Press button below [SAVE] or [CANCEL]
For example, if you select a loss pass value of 2 dB, and a loss
Marginal value of 3 dB, then any loss less than 2.0 with be a pass
(indicate by
‘
✓
’ on LCD), and values from 2.0 ~ 3.0 will be marginal
(indicate by alternating ‘ ✓ ’ & ‘X’ on LCD). Values more than 3 dB will
be a fail (indicate by ‘X’ on LCD).
Setting Pass, Marginal, Length values to 0 disables the pass/fail check
function.
Pass/Fail Operation
During either One-Way or Two-Way Autotest,
•
Loss test status for each wavelength will be shown with a
‘
✓
’ (pass) or ‘X’ (fail) or alternating ‘
✓
’ / ‘X’ (marginal) on the
right of LCD. If the length (only in 2-way Autotest) test fails,
the displayed value will flash.
•
An overall test result, “PASS” will be shown at the top right
corner of LCD if:
-
pass/fail check function is disabled.
- loss test statuses of all wavelengths (and length test
status in the case of 2-way Autotest) are pass or
marginal.
- An overall test result, “FAIL” will be shown at the top
right corner of LCD if, loss test status of any wavelength
(or Length test status in the case of 2-way Autotest) is
fail.
•
Pass/fail method selection:
For 2-way Autotest:
- if ‘WC’ (worst case) is selected, the worst-case loss
value will be used to determine the test status.
- If ‘AV’ (average) is selected, the average loss value will
be used to determine the test status.
For 1-way Autotest:
Worst case loss value will always be used to determine the
test status regardless of the selected pass/fail method.
