HOW TO USE THE PERFORMANCE TEST CHARTS. (CONT)

Equipment Instructions are contained in a rectangular box. They provide details concerning proper

hookup of test equipment and correct control settings necessary to perform the test procedure.

The initial equipment instructions found at the beginning of each chart reference a sheet number

where an equipment test setup diagram can be found. The sheet number Is located at the top of each

page of the chart, below the chart number and title.

Within a test procedure, changes of equipment control settings, and even hookups, are often

required. These changes are detailed in the equipment instruction boxes. At any step in the chart,

the equipment status is always that defined by the nearest previous equipment Instruction box in the

chain.

TEST PROCEDURE INSTRUCTIONS

This rectangular box provides general test procedure instructions,

DECISION DIAMOND

As a result of a particular test point probe, some electrical value should be observed, such as a power

indication on a power meter. The decision diamond defines what value should be observed, and per-

mits a yes or no decision in response to what is observed.

FLOW LINE

Flow lines provide direction to successive steps in the logic chart. An arrow at the end of each flow line

indicates the next step in the procedural chain.

INTERNAL CONNECTOR IDENTIFIER

There are two sizes of circular identifiers used in the charts. The smaller of the two is the internal

connector identifier. The internal connector identifier indicates a continuation of the procedure to

another sheet in the same flow chart. The sheet on which the procedure is continued contains a

corresponding identifier, ie, a small circle inwhich the same number and letter are printed. The

number in the circle Indicates on which sheet the test procedure continues. For example, in the

sample flowchart the NO branch of the decision diamond flows to the identifier containing 2A. This

means that the procedure is continued on sheet 2, at the small circle containing 2A.

CORRECTIVE ACTION OR ADDITIONAL INSTRUCTION

A corrective action or additional instruction box always follows a decision diamond. If a test set re-

sponse does not meet the standard set in the decision diamond, the appropriately marked flow line

from the decision diamond will be followed to a corrective action box, which contains a specific trou-

bleshooting reference. if the test set response meets the standard, the flow line will be followed to an

additional instruction box, which will either continue with the same performance test, or state that the

equipment has met all this performance test's standards and refer to the next performance test.
