reasons of clarity, and do not necessarily reflect the actual colors used on the instrument display.
5.1 Data entry
5.1.1 Function keys
The display panel of the 9245 has 5 function keys (illustrated below) to allow menu option
selection, field selection, and data entry options.
• The Esc key cancels data input or goes back to the previous screen.
• The Enter key validates the input and goes on to the next step.
• The Up Arrow keys select the option displayed immediately above them on the screen.
When a screen requiring data entry is displayed, the first editable field is always highlighted (as
illustrated left in
Figure 13 below). To select other fields on the screen, scroll through them by
pressing the Up Arrow function key under the Select option. As each field is selected, the data
element available for update is highlighted.
The same is also true when a menu is displayed (as illustrated right in Figure 13 above). In this
case, the first available option is always highlighted. Scroll to the required option by pressing the
Up Arrow
function key under the Select option.
Data entry is effected in a variety of ways depending upon the characteristics of the data field
being accessed. The following examples show the different ways of entering data when
required.
