* Measurement accuracy of <+/- 1% assumes the instrument
setting for velocity of propagation (Vp) of the cable under test to
be accurately set, homogeneity of the Vp along the cable length,
and accurate cursor positioning.
2.3 Accuracy
The Pro400 can measure distances to faults and cable lengths to an
accuracy of +/- 1%.
This measurement accuracy is based on 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 of the cable, then additional errors will be incurred, and
the measurement accuracy will be affected.
Note: The Vp is less well defined with unshielded multi-wire cable,
including power cable, and is lower when a cable is tightly wound
on a reel than when installed.
