Function:
1. Testing correspondingly doublet - wisted cables 1, 2, 3, 4, 5, 6, 7, 8, and G,
meanwhile, judging wrong connection, short circuit and open circuit.
2. JV505B tests cables of BNC, RJH and RJ45
3. JV505C tests cable of RJ11 and RJ45
Operation:
1. Double-twisted cables
Switching on the power
Main Tester: 1-2-3-4-5-6-7-8-G
Remote Tester: 1-4-3-2-5-6-7-8-G
2. Following are abnormal connections:
(1) If one cable, for example, Cable NO.3 is open circuited, the two
NO.3 lights of the main tester and remote tester will not turn on.
(2) If several cables are not connected, several lights will not turn on respectively. If
less than two cables are connected, none of the light is on.
(3) If two ends of a cable is disordered, for example, NO.2 and NO.4, then displays on:
Main tester: 1-2-3-4-5-6-7-8-G
Remote: 1-4-3-2-5-6-7-8-G
(4) If two cables are short circuited, neither of the corresponding lights is on of the
remote tester while main tester remains unchanged. If three cables, including three, are short circuit, none of the corresponding light is on.
