What does the RPM Pickup Screen display?

The RPM Pickup Screen displays the current vehicle RPM status, which is crucial for emissions testing. This screen provides real-time information about the engine's revolutions per minute, allowing inspectors to monitor how the vehicle's engine is running at any given moment during the testing process. Understanding the current RPM is essential for ensuring the vehicle operates within acceptable limits, ultimately influencing emissions outputs.

Real-time RPM data is vital for accurate emissions measurements because specific RPM thresholds may be necessary for certain tests or procedures. Knowing the exact RPM helps inspectors assess whether the vehicle meets required emissions standards and allows for proper adjustments and evaluations during the inspection.

In contrast, the other options discuss averages, ranges for various vehicles, or instructions, which, while potentially useful in different contexts, do not pertain to the immediate function of the RPM Pickup Screen during an emissions test.
