TC-350 DMM/TDR Cable Fault Locator

TC-350 DMM/TDR Cable Fault Locator

TC-350 DMM/TDR cable fault locator is designed for ease of use. It combines with both time domain reflectometer (TDR, pulse reflection) testing and digital multi-meter (DMM) testing. TC-350 can measure the exact fault location such as the broken line, cross faults, earthing, poor insulation, poor contact of the lead covered cables&plastic cables; it also can test AC/DC voltage, insulation, capacitance, loop resistance. It can test almost all the telecom cables. Simply select the modes which you are going to use. Distance, VOP, Gain and Range are automatically selected and adjusted. Just move the cursor to the fault to pinpoint its location.
