INTRODUCTION
The equipment mod. AT24/EV is one of the modules of the System of Interactive Practical Electronics for Autotronics and it enables to develop the necessary knowledge for the study of
electric and electronic systems used in modern cars.
The lessons included in this module can be developed in:
- Standard mode: using the switches of the equipment and consulting the handbook;
- Computerized mode: the interactive software version of the handbook - SW-D-AT24/EV - interfaced to the module via Control Unit SIS3-U/EV, is used. This software inserts circuit
variations and faults automatically enabling the development of lessons even without teacher’s assistance.
 
AT24/EV
This module enables the theoretical and practical study of the components used in the electronic control systems of vehicle air conditioning.
