Multimeter with TDR and short circuit tester.
This tester has a multi meter that you measure voltage, current, resistance and capacity, continuity and diode testing can test.
The TDR function ensures that the BNC cable can be accurately measured.
Also, the network cables and telephone cables are tested for short circuit and the breaking point can be found.
The TDR breakpoint will determine where that breaking point is and can indicate the distance in meters. The furthest away is 1200 meters.
Another option in this tester is the Fiber Optic Power meter.
This meter ensures that the power of the laser of the Video Fiber Optic transmission equipment can be tested.
Also, this option ensures that the Fiber Optic Patch cord can be tested.
