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 several 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 6 for more information.
Throughout this chapter the key to be pressed is shown in the left margin.
