Abstract
A pressure calibration device can include certain features that allow it to be used with a variety of hydraulic and pneumatic systems. A pressure calibration device can be configured to provide pressure or vacuum, and can have a mode selector for selecting to provide pressure or vacuum. A pressure calibration device can have a volume adjuster configured to modify pressures for hydraulic or pneumatic systems. A pressure calibration device can have a pressure release valve and a bleed valve for adjusting pressure values.
