Parameters are grouped in menus, selectable using menu keys. To select the
output channel parameters press the letter key corresponding to the desired
channel. To select second level menus press the

key and then the key
corresponding to the desired function. To select advanced channel menus press

Selecting Menu Items
Within a menu, the blinking cursor indicates the current menu item for editing.
The

Numeric Input Mode
When the current item is numeric, the system enters the Numeric Input Mode. In
this mode data may be edited in one of three ways. Using the arrow keypad, the
left (
LEFT)
and right (
RIGHT)
arrow keys are used to select a digit to edit. The
selected digit blinks to identify itself as the active digit. The
UP
and
DOWN
arrow
keys are then used to increment or decrement this digit. Alternately, after using
the
LEFT
and
RIGHT
arrow keys to select an active digit, the adjustment knob
may be used to increment and decrement this digit. The adjustment knob
features speed de-pendent resolution. Slow rotation will increment or decrement
the active digit by one. As you increase the speed of rotation, the parameter will
be 10 to 1000 times faster depending on the speed.
An additional entry mode is using the numeric keypad. Enter the number,
including decimal point using the numeric keypad. Complete the number using
the
ENTER
key. To clear number entry and/or start over press the clear key
(
CLR
). Pressing the
CLR
key a second time will exit the numeric keypad mode
and restore the original number.
The last entry mode is a modified form of scientific notation. The FUNC button
