ESULTS
At the completion of the Length test, the screen displays the summary
results.
1. Press START (F1) to restart the Length test.
2. Press DETAIL (F3) to view more information about the Length test
results.
3. Press PDELAY (F2) to view the Propagation Delay for each pair.
NOTES
1. Some variation in the measured length of wire pairs within the same
cable is considered normal. This is due to the difference in construction
of the individual pairs.
Length variation from pair to pair will be greater for longer cable lengths.
2. An asterisk (*) next to a PASS result indicates that the measured value
is close enough to the standard input that it is within the SCAN-LAN Vt’s
measurement uncertainty.
3. When measuring spooled and other uninstalled cables, the cable
length will probably be greater than the specification test limit. This will
cause a FAIL Length test result. In this case, you may ignore the fail
message.
4. A cable found to have a “short” will cause length test to FAIL
regardless of measured length.
