When to Set the Reference
Note
At the job site, turn on the testers and let them sit
for a minimum of 5 minutes before you set the
reference. Let them sit longer if they are above or
below ambient temperature.
The tester requires you to set the reference at these times:
• When you change the CertiFiber Pro module in the main or
remote tester.
• When you use a different remote tester.
• When you change the Reference Method in the test setup.
Set the reference also at these times:
• At the start of each day, at the job site, then at regular
intervals during the day. For example, set the reference when
you start tests on a different series of fibers.
• When you connect a test reference cord to the module’s
output port or to another source, even if you connect the
same test reference cord you connected before.
• When the tester tells you that the reference is out of date.
• When a loss measurement is negative. This occurs when there
was a problem when you set the reference. For example, an
endface was dirty or the testers were cold.
WCaution
Do not disconnect the test reference cords from the
modules’ output ports after you set the reference. If
you do, you will change the amount of optical
power that enters the fiber and the reference will
not be correct.
