If equipment fails a test performed by collating test equipment, the test equipment should indicate which signal(s) are out of tolerance.
Additional Information:
Collating test equipment presents the results of two or more checks as a single display; for example, a "test passed" light illuminates only if all of the relevant signals are within tolerance. Collating test equipment reduces the number of displays the maintainer must read, thereby reducing testing time. However, it should identify the out-of-tolerance signal(s) rather than merely indicating that the equipment failed the test.
