2.3 Accuracy
The RapidTrace 1200 is able to 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 and accurate positioning of the cursor (see section 4.1).
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 multicore cable,
including power cable, and is lower when a cable is tightly wound on a
drum than when installed.
