Why is it necessary to mark the wobble plate before removing the bobble plate from the measuring unit?

Marking the wobble plate before its removal from the measuring unit is essential because it ensures that the wobble plate is reinstalled in the exact position it was originally in. This is crucial as the specific orientation can affect the performance characteristics of the measuring unit. The precise alignment promotes proper functioning and prevents potential issues such as incorrect measurements or mechanical failures that can arise if the wobble plate is not returned to its original position.

While other factors, like manufacturer's instructions or proper placement of components, are important, the main reason truly hinges on the need for exact reassembly to maintain the integrity and functionality of the system.
