Pair and Length measurement (PAIR & LENGTH) function:
Whether or not there is a far-end recogniser, (ID), at the far-end of the cable, the
LAN Network Cable Tester is capable of carrying out a ‘Pair and Length’ (PAIR
& LENGTH) measurement. Therefore, the far-end recogniser, (ID), can remain
connected during a wiring diagram, (WIREMAP), and pair and length (PAIR &
LENGTH) measurement. This avoids it being repeatedly inserted and removed.
When the pair and length (PAIR & LENGTH) measurement function is selected, the
LAN Network Cable Tester display will display an image typical to that shown below
as the measurement is being made:
Note: Due to different technical parameters in various branded cables, the user should carry
out the LAN Network Cable Tester Dynamic Calibration function before making a length
measurement. (See page 12)
Test 1: Short circuit (SHORT)
The LAN Network Cable Tester will display an image typical to that shown below if
there are any short circuits on the cable or terminal, (12 short circuits are shown in
the example below).
(The tester cannot show the exact location of the short circuit). Press the
p
or
q
key to restart the test or press the ‘PAIR&L’ key to return to the main menu.
Always correct a short circuit error first and then start further test measurements.
