5.2 MANUAL MODE
There are three modes of operation: Manual mode, Program mode, and Run mode. Manual mode is used
to prepare the system to run a programmed method, or to perform tasks that do not require a programmed
method, such as simple pumping tasks. When you first turn on the system, the Manual mode’s Pump
Control screen is displayed so that you can purge the system, calibrate the pump, and select the buffers for
your application. To select other Manual mode functions, use the Instrument keys on the front panel. The
top line of each screen in Manual mode displays the following:
• Method name: The name of the currently loaded method. Changing the method name is done in
Program mode.
• Mode of operation: The mode is also indicated by the key’s LED being lit.
