Deleting or Inserting a Wire Gauge Entry
To delete the information in a complete Section number line, select the desired
section using F or H, then press C(
To insert a section, position the cursor to the section above which you want to
add a line, and press B (Insert Section).
RFL Test "Distance to Strap" Entry
If the distance to the strap was known and entered into Section 1 of the above
Multiple Gauge entry screen (along with
section data will be ignored. The RFL fault distances will then be based on a
wire resistivity that is calculated from the entered strap distance.
If the cable contains one or more gauge changes between the tester
and the far-end strap, the average resistivity calculated from the
entered strap distance could result in inaccurate distance-to-fault or
fault-to-strap readings, depending on the relative lengths of the
different gauges.
Short or Double-Sided Fault Location (3 Wire) Test Results
To view test results for a short or double-sided fault, select the desired
strapping option to complete the bridge (as prompted in Figure 4-13).
If the fault is a short or if both conductors are faulted, you must use
either a good conductor or pair to complete one leg of the bridge. It is
best to use a separate good pair for the leg because it can be any
length or gauge. If only one good conductor is available, it can work
as well, but it must be the same length and gauge as the faulted pair.
