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. When in this mode, the front-panel keys can be used. At power-
on, the power supply is automatically set to operate in the front-panel operation
mode and the output1 is selected for front panel operation. Press
key for
the output2 front panel operation.
• 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 7 for more information.
• The display provides the present operating status of the power supply with
annunciators and also informs the user of error codes.
