Manual Revisions

If changes have been made to your power supply since the publication of this manual, a yellow Manual Change
sheet may be supplied with the manual. It defines the differences between your power supply and the unit described
in this manual. The yellow change sheet may also contain information for correcting errors in the manual. Note that
because not all changes to the product require changes to the manual, there may be no update information required
for your power supply.

Firmware Revisions

You can obtain the firmware revision number by either reading the integrated circuit label, or query the dc power
supply using the GPIB *IDN?' query command (See Chapter 3, ROM Upgrade).

Electrostatic Discharge

CAUTION: The dc power supply has components that can be damaged by ESD (electrostatic discharge).
Failure to observe standard antistatic practices can result in serious degradation of performance,
even when an actual failure does not occur.
When working on the dc power supply, observe all standard, antistatic work practices. These include, but are not
limited to:
—
Working at a static-free station such as a table covered with static-dissipative laminate or with a conductive
table mat (Agilent P/N 9300-0797, or equivalent).
—
Using a conductive wrist strap, such as Agilent P/N 9300-0969 or 9300-0970.
—
Grounding all metal equipment at the station to a single common ground.
—
Connecting low-impedance test equipment to static-sensitive components only when those
components have power applied to them.
—
Removing power from the dc power supply before removing or installing printed circuit boards.
