Quick Start
One of the first things you will want to do with your power supply is to become
acquainted with its front panel. Written 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 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.
– When you press the “Display Limit” key (the Lmt annunciator blinks), the
display of the power supply goes to the limit mode and the present limit
values of the selected supply will be displayed. In this mode, you can also
observe the change of the limit values when adjusting the knob. If you
press the “Display Limit” key again or let the display time-out after several
seconds, the power supply will return the display to the meter mode (the
Lmt annunciator turns off). In this mode, the actual output voltage and
current will be displayed.
– All outputs of the power supply can be enabled or disabled from the front
panel using the “Output On/Off” key. When the output of the power supply
is off, the OFF annunciator turns on and the three outputs are 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 +6V
supply is operating in CV mode and controlled from the front panel, then the CV
and +6V 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
Display Annunciators for more information.
