CHAPTER 4: Setup
To determine the NVP of a cable with a known length, press 
(Measure) to capture the length of the cable using the displayed NVP. Use the down-arrow to highlight the NVP field and press ENTER. Use the up-arrow or down-arrow key to increase or decrease the value by 1% (percent) and adjust the NVP until the known length is displayed. The Length changes accordingly.
NOTE
The known cable must have a length of at least 50 feet or 15 meters.
To change the impedance, use the down-arrow to highlight the field and press ENTER. Use the up-arrow or down-arrow key to select the appropriate Impedance in Ω (ohms) from the predefined list.
To setup whether or not the cable is shielded, use the down-arrow key to highlight Shield: and press ENTER. Use the up-arrow or down-arrow key to make the appropriate selection. If “Yes” is selected, the wiring for the shield will be measured during the Autotest and used to determine if the Wiremap will PASS or FAIL.

With a | or | fiberoptic cable highlighted, press | (Edit) to |
edit an existing custom cable, or press | (New) to create a new fiber based on |
the GRI values of the highlighted cable. Cable Name and GRI @ 850 and 1300 can be viewed and changed.
NOTE
Default fibers cannot be edited.
