DESCRIPTION
Miswire
Display the incorrect wiring of
the end connectors.
Open
m
Display the broken wire and
the distance to the break.
Pair Length
m
Indicate that the length of the
pairs within a cable are
abnormal different.
Split Pair
A portion of the cable
assembly has split pairs or a
poor quality cable.
B). Cable Length Measurment
The tester measures the length of both twisted-pair. If the
tester is not calibrated to the cable under test, then factory
default cable characteristisc are used to compute the length.
If a more accurate length measurement is desired, refer to
“CALIBRATING CABLE LENGTH” described on this manual.
Before a length measurement is made, the tester performs
“Test Cables” described in this manual to prevent any cable
failures from corrupting the length measurement.
Cable length measure procedure.
1. Select cable type under test.
2. Connect the cable and test to the appropriate connector on
the tester.
3. Press LENGTH key.
4. Use ▼or ▲key to scroll selection multiple displays.
The information that is displayed depends on the type of cable
selected. For twisted pair cable, each pair has corresponding
length measurement.
A 5% difference in length botween pairs, is uncommon.

C). WIRE MAP CHECKING
Use the tester wiremap function and remote identifier unit (ID),
to determine the wiring status of both the near end and far end
of the cable.
