to the far end of the cable under test, or to an intermediate fault and return.
Based on the selected Vp and the measured travel time of the test pulse,
the Fault Mapper calculates and displays distance.
The Fault Mapper measures distances to faults and cable lengths to an
accuracy of ± 2%.
This measurement accuracy is based upon the correct value of Vp being
used for the cable under test, and homogeneity of the Vp along the cable
length.
If the Vp is set incorrectly by the operator, or the Vp varies along the length
See § 4.9 for setting the Vp.
