5.2.2 PASS / FAIL decistions
Individual PASS / FAIL
Each result is equipped with a Pass/Fail judgement that applies to a limit, limit curve or
connectivity defined in the selected test standard. The worst result from all pairs or pair
combinations (worst margin or worst result) is marked with a bullet in front of the result.
Overall PASS / FAIL in Single Test
Each Single Test is equipped with an overall Pass/Fail judgement (the marked result is
considered for it).
Overall PASS / FAIL and Headroom in Autotest
At the end of Autotest an overall Pass/Fail (if all tests passed) result and Headroom are
shown on the display. Headroom is the worst case margin in the NEXT test that can be
used as a measure of the installation's condition when doing periodic inspections.
PASS /FAIL marked with an asterisk
When the measured results are close to the given test limit the accuracy of the
instrument could lead to an irregular Pass/Fail judgment. Such Pass/Fail warnings are
marked with an asterisk. In general it is recommended to treat such test results as
failed.
