FIBER METER

8. Press the

F3

button on Fiber Meter Unit B to

select

1300 nm

.

9. Press the

F4

button on Unit A to set the

1300 nm

reference.

NOTE

The Manual Power Meter mode allows you to set an optical
reference. The Manual Power Meter reference is only
retained while the unit is in the Manual Power Meter mode.
Setting a Manual Power Meter reference does not change
an Autotest reference set using the

CAL

function. See

Chapter 4

for specific information.

10. Connect the Fiber Meter handsets to the installed

fiber as shown in Figure 6-4. Loss measurements
are automatically displayed.
