6. OPERATING

6.1. TEST CABLES

The TEST function tests the attached cable based on the cable’s compliance with the

parameters stored in the tester for the selected cable.

To test a cable, perform the following procedure:

1. Select cable type under test.

2. Connect the cable under test to the QuickLAN and to the remote identifier.

3. Press TEST key.

Remote identifier is necessary due to obtain measurement with high accuracy level.

For twisted pair cables, when QuickLAN checks for a

cable remote identifier unit (ID) at the other end of the

cable and a pass condition exists, the LCD will display

the following information: good cable, remote unit ID#1

detected.

If testing coaxial cable with a termination, the tester

displays the total resistance of the cable wires and the

termination.



Only coaxial cables must be unterminated for the tester to display the cable’s length. If a

coaxial cable is open looks just like an unterminated cable, then a length measurement

that is less than the known cable length would indicate a possible open in the cable.

The tester if a failure is detected, additional information can be viewed with the ▼ ▲ keys.

The failure messages refer to individual wires rather than pairs of wires. The TEST mode

failure messages are described in following table.

Failure Display Description Failure Display Description

Miswire

Display the

incorrect wiring

of the end

connectors.

Pair Length

The length of

the pairs

within the

same cable

are abnormal

different.

Open

Display the

broken wire

and the

distance to the

break.

Split Pair

portion of

the cable

assembled

has split

pairs or a

poor quality

cable.

Tab. 1: Test failures

A short greater than 0Ω, will cause display a length greater than the actual distance to the

short. The tester uses 0Ω to calculate distance to a short.
