Rules to navigate menus
Many functions and operations are configured from the front-panel menus. Use the following rules
to navigate through these configuration menus:
• A menu item is selected by placing the cursor on it and pressing the ENTER key. Cursor
position is denoted by the blinking menu item or option. The EDIT or keys control
cursor position.
• A displayed arrow on the bottom line indicates there are one or more additional items (or
messages) to select from. Use the appropriate cursor key to display them.
• A measurement or voltage bias source range is changed by selecting the channel and
function with one of the MSR1, MSR2, SRC1, or SRC2 keys, and then using the RANGE
or keys. Note that when the next higher or lower range is selected, the reading increases
or decreases by a decade (factor of 10).
A parameter value is keyed in by placing the cursor on the digit to be changed and using one of
the following methods:
• Use the EDIT or or the RANGE or keys to increment or decrement the digit.
• Use the number keys (0 through 9) to key in the value at the selected digit.
• Use the ± key to change source value polarity, regardless of cursor position.
NOTE You can clear a parameter value by placing the cursor on it and pressing the 0000
(MENU) key.
• Boolean selections (such as ON/OFF and HIGH/LOW) are toggled by placing the cursor on
the selection and pressing an EDIT or a RANGE or key.
