8.3 Actuator error messages
The actuator moves the piston down into the barrel of the cassette. Two different
actuator error messages can be displayed. These error messages are shown in Figure 30.
The same action is to be taken if either of the error messages appears.

First, examine if the cassette has been inserted properly. If not, insert the cassette once
more and attempt the analysis again. If the cassette was inserted properly turn the
NucleoCounter off and on a few times. If the actuator moves during start-up it is likely
that the error has been corrected.
8.4 Sample could not be analyzed
When the NucleoCounter cannot determine the concentration of cells during analysis the
error message in Figure 31 is displayed.

Figure Figure Figure Figure 31 31 31 31.... This error message is displayed when the concentration of cells in the
cassette cannot be determined
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.
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 32.
