Mastech MS6813 Multi Function Network Cable Tester
9
Open Circuit: Open Circuit is not commonly seen and therefore no indication is included in
the Tester. Typically there are 2 to 4 coaxial cables pairs in the network. Corresponding
indicators are off if RJ45 sockets are not connected with coaxial cable pairs. User debugs the
network with the wire pair indicators accordingly.
Short Circuit: shown in Fig.1.
Miswired: shown in Fig. 2: two pairs of wires are connected to wrong terminals.
Reversed: shown in Fig.3: Two wires within the pair are reversely connected to the pins in the
remote.
Split Pairs: shown in Fig.4: Split pairs occurs when the tip (positive conductor) and ring
(negative conductor) of two pairs are twisted and interchanged.
Note:
The Tester only shows one type of error per test. Fix one error first then make sure to perform
the test again to check other possible errors.
Test Mode
Follow the steps:
a)
Connect one of the wires to RJ45 transmitter socket.
b)
Connect the other end to RJ45 receiver socket.
c)
Turn the Tester power on.
d)
Press “TEST” button once to start testing.
e)
During the test press “TEST” button again to stop testing.
Example: wires pair 1-2 and pair 3-6 are short circuit. In test mode, the error indicators will
show as following:
1-2 and 3-6 indicators flash green lights, short circuit indicator flash red
light.
4-5 indicator shows green lights (no error)
7-8 indicator shows green lights (no error)
