An oscilloscope test showing firing lines that are the same but abnormally high is indicative of an issue with the ignition coil or spark plug.
The high firing lines may be caused by a problem with the spark plug gap, a faulty ignition coil, or a failing spark plug. When the spark plug gap is too large,
it requires a higher voltage to jump the gap and ignite the fuel mixture, resulting in high firing lines on the oscilloscope. A faulty ignition coil may also cause the spark plug to receive too much voltage, resulting in high firing lines.
Finally, a failing spark plug can cause high firing lines due to a lack of proper spark intensity. It is important to diagnose and fix this issue as soon as possible to prevent damage to the engine.

To select the required lighting levels and uniformity, one must determine the method of design (e.g.: illuminance or luminance) and the apply the required levels _________.
a. from suppliers catalogs
b. from IESNA illuminacne or luminance tables
c. from the National Electric Code
d. based on the number of collisons
To select the required lighting levels and uniformity, one must first determine the method of design, whether it is illuminance or luminance, and then apply the required levels based on industry standards.
The most commonly used industry standards for lighting design are found in the Illuminating Engineering Society of North America (IESNA) handbook. The IESNA provides guidelines for both illuminance and luminance levels, which take into consideration factors such as the type of task being performed, the surrounding environment, and the type of lighting fixture being used. It is important to note that while there are standards for lighting levels, there is no one-size-fits-all solution. The specific needs of each project must be taken into account when selecting lighting levels and uniformity. This may include factors such as energy efficiency, safety, and aesthetic considerations.
It is not recommended to select lighting levels based on the number of collisions, as this is not a relevant factor in lighting design. The National Electric Code may provide some guidance on lighting levels, but it is not the primary source for industry standards on lighting design. Ultimately, the best approach is to consult with a lighting professional who can help determine the appropriate lighting levels for your specific project.
