b. Perform Steps (b) through (e) of Paragraph
2-22.
2-25 CONNECTIONS FOR 50Hz OPERATION
2-26 For operation from a 50Hz ac input, R82
must be replaced with a 240 Ω, ±5%, ½ watt resistor
as specified under Option 005 in Table 6-4 (Re-
placeable Parts). In addition, it is necessary to
readjust the voltage drop across the series regula-
tor ("Preregulator Tracking" , Paragraph 5-103) and
to check the ripple imbalance as described in Steps
(a) through (e) of Paragraph 5-101.
2-27 POWER CABLE
2-28 A power cable is not supplied with the in-
strument. It is recommended that the user-supplied
power cable have three conductors (third conductor
grounded) and be of sufficient wire size to handle
the input current drawn by the supply (see Paragraph
2-16). Note that when the supply is operated from
a 115Vac source, the input current is approximately
double that shown in Paragraph 2-16.
2-29 REPACKAGING FOR SHIPMENT
2-30 To insure safe shipment of the instrument, it
is recommended that the package designed for the
instrument be used. The original packaging materi-
al is reusable. If it is not available, contact your
local Hewlett-Packard field office to obtain the
materials. This office will also furnish the address
of the nearest service center to which the instru-
ment can be shipped. Be sure to attach a tag to the
instrument specifying the owner, model number,
full serial number, and service required, or a brief
description of the trouble.
