Agilent Technologies 6814B Pacemaker User Manual


 
Introduction
8
Note 1) If the serial prefix of your unit is higher than that shown in the title page then the unit was made after
the publication of this manual and may have hardware and/or firmware differences not covered in this
manual. If they are significant to the operation and/or servicing of the AC Power Source, those differences
are documented in one or more Manual Change sheets included with this manual.
2) If the serial prefix on the unit; is lower than that shown on the title page, then the unit was made before
the publication of this manual and can be different from that described here. Such differences are covered
in “Appendix A - Manual Backdating Changes” in the User’s Manual.
Firmware Revisions
You can obtain the firmware revision number by either reading the integrated circuit label, or query the AC Power Source;
using the GPIB *IDN query command (see "Chapter 3 -Troubleshooting" ).
Electrostatic Discharge
The 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 AC Power Source; 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 AC Power Source before removing or installing printed circuit boards .
