operation or performance check (see Section 13) and suggests
possible causes and means of determining the defective
component. The schematic diagram in Section 5 and the
interior view of the test set given in Figure 15 will be helpful in
locating components. When ordering parts, always include the
Test Set serial number. The location of the serial number is
shown in Figure 15.
It is important that persons repairing the Test Set fully
understand the operation of the circuitry. When an assembly
fails, it may damage associated components and this possibility
must be evaluated prior to replacing an assembly. The circuitry
must also be understood so that measures may be taken to
prevent shock hazard to those making repairs.
When making repairs to this test set or replacing components,
the procedures outlined in the following paragraphs should be
followed.
Remove the Test Set from the case as explained in Section 11.
CASE REPAIRS
Because of its construction, a damaged lid or lower case will
require that both lid and lower case be replaced as a unit. The
replacement case is supplied with the instruction card and all
hardware so that the test set can simply be placed into it. The
case feet, carrying strap, and strap loops are accessible for
replacement after the test set has been removed from the case.
REPAIRS TO COMPONENTS OF CHASSIS AND PANEL
In most cases any work will require separating the panel and
chassis. To do this, follow steps below:
1.
Remove both guard screens.
