How to measure the resistivity of a conductive film using a four-point probe (Quickstart Guide)

A four-point probe is a device that's used to measure the sheet resistance of a material. Sheet resistance is a key property of materials, and is often used in material characterisation and during the development of thin-film devices such as solar cells or OLEDs.
This guide teaches you how to measure the sheet resistance of a substrate using the Ossila Four-Point Probe.

Thanks for showing the clear procedure for measurement of ionic conductivity. Can it be used in case of thin film of Alkaline polymer electrolyte membrane for ionic conductivity measurement?
