6.2. CABLE LENGTH MEASUREMENT

The tester measures the length of both twisted-pair and coaxial cables. If the tester is not

calibrated to the cable under test, then factory default cable characteristics 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 perform “Test Cables” described on this

manual to prevent any cable failures from corrupting the length measurement.

Cable length measuring 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

between pairs is uncommon. Coaxial cables must be unterminated for the tester to display

the cable’s length.
