2.3.4 Navigating menus
There are basically two types of menu structures; the Main
Menu and the Configure menus. The Main Menu accesses
items for which there are no dedicated keys, and Configure
menus are used to configure measurement functions and oth-
er instrument operations.
Use the following rules to navigate through the menu struc-
ture:
1. The top level of the Main Menu is accessed by pressing
the MENU key. A Configuration menu is accessed by
pressing CONFIG and then the desired function (DCV,
ACV, etc.) or operation (TRIG, STORE, etc.).
2. A menu item is selected by placing the cursor on it and
pressing ENTER. Cursor position is denoted by the
blinking menu item or parameter. The cursor keys (
and ) control cursor position.
3. A displayed arrow ( and ) on the bottom line indi-
cates that there are one or more additional items (mes-
sages) to select from. Use the appropriate cursor key to
display them.
4. A numeric parameter is keyed in by placing the cursor
on the digit to be changed and using the RANGE ▲ or
▼ key to increment or decrement the digit.
5. A change is only executed when ENTER is pressed.
Entering an invalid parameter generates an error and the
entry is ignored.
6. The EXIT key is used to back out of the menu structure.
Any change that is not entered is cancelled when EXIT
is pressed. The EXIT key has additional actions and are
summarized in Table 2-5.
2.4 Functions
To minimize the need to reprogram setup conditions every
time you switch from one function to another, each function
“remembers” its own unique setup configuration. Setup con-
figuration parameters that are remembered include:
• Range
• Relative
• Integration time
• Filtering
• Display resolution
• Multiple displays
To access the configuration menus for the measurement
functions, press the CONFIG key and then a function key
(DCV, ACV, DCI, ACI, Ω 2, Ω 4, FREQ, TEMP). Rules for
navigating the menu structures are covered in paragraph
2.3.4.
2.4.1 DC and AC voltage
The Model 2002 can make DCV measurements from 1nV to
1100V and ACV measurements from 10nV to 775V. The
basic measurement procedures for DCV and ACV are con-
tained in the Getting Started manual.
Voltage configuration
The following information explains the various configura-
tion options for DC and AC voltage measurements. The con-
figuration menus are summarized in Tables 2-6 and 2-7. The
menus are accessed by pressing CONFIG and then DCV or
ACV. Paragraph 2.3.5 summarizes the rules for navigating
through menus.
Note that a function does not have to be selected in order to
be configured. When the function is selected, it will assume
the programmed status.
