ORGANIZATION OF THE SERVICE MANUAL 1-2.
The following descriptions briefly describe each section in
the manual.
SECTION 1. INTRODUCTION AND SPECIFICATIONS
This section describes use of the Service Manual and
application of special terminology (conventions) to describe
the meter’s circuitry. A complete set of specifications
appears at the end of this section.
SECTION 2. THEORY OF OPERATION
This section first categorizes instrument circuitry into
functional blocks, with a description of each block’s role
in overall operation. A detailed circuit description is then
given for each block. These descriptions explore operation
to the component level and fully support troubleshooting and
repair procedures defined in Section 3.
SECTION 3. MAINTENANCE
Provides complete maintenance information, from general
maintenance and cleaning instructions to detailed
troubleshooting and repair procedures to the component
level. Troubleshooting and repair procedures rely heavily on
both the Theory of Operation presented in Section 2 and the
Schematic Diagrams shown in Section 5.
SECTION 4. LIST OF REPLACEABLE PARTS
Includes parts lists for all standard assemblies.
Information on how and where to order parts is also provided.
SECTION 5. SCHEMATIC DIAGRAMS
Includes schematic diagrams for all assemblies.
