5.5 General information. General information shall be displayed before the start of testing and shall include all WARNINGS and CAUTIONS applicable during the test, as well as the following information:

a. A list of supporting programs, if applicable. b. ICD accessory equipment.

c. Related equipment publications.

d. Special operator requirements for UUT testing. e. Program date and revision identifier.

f. Identification numbers of compiler, run time system, and equipment tables required. g. Serial number of the ATE system used.

5.6 Error control.

5.6.1 Error correction. Where operators are required to make entries into the system, the display sequence shall provide an easy means for correcting erroneous entries.

5.6.2 Internal software checks. The operator shall be notified, to the maximum practical extent, of any input errors detectable by internal software checks for validity of item, sequence of entry, completeness of entry, etc.

5.6.3 Critical entries. The user shall be required to acknowledge critical entries prior to their being implemented by the system.

5.7 Fault messages.

5.7.1 Diagnostic responses. Responses, directed primarily toward the repairman (not necessarily an

ATE operator), shall occur as either replace statements or adjustment messages.

5.7.2 Replace statement. Replace statements must identify a specific defective component or a component ambiguity group. The defective components called out in an ambiguity group shall be listed in descending order of failure probability; however, high-cost components may be placed last or separately, upon Government approval. The tern\m last or separately, upon Government approval. The term "REPLACE" shall be used in all fault statements, (e.g., "REPLACE SUBASSEMBLY A1" or "REPLACE R1, C1, VR1").
