Overview
The following section provides 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
for the output2 front panel operation.
– When the power supply is in the remote operation mode, you can return to the
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
the front panel and remote operation modes will not result in a change in the
output parameters.
– When you press (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 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 . 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 you of error codes. For example, the power
supply is operating in the CV mode in the 8 V/3 A 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 the GPIB interface, the Adrs
annunciator will turn on. Refer to “Display annunciators” on page 43 for more
information.
– The display provides the present operating status of the power supply with
annunciators and also informs you of the error codes.
