Which of the following actions should be avoided during an emissions inspection?

Using inappropriate testing equipment during an emissions inspection can lead to inaccurate results and may ultimately compromise the integrity of the inspection process. Each emissions inspection is dependent on using validated and calibrated equipment that meets regulatory standards. When the correct tools are not employed, the readings obtained can be misleading, which may result in failing to identify a vehicle's failure to meet emissions standards or improperly identifying a compliant vehicle as non-compliant. This misrepresentation can have serious implications for air quality and public health, as well as legal ramifications for the inspector and the facility conducting the inspection. Ensuring appropriate equipment is used is crucial for maintaining the credibility and reliability of the emissions testing procedures.
