8 PC- maintenance, Error messages and Power-on
failure
8.1 Required hard disk space for data storage.
The CM files stored on the hard disk can vary from 6MB to 30MB. Therefore it is important
from time to time to check whether enough free space is present on the hard disk.
ChemoMetec recommends a minimum of 10G Bs free space on the hard disk.
It is recommended to make a periodic archiving of CM files to external storage. Those
archived CM files can then be removed from the hard disk of the PC.
The periodic archiving can be made on either the creation date of the CM file, or when the
free disk space is below a certain amount, or when the disk space used for CM files
exceeds a certain amount. Contact the local IT Administrator in order to get information
about procedures for external data storing.
A good example of the archiving procedure could be based upon:

CM files older than 3 months are archived

CM files uses more than 50GBs of disk space, archive the oldest CM files until less
than 20GB is used

When less than 10 GBs free space, archive the oldest CM files unti l less than 20GB
is used.
Refer to the NucleoView NC-200 User’s Guide for additional information.
8.2 Error messages
Under certain conditions the NucleoView NC-200 software will display error messages
during operation. Corrective actions can be found in the Help section of the NucleoView

If the NucleoCounter NC-200 cannot be turned on, please verify that the power supply is
connected to the NucleoCounter NC-200 and a working mains plug.
