An elevation and leveling adjustment arrangement for accurately locating pressure-to-current transducers, used in monitoring blood pressure during and post surgery, at an appropriate reference point relative to the patient. The pressure-to-current transducers are mounted to a platform or base which also has provided thereon level indicating means and optical means. The optical means in combination with the level indicating means is arranged to indicate when the base is properly leveled and the pressure transducers are at the same elevation as the reference point marked on the patient. In the case where an optical sighting means is employed, the reference point is directly viewable thereby. The platform further includes leveling adjust means which adjustably couples the base to a telescoping elevation adjust means, the latter of which provides fine elevation adjustment of the platform.
