More than just a continuity beeper
The kit CONTITEST 4000 introduces pupils and apprentices to electronics, based on a practical and meaningful concept. Hence, first contacts with electronic components (such as resistors, capacitors and transistors) will lead to an impressive experience of success when the students assemble the kit. In addition to building the tester, two additional aspects are important:

1. The working continuity tester often accompanies a person for many years, as an extremely important and meaningful tool. This holds true whether the person regularly tests components (such as incandescent bulbs, fuses, switches or electronic components) in a professional capacity; or the continuity tester is only occasionally needed for personal use, e.g. to install a car radio.

Even in our high-tech era, a continuity tester remains indispensible

2. The aspect of conveying knowledge should not be neglected. Our detailed curriculum explains how to deal with parts used to assemble equipment. In addition, the lessons provide background theory on how the components (such as flip-flops, amplifiers and the tester's protective circuit) function, resulting in very usable knowledge about basic circuits.
CONTITEST 4000 indicates continuity optically with a red LED and acoustically via a speaker. However, the speaker can be disabled with a switch.
