NF-468B line measuring instrument, measuring network, telephone, computer network, BNC monitoring line tester
Using automatic scanning, fast test, streamlined shape, ergonomic design.
Smooth lines simple, drop, light design, more in line with the site construction.
Test cable: RJ11, RJ45, BNC cable
Power supply: DC 9V laminated battery
Power consumption: 25MA
Volume: 10.5 * 10.5 * 2.6 mm
Packing list: Host auxiliary machine BNC adapter line instructions (without battery)
First, the function:
1. pairs of twisted pair 1, 2, 3, 4, 5, 6, 7, 8, G line by root (on) test, and can distinguish between which root (right) wrong line, short circuit and open circuit.
2. Switch ON is the normal test speed, 'S' is the slow test speed, M is the manual gear.
Second, the twisted pair test: turn on the power, the cable plugs were inserted into the main tester and remote tester,
The host lights are flashing from 1 to G one by one. Legend:
Main tester: 1-2-3-4-5-6-7-8-G
Remote Tester: 1-2-3-4-5-6-7-8-G (RJ45)
1-2-3-4-5-6 ------ (RJ12)
If the wiring is not normal, according to the following circumstances:
1. When there is a cable such as line 3, the main test instrument and remote test side 3 lights are not bright.
2. When there are several lines nowhere, then several lines are not bright, when the cable is less than 2 lines connected, the lights are not bright.
3. When the two lines out of line, example 2, 4 line out of order, the display is as follows:
Main tester unchanged: 1-2-3-4-5-6-7-8-G
The remote test end is: 1-4-3-2-5-6-7-8-G
4. When the cable has two short circuits, the main tester does not show up, and the remote test shows two short-circuit lights are slightly bright, if there are three or more (including three) short-circuit when all the short-circuit The line number of lights are not bright.
Third, if the test patch frame and wall module, you need two matching jumper (such as 110P4-RJ45) led to the tester.
Fourth, coaxial cable test: If the cable is good, then the two ends of the BNC lights at the same time flashing green light.
5, BNC line test instructions
1, toggle the dial switch, select fast or slow block, power indicator light.
2, connect the BNC test line to the BNC head of the main tester and the other end to the BNC head of the RJ45 to BNC wiring and connect the RJ45 of the wiring to the remote test terminal RJ45 interface. The main tester indicator and The remote test end lights 1 to 2 are shiny and loop.
3, if broken, out of order short circuit as shown in the test method.
4, the test is completed, turn off the power, power indicator off.
