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.
• The power supply has two output ranges. This feature allows more voltage at a
lower current or more current at a lower voltage. The desired output range is
selected from the front panel or over the remote interfaces. The
8V or 20V for the
E3633A and
25V or 50V for the E3634A annunciator indicates the presently
selected range.
• When you press key (the Limit annunciator blinks), 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/20A* or 25V/7A** range and controlled
from the front panel, then the
CV and 8V* or 25V** 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 HP-IB interface, the
Adrs annunciator will turn on. See “Display Annunciators’ on page v for more
information.
