If the resistance is lower then 30
Ω
±
20Ω
, the buzzer
will sound.
CABLE TESTING (eg double twisted cables)
1. Insert cables to be tested into both main unit and
remote tester sockets and turn the RANGE switch to
AUTO.
2. The LED
’
s on both units should illuminate in sequence
from 1 through to G for RJ45 cables and 1 through to 6
for RJ11 cables as below.
Main unit: 1-2-3-4-5-6-7-8-G (RJ45)
Remote unit: 1-2-3-4-5-6-7-8-G
Main unit: 1-2-3-4-5-6 (RJ11)
Remote unit: 1-2-3-4-5-6
FAULT DESCRIPTIONS
1. If one cable is open circuit eg. no.3 then the no.3 LED
on both units wont illuminate.
2. If a number of cables are open circuit then those
number LED
’
s wont illuminate. If less than 2 cables are
connected properly, none of the LED
’
s will illuminate.
3. If 2 cables are connected in the wrong order then the
LED
’
s will illuminate in the same incorrect order. Eg. If
no.2 and no.4 are twisted then the 2 displays will read as
below:
Main unit: 1-2-3-4-5-6-7-8-G (RJ45)
Remote unit: 1-4-3-2-5-6-7-8-G
