A lab scope is one of the most powerful diagnostic tools in the shop, yet many technicians struggle with setup, connections, and waveform interpretation. This hands-on class helps technicians gain confidence using their lab scope by focusing on practical setup, operation, and diagnostic application.
Key Learning Outcomes
• Configure time, voltage, and trigger settings for accurate captures
• Select the proper probes, adapters, and accessories for any test
• Build test loops and harness connections efficiently
• Use trigger strategies to stabilize waveform displays
• Navigate common ATS, Pico, Snap-on, Fluke, Autel, and Bosch lab scope functions
• Apply lab scope testing to both mechanical and electrical diagnostics
This class is for technicians who want to become more proficient with lab scope setup, waveform capture, and real-world diagnostic interpretation.
-
Many electrical diagnostic procedures still rely on unloaded voltage tests and resistance measurements that provide limited diagnostic value. This hands-on class focuses on practical DVOM testing methods that technicians can immediately apply in the shop, using proven diagnostic strategies developed from real-world experience.
Key Learning Outcomes
• Select the correct DVOM settings, leads, and probes for any measurement
• Identify the most effective tests for sensors and actuators
• Perform loaded circuit voltage drop testing
• Diagnose failed components and circuit faults
• Interpret duty cycle, peak voltage, average voltage, and frequency measurements
• Understand DVOM limitations and avoid common testing mistakes
This class is for technicians of all experience levels looking to strengthen electrical testing skills and improve diagnostic accuracy.
-
Modern electrical diagnostics require more than following flow charts. This class teaches technicians how to use wiring diagrams as part of a disciplined diagnostic process, helping them quickly identify fault categories, eliminate unnecessary testing, and navigate today's increasingly complex electrical systems.
Key Learning Outcomes
• Identify circuit types, including series, parallel, and combination circuits
• Classify electrical faults such as opens, shorts, and high-resistance conditions
• Trace current paths, parallel paths, and enabling paths
• Select the most effective test locations and testing methods
• Determine the best diagnostic tool for each situation
• Reduce diagnostic time by eliminating unnecessary circuit testing
This class is for technicians and diagnosticians who want a more structured and efficient approach to electrical fault isolation and circuit analysis.
-
This class provides a deep dive into diagnosing misfires and low-cylinder-contribution concerns using a structured diagnostic process. Attendees will learn how to quickly narrow potential causes, leverage available data, and reduce unnecessary testing when diagnosing modern driveability complaints.
Key Learning Outcomes
• Differentiate between current and history misfire data and non-misfire relative contribution data
• Distinguish between Fuel Trim-related causes and secondary symptoms
• Identify compression-related faults more efficiently
• Isolate non-compression mechanical failures using a logical diagnostic process
• Analyze modern ignition primary and secondary voltage waveforms
• Build and refine a cause list using real-world diagnostic strategies
This class is for technicians diagnosing customer complaints, driveability concerns, misfires, and performance-related faults on modern vehicles.
