Abstract
In some embodiments, an apparatus includes a substrate having a smoothly bending surface to fit into a human hand. The substrate includes a start test switch, a first connector to couple to a first end of a cable, and a second connector to couple to a second end of the cable. The cable has an impedance. The electronic circuit is coupled to the, first connector and the second connector. In operation, the electronic circuit provides a first signal when the first end of the cable is coupled to the first connector and the second end is coupled to the second connector, the start switch is activated, and the impedance is between a minimum impedance value and a maximum impedance value. The electronic circuit provides a second signal when the first end of the cable is coupled to the first connector and the second end is coupled to the second connector, the start switch is activated, and the impedance is greater than the maximum impedance value.
