Abstract: A terminator plug is connected to one coaxial cable connector and a coaxial cable connection tester is connected to the other cable connector. A voltage is applied to the cable's center conductor and a ground to the cable's shield. The center conductor voltage is monitored for open and short faults while the cable adjacent first one and then the other connector are wiggled. The voltage on the center conductor changes if a continuous short or open is present or if such faults intermittently occur. The voltage on the center conductor is monitored by two comparators with one detecting short faults and the other detecting open faults. The outputs of the comparators are combined to generate an OK signal if no faults are detected. If open faults are detected, the signals from the open comparator are clocked into a flip-flop; if short faults are detected, the signals from the short comparator are clocked into a flip-flop.

Abstract: A resistance tester is incorporated into a grounding device. The resistance tester includes a test circuit, a battery, a switch and a set of indicator devices. With the grounding device being worn and the cord end of the device in contact with the user so as to form a closed circuit, the test circuit measures the resistance level of the grounding device upon activation of the switch. The indicator devices provide a visual indication of the resistance level, i.e., too high, too low or within acceptable limits. The resistance tester is self-contained and may be used anytime by the user to ensure that the resistance of the grounding device is acceptable.
