8 Troubleshooting - Error messages
39
The error appears if the concentration of stained nuclei inside
the cassette chamber is far too high, e.g. when the sample is
insufficiently diluted. The message can also appear if the lid
is not closed, which may cause ambient light to interfere with
the analysis. Press any key to continue.
8.5 Sensor error
The black dots, which are printed on the cassettes are read by
sensors inside the NucleoCounter each time an analysis is run.
The dots code for the volume of lyzate mixture in the cassette
chamber. If one or more of the sensors has a faulty operation
an error message will be displayed, see Figure 31.
Sensor error
Refer to manual
Press any key
Figure 31. This error message is displayed if one of the
sensors, which read the black dots on the cassettes,
causes error.
If the error message is displayed analyses can still be made
but the accuracy of the results cannot be guaranteed since the
volume of the measurement chamber may not be read correctly.
8.6 Power-on failure
If the NucleoCounter cannot be turned on, please verify that
the power supply is connected to the NucleoCounter and a
working power plug.
If the NucleoCounter still does not turn on, inspect and/or
replace the fuses as described below.
The fuse holder is located just above the NucleoCounter´s power
plug, see Figure 32
