How everything started…

Universal Component Tester Apprentices Project image

For the first time in the course of the third year of professional training, we weren’t only offered project-oriented training, but we were also given the opportunity to lead an interdisciplinary project. We could choose between a chasing light or a versatile component tester.

When we got the circuits, I was totally fascinated by the usefulness of such a component tester. That made me become a perfectionist; I wanted to construct the perfect product from this terrific circuit. The planning and collecting of ideas started in the first semester, and I had the feeling that my intentions could turn out highly time-consuming. Back at Kapsch Components, I reported my ambitious project which we had started in school. Of course, I asked our excellent prototype construction team for help with electronic and mechanic issues. I realized quickly that my ideas were good, but partly not feasible, so I had to go back to the drawing board. This time, however, with expert support by the KCO Prototyping department and professional software. I was going to replace the original housing of curved aluminum sheets with a shaped aluminum block. I was very pleased with that, because I could learn how to work with the software AutoCAD, how to program CNC and come to a few additional mechanical conclusions. After building the housing, I started designing the electronics, and because I didn’t want it to be too easy, I designed two plates. One with wired components (as the school demanded) and one with SMD components, to prove my skills, which was very welcomed in school. After the practical training in the KCO, I started manufacturing the plates in the second block back in school. I finalized the installation with the finished plate, which I never had to adjust before. When finally everything fit my ideas, I could present a great finished product along with 75 pages of documentation. This, of course, highly impressed my teachers.

The Universal Component Tester project:

The Universal Component Tester is a universally applicable measuring device for component testing. It has a large 16x2 LCD display with blue backlight, which issues the detected components. The evaluation is done by a programmable micro-controller (ATMEGA 8), which takes all measurements and sends the data to the display. Optionally, 2x3-pole adapter cables can be connected to the tester, which can be used as desired, depending on the method of measurement. It comes in a mini-hook and a precision measuring tip version. Usually, the measurement takes about two seconds, with bigger condensers it could possibly take up to one minute.

Automatic detection of:

  • NPN and PNP transistors
  • Diodes
  • Thyristors
  • Triacs
  • Resistors
  • Condensers
