Quick Start
One of the first things you will want to do with your power supply is to become
acquainted with its front panel. W ritten 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 fac tory configured in the front-panel
operation m ode. A t power-on, the power supply is autom aticall y 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 re mote interface s. 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 flashes), the display of
the power supply goes to the
limit
mode and the present limit values wil l
be displayed. In thi s 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
displ ay to the
meter
m ode (the
Limit
annunciator turns off). In this mode,
the actual output voltage and current wi ll 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 exam ple, 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 GPIB interface, the
Adrs
annunciator will turn on. See “

Annunciators
