Certifying Duplex Cable Using Test Method B 

All necessary certification test information is displayed and all required certification tasks are available from the Autotest menu to maximize 
productivity.  If the fiber optic link uses non-SC style connectors refer to Appendix B for certifying using the modified test method B 
setup. 

 
To begin certifying links:  
  
1.

 

Verify that the Project settings are correct. 

2.

 

Attach the correct adaptors for the link type under test. 

3.

 

Attach the SCT Primary and Secondary devices to the ends of the link. 

4.

 

Press the [TEST] key. The [ESC] key can be pressed to stop the test at any time. 

5.

 

During the test the Circuit ID can be changed in order to save time.  If the Circuit ID is correct no action is needed. 

6.

 

When finished the overall test result is displayed.  At this time you may: 

 

Change the Circuit ID 

 

Save the result 

 

View the result 

 

Run another Autotest 

 

Exit the Autotest Menu.

Do not disconnect the reference cords from the output
connectors.               Disconnecting the reference cords from
the output connectors will invalidate the reference setting.
