Cable tester

Functions
1.The testing function of low voltage battery: when the battery voltage is low, the test will be paused ,After power LED lights 5 seconds, the indicator LED will light one by one in sequence, it will repeat like this for 3 times, and again the power LED lights 5 seconds, then keep repeating like this ,In this case ,please change the battery.
2.No delay testing function: When one or more circuits ate open, for example the number 2.3.4.5 are open, the LEDs 1.6.7.8 will light by the main test apparatus and remote test apparatus, There is no any delay between lighting LED1 and LED6,With quick test, the flash time of LED is that the LED1 is on for 0.5 second and off for 0.5 second, the LED6 lights for 0.5 second and of for 0.5 second and off for 0.5 second, then keep repeating like thin.
3.Fast or slow test and the switch function
4.Short circuit test function
5.Open circuit test function
6.Wrong sequence test function
7.ACan test UTP cable (RJ-45 connectors),STP cable(RJ-11 connectors)
BCan test UTP cable (RJ-45 connectors),BNC coaxial cable
CCan test UTP cable (RJ-45 connectors),USB signal cable

Test methods
1.Connect one end of tested cable to main tester and other end to remote testing terminal.
2.Turn on the dial switch and select fast or slow. At that time its indicator lamp light.
3.In the case of right connection, if GND is not connected, the main tester indicators and remote testing terminal indicators flash from No.1 to No.8 one by one in cycle; if GND is connected, the main tester indicators and remote testing terminal indicators flash from No.1 to No.G one by one in cycle.
4.If connection is not correct, the display will perform according to the following situations: if one wire, for example No.2 wire, is in open-circuit, then the No.2 indicators do not flash . If several wires are in open circuit, then their relative indicators do not flash, If less than two wires are connected, al of indicators do not flash, If wires are connected in wrong order, for example N.2 and No.3 is wrong connected, and then its display is as follows: The main tester:1.2.3.4.5.6.7.8.G;he remote testing terminal:1.2.3.4.5.6.7.8.G
If wires are in short-circuit, for example No.2 and No.3 is in short-circuit, No.2 and No.3 indicators of both the main tester flash, but No.2 and No.3 indicators of the re
