Quick Start

One of the first things you will want to do with your power supply is to become

acquainted with its front panel. Written procedures in this chapter prepare the

power supply for use and familiarize you with most front-panel operations.

• 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 the front-panel operation mode. When in this mode, the front-

panel keys can be used. When the power supply is in remote operation mode,

you can return to front-panel operation mode at any time by pressing the

key if you did not 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.

• When you press the key (the Lmt annunciator blinks), the

display of the power supply goes to the limit mode and the present limit

values of the selected supply will be displayed. In this mode, you can also

observe the change of the limit values when adjusting the knob. If you press

the key again or let the display time-out after sever al

seconds, the power supply will return the display to the meter mode (the

Lmt annunciator turns off). In this mode, the actual output voltage and

current will be displayed.

• All outputs of the power supply can be enabled or disabled from the front

panel using the key. When the output of the power supply

is off, the OFF annunciator turns on and the three outputs are disabled.

• The display provides the present operating status of the power supply with

annunciators and also informs the user of error codes. For example, the +6V

supply is operating in CV mode and controlled from the front panel, then

the CV and +6V annunciators will turn on. If, however, the power supply is

remotely controlled, the Rmt annunciator will also turn on, and when the

power supply is being addressed over GPIB interface, the Adrs annunciator

will turn on. see "Display Annunciators" on page 5 for more information.

Throughout this chapter the key to be pressed is shown in the left margin.
