Basic Operating Procedures

Note

This manual does not attempt to address all of the functionality avail-
able with the BioWorks operating software for the Biomek 2000.
Rather, this section provides a number of tutorial examples designed
to illustrate the most important and commonly used features of the
system.

For complete information on BioWorks features and functions, refer
to the BioWorks Software Reference Manual.

Editing the BioWorks Demo Method

This section will guide you through the basics of editing by changing an initial
configuration and a transfer function using the Demo method.

To begin, double click on the

Edit

icon in the BioWorks program group. This displays

the Edit window, as shown on the next page.
