Front-Panel Operation Overview
The following section describes an overview of the front-panel keys before
operating your power supply.
• 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 (
Local
) 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 key (the
Limit
annunciator flashes), the display of
the power supply goes to the limit mode and the present limit values 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 Limit annunciator turns off). In this mode,
the actual output voltage and current will be displayed.
• The output of the power supply can be enabled or disabled from the front
panel by pressing key. When the output is off, the
OFF
annunciator
turns on and the output is 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
power supply is operating in CV mode in the 8V/3A range and controlled
from the front panel, then the
CV
and
8V
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’’,
starting on page 5 for more information.
• The display provides the present operating status of the power supply with
annunciators and also informs the user of error codes.
