Power Cables

Each instrument is equipped with a three-wire power cable. When connected to an
appropriate ac power receptacle, this cable grounds the instrument chassis. The type of
power cable shipped with each instrument depends on the country of destination.
See Figure 3 on page 6 for the part numbers of these power cables. Cables are available in
different lengths. Check with your nearest Agilent Technologies service center for
descriptions and part numbers of cables other than those described in Figure 3.
Refer to "Contacting Agilent" on page 74. for further information.
