Four wire measurement

In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements than the simpler and more usual two-terminal (2T) sensing. Four-terminal sensing is used in some ohmmeters and impedance ana… WebFigure 2. Simplified equivalent circuit (2-wire measurements) in an SMU. In addition, while sourcing current or voltage, SMUs can simultaneously measure both current and voltage. Figure 2 represents a single SMU channel, and this channel can exist as a standalone product or as one SMU channel within a mainframe that supports multiple SMU channels.
