REPLACEABLE PARTS
INTRODUCTION
This section contains information for ordering parts. Table 6-1 lists the exchange assem-
blies available. Table 6-2 lists (1) the names and addresses of manufacturers which cor-
respond to the manufacturers’ code numbers and (2) reference dçsignator definitions and
abbreviations used in the replaceable parts list. Tables 6-3A, 6-3B and 6-3C are the re-
placeable parts lists for the HP 85027A, 85027B and 85027C respectively. They list the
replaceable parts in reference designator order. Table 6-4 lists the replaceable pai-ts of
A2 Circuit Board, common to all three bridges.
Figui-es 6-lA, 6-lB and 6-iC show the major assembly and miscellaneous parts locations
for the 3 bridges. The circuit board assembly (A2) for all 3 bridges is the same. Figure
6-2 shows the component side, Figure 6-3 shows the solder side, Table 6-2 lists its re-
placeable parts.
EXCHANGE ASSEMBLIES
You may replace, on an exchange basis, the bridge microcircuit assembly and realize a
considerable cost saving. This assembly includes the input and test port connectors and
the reference termination. Table 6-i lists these factory repaired and tested assemblies
and theii- HP part numbers. The defective assemblies must be returned for credit to
m~ealizethe cost savings. Thus, assemblies required for spare parts stock must be ordered
by the new assembly part number.
