Car exhaust machine calibration and repair
Test Equipment Preparation and Calibration
• Clean and free of contamination.
• Warm-up test devices to manufacturer's specified operating temperatures.
• Check calibration standards using certified gases with known concentrations of pollutants.
• Perform zero calibration and adjust device if necessary.
• Span calibration introduce calibration gases with known concentrations of target pollutants.
• Check for linearity to ensure accurate measurement across expected pollutant concentrations.
• Document calibration data for compliance with regulations and troubleshooting.
• Perform quality control checks and implement routine maintenance schedules.
• Review and verify calibration results with other instruments or standards.
• Follow a regular calibration schedule recommended by the device manufacturer or regulatory authorities.
