Fluke 825A - How to Obtain Parts; Reference Designation

SECTION V
LIST OF REPLACEABLE PARTS
5-1. GENERAL
a. The following six assembly lists describe all nor-
mally replaceable parts of the Model 825A, 825AR,
825A/AG, and 825AR/AG Differential DC Voltmeters.
Each list has a corresponding illustration on which the
parts for that list are pointed out. Parts are called
out on both lists and illustrations by reference desig-
nations from the schematic diagram. ThoSe parts
(mechanical) which have no reference designation are
shown on the illustrations by Fluke stock number.
b. A Use Code column is provided to identify certain
parts that have been added, deleted, or modified during
production of the 825A. Each part for which a use code
has been assigned may be identified with a particular
instrument serial number by consulting the Use Code
Effectivity List at the end of this section.

DESCRIPTION
5-2. HOW TO OBTAIN PARTS
a. Standard components have been used whenever pos-
sible. Thus, most parts may be obtained locally, How-
ever, Special components are used in some instances.
All parts manufactured or altered by Fluke and all parts
for which Fluke controls the design are designated by an
asterisk preceding the Fluke stock number. All struc-
tural parts and special parts should be purchased from
your local Fluke representative or from the factory.
b. When ordering parts always include:
(1) Reference designation, description, and Fluke
stock number.
(2) Instrument model and serial number.
(3) Most structural parts are not listed. In this case,
give complete description, function, and location for
the part.
