Problem: 
The loop length measurement on my Viavi ONX-580 is reading incorrectly. Is there some type of calibration that can be performed?
Solution: 
There are lead compensations for resistance and opens on the ONX-580. From either the Resistance or Opens test screen, press the Tray button in the bottom right of the front panel. There are softkeys there for Resistance Compensate and Opens Compensate. Press the required software key and follow the on screen instructions to compensate the test leads.
