Automotive instrument cluster suppliers are challenged with creating systems for testing instrument displays. Numerous types of automotive instrument clusters need to be tested, including large gauges for speed and RPM, smaller gauges for gas and temperature, status indicators for turn signals and system faults, digital and analog odometers, and digital status displays. Instrument clusters must be tested for functionality and interoperability under a variety of of test conditions. New models with unique features are being introduced every year, so test engineers must create test systems that are adaptable to new requirements.
