    KELVIN®'s 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.

    The assembled DC Troubleshooting Trainer™ includes: Pre-Wired Printed Circuit Boards (8-1/2 x 11 in.); Three-Ring Storage Binder; Working Electronic Circuits with DIP Switches; Student Lab Manuals with experiments and tests; and a Teacher's Guide with detailed, documented faults.

    "As a very dedicated and cost conscious electronics instructor, I had previously ordered a single DC trainer from KELVIN® for the purpose of analyzing and testing its classroom potential. Since then, I have ordered one for each student. This trainer has exactly what the textbooks and traditional theory labs are missing; instructor-controlled, fault inserted trainers which challenge the students to learn about procedural troubleshooting and problem- solving habits at the very beginning of their technical training."-David L. Miles, High School Electronics Teacher,Salisbury, Maryland
