Advanced Troubleshooting and Board-Level Diagnostics

DIA 190 delves into advanced diagnostic methodologies essential for maintaining complex medical devices. Students will develop proficiency in interpreting detailed electrical and hydraulic schematics, perform precise signal tracing across various circuit boards, and analyze power supply functionality. The curriculum emphasizes isolating faults in control boards, sensor arrays, and communication systems through a structured approach. Participants will gain practical experience with specialized test equipment, learn to apply systematic fault isolation trees, and understand the critical factors influencing repair versus replacement decisions, ensuring optimal system performance and safety. Adherence to service documentation and regulatory standards is a core component of all diagnostic activities.
