4. Conventional Operation: Menu System, Keypad, and Displays
NOTE: Figure 4-3 shows the instrument's Home Menu
structure. The information provided in the following two
manual sections explains what each function does and
shows how to access the function through the menu
system. The EVALuation MODE Function (located in
the EVAL Menu) determines which results-evaluating
submenu appears in the HOME Menu (these options
are listed in Figure 4-4). You'll also find operation-
manual section references that tell you where to turn
in this manual for more specific information on each
function.
The Home Menu System consists of several menus,
submenus, and functions.
• If not displayed, conventional mode is accessed
by pressing .
• Available menus are accessed via the Home Menu
(Figure 4-3).
• Each menu contains several submenus.
• Menus used for evaluating results (TCG, DAC, DGS,
dB REF, AWS, and JISDAC) are first selected by the
user (via the EVAL MODE function). The evaluation
menu selected then appears in the HOME Menu.
• Menus and submenus are selected by pressing
below the desired item.
• When a submenu is selected, the functions con-
tained in that submenu are listed in the Function Bar
down the left-hand side of the display screen.
• Functions are then selected by pressing the adja-
cent Function Key
• Turning the Function Knob, and in some cases con-
tinuing to press , will change the value shown in
the selected function's box. In some cases, pressing
and holding will set the function's value to zero.
Note that some functions, like RANGE, have both coarse
and fine adjustment modes. Coarse and fine modes are
selected by pressing
tion name, such as RANGE, appears in all capital letters,
turning the function knob will produce large changes in
the selected function's value. When the function name
appears in all lower-case letters, turning the function knob
will change the value by smaller amounts. Functions with
coarse-and-fine adjustment capabilities are noted with an
* in Figure 4-3.
NOTE: Figure 4-4 displays the structure of all menus
available for evaluating conventional data. Use the
EVAL MODE function, in the EVAL Menu, to choose the
feature used for evaluating results (TCG, DAC, DGS,
dB REF, AWS, or JISDAC). Once selected, the menu
corresponding to the EVAL MODE setting is directly
accessed through the HOME Menu.
