Measuring Power or Loss (FPM-600)
Setting Pass/Fail Thresholds
Setting Pass/Fail Thresholds
You can define thresholds to specify acceptable power (dBm) or loss (dB)
values for each wavelength. Thresholds are often supplied by system
manufacturers and depend on the system deployed.
When a threshold is activated, the PASS/FAIL
LED is turned on. If it is green, the threshold succeeded, if the PASS/FAIL
LED is red, the threshold failed.
To set pass/fail thresholds:
1.
From normal operating mode, press
repeatedly until you reach

.
to access the first submenu, then
repeatedly until you reach the
P/F
2. Pres s

menu.
3. Press
to switch between power (dBm)
and loss (dB) values.
4.
Press
to switch between available wavelengths. An asterisk (

)
appears beside activated thresholds. If no threshold is set for a
wavelength, the unit indicates “
----
”.
5.
Press
to activate/deactivate the displayed threshold. The
PASS/FAIL LED will light (green or red) when you return to normal
mode.
