Built-In Spirit Level
Built-in Spirit Level indicates whether an isolation platform includes a bubble level for checking its orientation.
The bubble provides a visual reference for level at its mounting position. It is separate from adjustable feet: a platform may show its orientation without providing a built-in way to change it.

Use the level according to the platform’s setup instructions and check it with the intended equipment load in place where required. Changing the load or support adjustment can change the platform’s position.
A centred bubble does not establish correct loading, equal force at every support or effective vibration isolation. It also does not replace any separate levelling procedure specified by the equipment on top. Check that equipment’s relevant reference surface rather than assuming the platform indicator completes its setup.
