Which device is typically used to confirm dimensional accuracy after repairs?

• A. A computerized frame measuring system
• B. A speedometer
• C. A digital multimeter
• D. A dynomometer

Answer: (A)

Verifying dimensional accuracy after repairs means checking the vehicle’s frame and body dimensions against the factory specifications to ensure proper alignment and safety. A computerized frame measuring system is designed for this purpose. It uses fixed reference points on the vehicle and measures geometry with precision, then compares those measurements to OEM data in software. The system highlights any deviations and guides technicians on the exact adjustments needed, which helps ensure correct door gaps, panel fit, steering geometry, wheel alignment, and crash performance. Other devices serve different purposes: a speedometer checks vehicle speed, a digital multimeter tests electrical values, and a dynomometer measures engine or drivetrain performance. None of those specifically verify the vehicle’s dimensional accuracy.
