Do ambient light, vibration and temperature affect measurement results?

The effects are real and are among the most common on-site issues in precision measurement, so they should be addressed at the design stage. Ambient light: use an enclosed measuring chamber or light shield, keeping direct sunlight and flickering sources out of the field of view. Vibration: physically isolate the machine from presses and compressors, using a vibration-isolated table or separate foundation if necessary, because vibration directly destabilizes edge extraction. Temperature: both part and machine expand thermally, and a 1°C change can produce observable dimensional drift over hundreds of millimetres, so a temperature-controlled shop or temperature-compensated calibration is recommended. The installation conditions checklist states the environmental requirements for each model.
