The indicator also indicates occurrences of motion detection and whether or not the ambient light level is exceeded.

Abstract: A pulse discharge site location (PDSL) system is provided which captures pulses on a conductor without requiring the triggering functions of an oscilloscope. The PDSL system comprises a pulse discharge measurement (PDM) system and is programmed to store the data captured by the PDM system in a reference buffer corresponding in size to the propagation time of a pulse along the length of the conductor. Samples of the captured pulses are scanned to locate the peaks of pulses above a selected noise level. These pulses are stored into a temporary working buffer, along with a selected number of samples, normalized and then added to the reference buffer. The reference buffer provides a statistical average of pulse activity. Primary pulses and their second and higher order reflections, as well as transient interference pulses and radio frequency interference, are indicated at the beginning and end of the reference buffer.
