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 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 5
for more information.
