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.
