A high performance measuring instrument with multifunction designed for testing FTTx network. It’s mainly used to measure the physical characteristics of optical fiber under test, such as the length、the transmission loss and the splice loss etc.. It can also locate the faults or breaks of optical fiber. It's widely applied in the manufacture, construction and maintenance in optical fiber communication system.
1. Push function switchover button on emitter to the position of “TEST”. When the red status indicator flashes, it means that you already enter into this function.2. Insert the network wire which two ends are both RJ45, into the corresponding ports of emitter and receiver.3. Check the lighted sequence of LEDs of receiver. If the lighted sequence is same as the network cable’s wire sequence, the sequence is right; otherwise, the wire sequence is wrong.➢ Short Circuit and Open Circuit Test1. Push function switchover button on emitter to the position of “SCAN”. When the status indicator turns to red, voltage indicator “+ -”bright, it means that you already enter into short circuit and open circuit testing function2. Choose a line firstly. Clamp two copper wire sections respectively by crocodile clamps of emitter. In case of short circuit, then the voltage indicator light of emitter “+ -” will be extinct. If the indicator is light, it means open circuit.
