This article describes a new online streaming potential instrument, called a streaming potential system (SPS), which provides two measurement signals, an absolute signal and a relative operating signal. The absolute signal measures the net charge density with charge polarity and magnitude, in which the neutral charge point is always displayed as zero. The relative signal is adjustable so that the zero point can be set to the desired operating point. Operators can use the absolute signal to determine the theoretical operating point. The relative signal is used when the desired operating point is different from the theoretical point.
