The Nova5000 is connected directly to your PC and used as a standalone data logger instead of the MultiLogPRO. Using the Nova5000 in this way lets you benefit from the full range of MultiLab PC functionality, not all of which is available in the lighter MultiLab CE version.
Page 112 9. The Download and Setup Wizard icons in the MultiLab main toolbar will change to indicate that the PC is communicating with the Nova5000, rather than with MultiLogPRO: 10. The Nova5000 is now ready for full control by the MultiLab for PC.
