Front-Panel Operation Overview
The following section describes an overview of the front-panel keys before operating

• The power supply is shipped from the factory configured in the front-panel
operation mode. At power-on, the power supply is automatically set to operate in

used. When the power supply is in remote operation mode, you can return to front-
panel operation mode at any time by pressing the
previously send the front-panel lockout command. A change between front-panel
and remote operation modes will not result in a change in the output parameters.
• The power supply has two output ranges. This feature allows more voltage at a
lower current or more current at a lower voltage. The desired output range is
selected from the front panel or over the remote interfaces. The
