What is a TDR Meter and how do I use it?

It sends an electrical pulse into the connected cable, traveling along the cable until it reaches the fault and then that pulse is sent back to the TDR. The time it took for that pulse to reach the fault and travel back is measured and converted to a distance reading that will appear on the TDR Meter.
