7.16 VF Auto Test
Note: This is a Single-ended test.
The VF Auto test quickly evaluates a cable to see if it is acceptable for voice frequencies based on pre-
defined PASS / FAIL criteria. The VF Auto test will perform a DMM test, Load Coil test, a Capacitive
Imbalance test and a Longitudinal Balance test. If a Load Coil is found, the distance to the Load Coil is
given.
1. From the Main Menu, select VF AUTO (function button F4). This test will take place automatically.
