Test results for underground DC leakage are clearly displayed as an analog bar graph along with an indication of a good or faulted cable. A self-contained 8 kilovolt-high voltage source powers the tester using a 9 volt lithium battery, making the UCT-8 a compact single hotstick operation tool for testing cable.
There is also integrated safety circuitry that detects cables which have not been properly de-energized, alerts the user of the problem and shuts down the test to prevent system damage. An automatic shutoff feature helps the battery to last longer.
