Fluke DSX-600 - Loop Resistance

Loop Resistance results show the DC loop resistance for each wire
pair. The remote puts a short at the end of each pair to make the
loops. A pair’s resistance depends on the quality of the contacts in
the connector, the length of the pair, and its wire gauge. Figure
27 shows the loop resistance results screen.
Resistance problems always affect other tests. For example:
 A link that is too long has too much resistance and will fail the
length test.
 High-resistance connections reflect signals, which causes the
return loss test to fail. Use the tester’s HDTDR analyzer to see
the distance to the bad connection.
Refer to Figure 27:
 VALUE is the DC loop resistance for each pair.
 LIMIT shows only if the selected test limit includes a limit for the
loop resistance test.
 The overall result for the loop resistance test. This result is for a
test with the ISO11801 Channel Class Ea limit, which has a limit
for the loop resistance test. Some test limits do not have a limit
for this test. When no limit is available, the tester shows an .
