rotation of the automatic and mechanical disk. On the back panel there is a 
connector for connecting to the power supply network. 
Setting parameters and making measurements is provided by a 
microprocessor-based measuring system, which is installed inside the monoblock. 
The main ele-ment of the training stand is a microprocessor, the database of which 
stores information about all the measurements and parameters of the experi-ment. 
The installation is made in the form of a complete unit that does not require user 
intervention during operation and consists of several units combined into a single 
module. The demonstration stand is controlled using the control buttons. 
The training laboratory stand is equipped with a complete methodological 
manual, including the theoretical part and the experimental part (the order of 
accomplish-ment), a disk with software, including methodological materials for 
performing laboratory work. Technical characteristics of the training laboratory 
stand: supply voltage 220 Volts, power 50 Watts, weight 2 kg, warranty service for 
5 years. The measurement results obtained with the help of an educational 
laboratory stand are shown below in Table 1.

Along with the consolidation of theoretical knowledge and primary skills of 
experimental observations, the laboratory stand is designed to form the creative 
thinking of students. But its main difference is that it is possible to show physical 
phenomena with the features of their manifestation. 
In the educational laboratory stand, elements of microelectronics are used, 
which allows automatic control of the demonstration experiment, this on the one 
hand increases the interest of students, on the other hand, there is an opportunity to 
familiarize them with the element base of modern electronics, while raising the 
technical level of students ' readiness.
