Referencing

Referencing methods
For referencing, only use the special test reference cords
contained as a standard assembly in your OLTS-85 test kit.
The reference method chosen will determine how many
connections are included in the loss limit.
In the following procedures, test-reference jumper cables are
assumed to be compliant to IEC 61280-4-1/4-2 in good
condition and have no end-face damage or debris.
Disconnecting the connection at the transmitter of the local or
remote MPOLS-85 after a reference is performed invalidates the
reference. Since the connection at the receiver is not glass-to-
glass, it can be removed without affecting the reference. Any loss
associated with the test-reference jumper cables is automatically
considered in the test results.
