Preparation

Test equipment items 1 through 9 in Table 4-1 are required to accomplish a complete Performance Check. At the beginning of each subsection, in both the "Performance Check Procedure" and the "Adjustment Procedure" sections, there is an equipment-required list showing only the test equipment necessary for performing the steps in that subsection. In this list, the item number that follows each piece of equipment corresponds to the item number listed in Table 4-1.

This procedure is structured in subsections, which can be performed independently, to permit checking individual portions of the instrument. At the beginning of each subsection is a list of all the front-panel control settings required to prepare the instrument for performing Step 1 in that subsection. Each succeeding step within a particular subsection should then be performed, both in the sequence presented and in its entirety, to ensure that control-setting changes will be correct for ensuing steps.
