The disadvantage of the device is the inability to output information to a personal computer (PC). [RF patent for utility model No. 144036, IPC A61V 5/053. Mini electropuncture tester, pub. 08/10/2014].

The device closest in technical essence to the developed device is a device for electroacupuncture diagnostics, which contains active and passive electrodes, their conductors, an active electrode housing, an electronic device and an electronic device housing, the active electrode of which is made in the form of a spring-loaded rod, and the spring is electrically connected at one end with the rod, and the other - with the current conductor of the active electrode. The device is intended for electroacupuncture diagnostics in methods that use the measurement of electrical conductivity (currents) or resistance of the skin to electric current when examining acupuncture points [Patent for the invention of the Russian Federation No. 2086176. IPC А61В 5/05, А61Н 39/00, A61N 1/04. Device for electropuncture diagnostics, publ. 08/10/1997].

The disadvantages of the prototype are:

- the absence of a data processing unit, which reduces the efficiency of research;

- the inability to regulate the force of pressing the electrode, which reduces the accuracy of research.

The objective of the invention is to improve the accuracy of measuring the values of the electrical conductivity of human BAT.

The solution to the problem of increasing the accuracy of measuring the electrical conductivity of human BAT is achieved by using a measuring electrode with an adjustable pressing force due to the presence in the design of a micrometer head rigidly connected to a spring-loaded rod.

The technical result is achieved by using a micrometer head in the design of the measuring electrode, during rotation of which to scratches corresponding to pressing forces from 0 to 3.44 N., its movable part changes the pressing force on the electrode by compressing a spring fixed on the rod.
