Figure 4-1: Shuttle Knob
Two different style keyboards are available for the Lx/Ls Series. The Ls Series comes standard
with a dual shuttle knob keypad. All data entry is made by using these shuttle knobs. The Lx
Series comes standard (as of Q1-2006) with a numeric keypad and single shuttle. Data entry can
be done either through the 0-9 numeric keypad or using the single shuttle.
The shuttle knob(s) are/is located to the right of the LCD screen and are used to change setup
parameters. Note that it cannot be used to move the cursor position between menu fields. Use
the UP and DOWN arrow keys for this.
The shuttle knob can operate in one of two distinct modes of operation:
MODE DESCRIPTION
IMMEDIATE mode Any time the ENTER key is pressed, the Lx/Ls Series returns to
its normal mode of operation. In this mode, changes made with
the shuttle knob will take immediate effect. The IMMEDIATE
mode is useful for slewing output values such as voltage and
frequency and observing the effect on the load.
SET mode When the Set key is pressed again while the PROGRAM screen
is already displayed, changes made with the shuttle to any
output parameter will not take effect until the ENTER key is
pressed. In this mode, any changes made to a setup menu will
have a blinking cursor to indicate the pending change condition.
This mode allows changes to be made to all output parameters
and executing them all at once by pressing the ENTER key.
