If a leak is not detected what should the needle for the pellet indicator be at?

When assessing a leak with the pellet indicator, if there is no leak detected, the needle should reflect that through its position. Specifically, if the pellet indicator is functioning correctly, it should indicate that there is either no flow or a very minimal flow, which is represented by the needle dropping to the bottom. This is crucial for understanding the integrity of the engine's systems. A needle position at the bottom of the gauge confirms that the system is sealed and not allowing any air or fluid to escape, which would occur in the event of a leak.

In contrast, if the needle appears in the middle or remains at the top, it would suggest that there is either some degree of flow or pressure that is not typical of a leak-free scenario. When analyzing indicators like these, ensuring that readings accurately represent the physical conditions of the engine is essential for diagnostics and performance assessments.
