Network cable tester without batteries.
Test cable: RJ45, RJ11
Power Type: DC 9V laminated battery
Power consumption: 25mA
First, the features:
1 twisted pair 1,2,3,4,5,6,7,8 G line to root () test can distinguish the decision which one (on) the wrong line, short circuit and open circuit.
2 Switch ON the normal test speed, "S" for slow test speed.
Second, the twisted-pair test: turn on the power, put cables into both main tester and remote tester, the host from 1 to G-by-flash sequence, the following legend:
Main tester :1-2-3-4-5-6-7-8-G
Remote tester :1-2-3-4-5-6-7-8-G (RJ45)
If the wiring is not normal, according to the following circumstances:
1 when there is a network cable, such as the 3rd line circuit, the main tester and remote tester lights are not bright.
Barrier when there are a few lines, a few lines are lit, when less than two cable line connectivity, the lights are not bright.
When two network cable out of order, for example, the 2,4 line out of order, as follows:
The main tester invariant :1-2-3-4-5-6-7-8-G
Remote tester :1-4-3-2-5-6-7-8-G
Two short-circuit when the network cable, the main tester does not light, the remote tester short-circuit the two wires of the lights are bright and tiny, if there are three or more (including 3) short-circuit all the short-circuit few lines the lights are not bright.
Third, if the measured patch panels and wall seat module, you need two matching jumper lead to the tester.
, Coaxial cable test: If the cable is good, both ends of BNC lamp flashes green at the same time.
