4-4. GENERAL.
This section describes the UUT test for the day sensor subassembly. It includes an explanation of the
way testing is accomplished and a description of the test.
4-5. TEST CONCEPT.
The UUT test for the day sensor subassembly is supplemented by procedures in section III of this
chapter, and by illustrations in section IV. While you are performing the UUT test, message prompts on
the VDT will direct you to perform one of the procedures in section III, or to locate a part of the day
sensor subassembly in section IV.
a. Procedures. Section III contains procedures to install and remove the day sensor subassembly and
the insert/adapter from the dayside test bench. These procedures do not apply to the UUT test until
called for by the test program. At the appropriate time during the test, a message prompt on the VDT will
direct you to perform the procedures in one or more paragraphs in this section. At that time, turn to the
referenced paragraph and perform those procedures, as the program cannot continue until they have
been performed.
b. Illustrations. Section IV contains illustrations showing the locations of key components of the day
sensor subassembly, the mounting locations of certain items, the test setup when using the transit level,
lens accept/reject criteria, and locational information for the resolution target and reticle alinement. At the
appropriate time during the test, a message prompt will refer to an illustration in section IV. Turn to the
referenced illustration for assistance while performing the following instructions on the VDT.
4-6. TEST DESCRIPTION.
When the UUT test program has run the selected self-tests and is ready to test the day sensor
subassembly, the following menu will be displayed on the VDT:
SELECT DESIRED MENU OPTION FROM LIST BELOW:
1. RUN HARNESS TEST
2. RUN ELECTRICAL TEST
3. RUN OPTICAL TEST
4. RUN ALL TESTS
ENTER OPTION NUMBER AND PRESS <RETURN>.
