question
which of the following is not an example of emissions testing equipment?
a. chassis dynamometer
b. gas analyzer
c. scan tool
d. dmm/test light

Explanation:

• A chassis dynamometer is used to test vehicle performance (like power and torque) under load, not specifically emissions.
• A gas analyzer measures pollutants in exhaust gases (e.g., CO, HC, NOx), which is directly related to emissions testing.
• A scan tool can access and analyze data related to emission - control systems (e.g., check for diagnostic trouble codes related to emissions).
• While a DMM (Digital Multimeter) and test light are basic electrical diagnostic tools, they are not primarily used for emissions testing.

Answer:

a. Chassis dynamometer
