5.3.01 Main Display

Figure 5-2, Main Display - Single Reference Mode
The Main Display always appears on power-up and is similar to that shown in
figure 5-2 above. It is divided into two sections by a single vertical line. Five
instrument controls appear on the left-hand side, of which the topmost one, AC Gain,
is always displayed, whereas the other four are user-specified using the Control
Selection menu, discussed later in section 5.3.02. On the right-hand side, four
instrument outputs are displayed in one of the three following formats:-
a) Two large numeric and two bar-graphs
b) Four bar-graphs
c) Four large numeric displays
The display mode is selected via the center key pair of the five keys to the
right of the screen, with each key press changing the mode. In any given display
mode, the choice of the output that will actually be shown in each of the four
positions is made using the corresponding right-hand keys. In single reference
mode, there are thirteen possible outputs to choose from for each numeric display,
with nine choices for the bar-graph displays, as listed in table 5-1.
