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.
