Determining a Cable's Actual NVP

You can determine a cable's actual NVP by adjusting the
measured length to match a known length of cable.
To determine a cable's NVP:
1 Connect a known length of the cable to be tested to
the tester's twisted pair or coaxial connector. The
cable length must be as follows (as measured using
the tester's default NVP values):
•
Twisted pair: 34.4 ft to 689.7 ft (10.5 m to
210.2 m)
•
Coaxial: 40.3 ft to 807.9 ft (12.3 m to 246.2 m)
Tip: For maximum accuracy and adjustment resolution,
use a cable between 45 ft and 70 ft (14 m and
21 m) long.
Calibrating Length Measurements
The cable must not be connected to a wiremap
adapter, port, or other device.
