Countless options exist for CBT training in electronics testing. The overall goal is for a student to design and test a circuit on the computer screen. By doing so, she gains a new understanding of electricity. If the design is wrong, components will undergo a virtual failure mode. Another software product, called V4 Troubleshooting Electrical Circuits (TEC) is a troubleshooting simulator that creates faults. Students find and fix faults in the circuitry as they are presented.
CBT programs offer virtual test equipment such as voltmeters. Students set the control ranges, and move the test probes around to different part of the circuit. The meter has a virtual display, and students record the readings.
Programmable Logic Controllers (PLCs) are heavily used in industrial robotics and automation systems. PLC trainers allow students to virtually program and test a PLC. If they program incorrectly, the automation machinery may virtually crash. Because it is a simulation, they can go back and fix their errors. In the real world, of course, if a machine crashed it would results in thousands of dollars in damages. For this reason, students are encouraged to train on virtual simulators first. One such simulator is the RSlogix program from the Business Industrial Network.
CBT circuit testing is useful, but never should be entirely substituted for the real thing. If you are entering the field of electricity professionally, bear in mind the real world has real components -- with real electricity flowing through them. For example, a professional electrician may be asked to test a 480 volt 200 amp bus line for continuity. CBT is a primer for the real world, but not equal to it. If you are using CBT for personal knowledge only, bear in mind that it takes more real training to know how to use test equipment safely. Do not attempt to test live circuits without the proper training.
