SCAN-LAN VI
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 VI’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.
5. OPEN or SHORT usually indicates that a pair ends in an open or a
short. However, if the remote unit is used, an OPEN result should be
displayed for each pair.
6. Propagation Delay is the time in nanoseconds for a pulse to travel the
length of a twisted pair.
7. For instruction on changing length units (feet/meters), refer to
Chapter 9, Setup.
