Nagy sheet resistivity measurement
WitrynaThe primary technique for measuring sheet resistance is the four-probe method (also known as the Kelvin technique), which is performed using a four-point probe. A four … Witrynameasure voltage or resistance using a four-wire method to prevent the lead and contact resistance from affecting the measurement. The Model 2450 enables the user to specify the test current, measure the resistance using offset compensation, calculate the resistivity, and shows the results on the display of the instrument.
