When operated over the remote interface, the power supply can be both a listener and
a talker. Using an external controller, you can instruct the power supply to set the
output and to send the status data back over the GPIB or
RS-232. Capabilities include the following features:
• Voltage and current programming
• Voltage and current readback
• Present and stored status hardback
• Programming syntax error detection
• Complete self-test
The front-panel VFD (Vacuum-Fluorescent Display) includes:
• Displaying actual values of output voltage and current (meter mode)
• Or displaying the limit values of voltage and current (limit mode)
• Checking the operating status from the annunciators
• Checking the type of error from the error codes (messages)
Front panel binding posts are available to connect load wires for bench operation.
Connections to the power supply’s output and to chassis ground are made to the rear
output terminals.
W a r n i n g Floating the power supply output more than ±60 Vdc from the chassis presents an
electric shock hazard to the operator. Do not float the outputs more than ±60 Vdc
when uninsulated sense wires are used to connect the (+) output to the (+) sense and
the (-) output to the (-) sense terminals on the back of the unit.
