cable tester scanner 1.check open ,short circuit status and DC polarity 2.scan and find the cable you want

          cable testing scanner SML-868TS       

Function and Features  

1. To scan and search the cable(RJ45,RJ11) wanted among  numerous ones.  And you can test common lines by alligator clip attached.

2. To test rapidly the point of open or short circuit and detect the line sequence.

3. To test the circuit status:    

a). to test the direct-current level and determine the positive or negative polarity    

b). to test the ring-current signal    

c). to test the opening or short circuit in line.

4. To adjust the sensitivity by adjusting the volume.

5. With a earphone function, you can put on the earphone for working while it is noisy.

working current: emitter≤20mA,Receiver≤50mA.

Power supply: DC, 9V superposition battery

Signal distance: ≥ 3000M

About security: safety in use( you can directly connect the probes with the naked wire lines for testing)
