Detailed Description

The following embodiments of the present invention are given, and it should be noted that the present invention is not limited to the following embodiments, and all the equivalent transformations made on the basis of the technical solution of the present application all fall into the protection scope of the present invention.

In the present invention, unless otherwise specified, the use of directional terms such as "upper" and "lower" generally means that the terms are defined with reference to the drawing plane of the corresponding drawing, and "inner" and "outer" mean that the terms are inner and outer relative to the outline of the corresponding part.

Kelvin Four-wire sensing, also known as Four-terminal sensing (4T sensing), Four-wire sensing or 4-point probe method, is an electrical impedance measurement technique that uses separate current and voltage sensing electrodes to enable more accurate measurements than conventional two-terminal (2T) sensing. Kelvin four wire testing is used for some ohmmeters and impedance analyzers and in the wiring configuration of precision strain gauges and resistance thermometers. And can also be used to measure the sheet resistance of the film.

The kelvin four-wire method is connected with two requirements: for each test point, a stimulation line F and a detection line S are arranged and are strictly separated from each other to form independent loops respectively; at the same time, the S line must be connected to a test loop with very high input impedance, so that the current flowing through the test line S is very small and approximately zero.
