Working with the Control Module
Working with Methods
The left arrow key can be used as backspace, the right arrow key is used to move to
the next character position.
Protecting a Method
To protect the current method.
The method is now protected against inadvertent changes. Any changes to the
method will not be accepted until the method is unprotected, by saving it again
without protection. For further protection remove the Control Module from the
Instrument and store it in a secure place.
Any unauthorized method or instrument changes can be traced by the system
logbook.
Saving a Method
Although it may seem that methods are stored within the control module, in fact all
data concerning methods is stored in the modules themselves. The control module
generates a list of all available methods that can be loaded.
The number of methods that can be stored depends on the number of timetable and
injector program lines included. In general about 15 methods may be stored which
contain about 50 timetable lines per module. With differing method contents the
actual amount of methods to be stored may change significantly.
Use PC cards in order to store infinite numbers of methods for future use or
exchange between LC instruments (see "Transferring Methods Between LC
Systems" on page 42).
