Safety
Warnings,
Cautions,
and Notes
Warnings, cautions, and notes are defined and formatted in this manual as shown
below.
WARNING—High Energy and High Voltage
Exercise caution when using and calibrating a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the power circuit and on
the output and sense connectors of a power supply with a rated output greater
than 40 V. Filter capacitors store potentially dangerous energy for some time after
power is removed.
!
CAUTION
Operate the power supply in an environment free of flammable gases or fumes.
To ensure that the power supply’s safety features are not compromised, use the
power supply as specified in this manual and do not substitute parts or make any
unauthorized modifications. Contact the service technician for service and repair
help. Repairs must be made by experienced service technicians only.
WARNING
Describes a potential hazard which could result in injury or death, or, a procedure
which, if not performed correctly, could result in injury or death.
!
CAUTION
Describes a procedure which, if not performed correctly, could result in damage
to data, equipment, or systems.
Note
Describes additional operating information which may affect the performance of the
equipment.

Section 1. Features and Specifications
Description
The internal GPIB interface card allows you to operate your power supply from a
computer controller via the IEEE-488 communications bus. See Figure 1.1, “Sample
Configuration using GPIB Interface”.
The GPIB interface allows complete remote programming of your power supply,
including status reporting, settings query, and interrupt generation with
user-designated fault conditions. Both the voltage and current output are precisely
programmed directly in volts and amps with 16-bit resolution. Additionally, the
built-in DVM and current shunt measure the actual power supply output and provide
you with 16-bit readback. The programming command set is easy-to-use and
includes software calibration commands. The interface card comes standard with
several protection features such as programmable over voltage protection, foldback,
load isolation signal, and soft limits.
