KELVIN® Troubleshooting Trainers™ are ideal for middle school students and up. When working within the field of electronics, students should know how to troubleshoot, evaluate, and repair electronic circuitry. The KELVIN® Troubleshooting Trainers™ are inexpensive and easy to set-up because they require no wiring or soldering.
Using troubleshooting and problem-solving procedures, KELVIN® Troubleshooting Trainers™ show students how to find a problem on a PC board and then fix it. The trainers were developed to make teaching troubleshooting fast, easy, and effective - with actual electronic equipment, hardware, and pre-wired circuits.
According to the experiments, the teacher inserts a problem into the circuit using DIP switches. By following the circuits and measuring the components, students then isolate the trouble and fix it using problem-solving techniques and by resetting the DIP switches. System concept and student manuals developed by Lou Frenzel.
Set includes all five of KELVIN® Troubleshooting Trainers™ in one complete set! Trainers include AC, DC, Digital, Analog, Communications.
Each assembled trainer includes: pre-wired printed circuit boards (8-1/2 x 11 in.), wall adapter power supply, 3-ring storage binder, working electronic circuits with DIP switches, student lab manuals with experiments and tests, and a teacher's guide with detailed and documented faults.
