When does the inspector check the calibration of a tint meter?

The calibration of a tint meter is checked before every use to ensure accurate measurements of window tint. This is crucial because even slight inaccuracies in the meter can lead to noncompliance with safety regulations regarding tint levels. By verifying calibration before each use, inspectors can maintain reliability in their measurements and uphold consistency across inspections. Ensuring the tint meter is properly calibrated helps to prevent potential legal issues and contributes to road safety by adhering to set standards for visibility through tinted windows. Regular calibration before use is a best practice in vehicle safety inspections to achieve precise and trustworthy results.
