Information
I. 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.
2. No delay testing function:
When one or more circuits are open, for example the No. 2,3,4,5 are open, the LEDs 1-6-7-8 will light by the main test apparatus &; 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 off for 0.5second ,the LED7 is on for 0.5 second and off for 0.5 second, the LED8 is on for 0.5 second and off for 0.5 second ,then keep repeating like this.
3. Fast or slow test and the switch function
4. Short circuit test function
5. Open circuit test function
6. Wrong sequence test functio
7. SK-518U can test UTP cable (RJ45 connectors ),USB
signal cable.
II. 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 conn -ected, 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 indic -ators 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, all of indicators do not flash. If wires are connected in wrong order, for example No.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
The remote testing terminal:1-3-2-4-5-6-7-8-G
If wires are in short-circuit, for example No.2 and No.3 is in short-circuit,No.2and No.3 indicators of both the main tester flash, but No.2 and No.3 indicators of the remote testing terminal do not flash.
III. Instructions for using
1. Turn on the dial switch and select¡°Fast ¡±or ¡°slow¡±,at that time its indicator lamp light.
2. If connecting UTP cable (RJ45 connector),the main tester indicators and remote testing terminal indicators flash from No.1 to No.8 one by one in cycle; if connecting USB signal cable, the main tester indicators and remote testing terminal indicators flash from No.1 to No.4 one by one in cycle.
3. The testing methods for disconnection, wrong order connection and short-circuit are the same as that mentioned above.
4. When the inspection is finished, press down power button to turn off the inspector, then its power indicator turned down .
