What should be done if the differences in readings during the pressure control test exceed the allowable percentage?

If the differences in readings during the pressure control test exceed the allowable percentage, adjusting the equipment and retesting is crucial for ensuring accuracy and safety. This approach confirms that any discrepancies are addressed before making operational decisions. Each test is essential for verifying that the system will perform correctly under actual conditions.

Continuing with the test without making necessary adjustments could lead to incorrect conclusions about the system's pressure capabilities. Notifying the supervisor may be warranted depending on protocols, but without first addressing the inconsistency, there may be no actionable information to relay. Documenting the data for future reference is a good practice, but it does not resolve the immediate issue of exceeding allowable limits. Therefore, the most appropriate step to take is to make the necessary adjustments and retest, ensuring that all equipment operates within the established specifications.
