurs again:
Contact Technical Service.

The temperature
control system is
faulty. Please
program the
method without
temperature control
or cancel the
method.

• The temperature control of the device

is faulty.

 Contact Eppendorf Service. Until the

temperature control has been
repaired only use methods for which
no temperature control has been
programmed.

The ambient
temperature is too
high.

For kinetic methods with temperature
control:

• The ambient temperature measured

by the device is above the specified
range.

 Make sure that the ambient

temperature is within the range
specified for the operation of the
device.

Linear regression
could not be
applied to all
measurements.

• For kinetic methods, the time frame

for evaluation with linear regression
was changed in the

process results

method step, and the change should
be extended to all measuring results.
The required number of measuring
points, however, was not available for
at least one sample result.

 Only change the time frame for

evaluation with linear regression in
the

process results method step for

samples with sufficient measuring
points.
