Figure 3
The image presents a detailed diagram of a specimen setup designed for measuring thickness. It features a rectangular specimen with clear markings indicating dimensions of twenty-four units in length, sixty units in width, and five units in height. The axes are labelled as X, Y, and Z, with arrows pointing through the origin. Various components are annotated, including contacts for electrical measurements and references to resistance values such as R sub h and R sub s. Additional elements like a slide and measurements for contact arrangements are noted, alongside a gauge indicating an angle with reference to vertical settings. Various symbols and lines demonstrate how the components connect and function within the measurement system.Specimen with schematic overlay of the measurement setup for four-wire resistance measurement. RS(hl,ws) = resistance of the specimen depending on the layer height (hl) and strand width (ws), RFL = resistance force lead, RSL = resistance sense lead, IFRC = forced current, UFRC = voltage needed to force current, USNS = measured voltage drop across specimen
