Abstract
Automated equipment for determining the susceptibility of steels and alloys proposed. The principle of operation of equipment units and their main characteristics are presented. Microprocessor system with AVR microcontrollers from ATMEL for equipment used. The algorithm of the program a microprocessor system for automatic operation of equipment considered. Dependence of the current compensation of the current force field as a text file on your computer equipment can be formed.
