5. OPERATION OF CASY TT
5.1 General
The CASY Instrument is operated using 13 control keys. Operation is divided into three distinct ar-
eas, each of which reflects the spatial arrangement of the keys (see Figure 6).

Because up to 20 device settings can be permanently stored for each measuring capillary, parameter
setting in most cases is done by selecting an appropriate setup. Each time the CASY System is
switched on, the previously used setup and the previously used measuring capillary are loaded. All
other setups are readily available through the menu function. In addition, the measuring and output
parameters can be modified to match the actual measurement and do not have to be stored in one
of the setups.
5.2 Menu Control – MAIN MENU
All settings of the CASY System are selected with the MENU key. Pressing MENU displays the MAIN
MENU.
