Klein Tools VDV512-100 Coax Explorer Coax Explorer Repair

Curious about the KT VDV512-100 theory of operation. It maps tv coax cables, by plugging in a color coded plug on a coax cable and testing the end of other cables until the matching color LED illuminates, thereby identifying the 2 ends of the coax cable.

There are 4 colored plugs:

Blue 5.56K ohms between center pin and shell

Red 1.49K ohms

Green 14.93K ohms

Black 33.04K ohms
