Previous work sponsored by the Gas Research Institute lead to the development of the WaveForm Analyzer/Pulse Generator system far accurately and conveniently measuring IR Drop Free pipe-to-soil potentials. This technology has been optimized for application to dose interval potential surveys. It is now possible to record both current on and polarized potentials without the use of synchronous interrupters when performing dose interval surveys.
