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. 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 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 22 for more information.
