Set the Reference
The reference serves as the baseline power level for loss
measurements.
Set the reference at these times:
•
At the beginning of each day using the remote end setup you
will use that day.
•
Anytime you reconnect a test reference cord to the module’s
output or other source.
•
Anytime the tester warns you that the reference is out of date.
•
Anytime you see a negative loss measurement. (See the
Technical Reference Handbook for more information.)
•
Anytime the tester tells you to set the reference.
