The freshmen of our department for electrical and electronic engineering have assembled digital-multi-meter (DMM) kits since 1999 at Toyota National College of Technology. However, they were not able to understand the theory and mechanics of the DMM's, despite the fact that they were accompanied with good manuals. We developed the instructive dual-slope analog-to-digital (A/D) converter system, which converted circuits arranged on the plane surface of a rack, and we applied the system to the experiment in the lower grade. This paper consists of two sections. Section 1 describes the mechanics, the specifications, and the specific characteristics of the system. Section 2 describes the questionnaire investigation, for which the instructive A/D converter system is useful for students in the lower grades who lack expert knowledge. As a consequence of this experiment and investigation, the students responded well through the experimental approach. Also, the students understanding had increased dramatically.
