How to confirm ViViTest static head pressure calibration is correct

With the Static Head Compensation de-selected and sensors open to atmosphere, all  pressure tracing should be at zero.

With the Static Head Compensation checked and all transducers still open to atmosphere, confirm that the ventricular tracing is at zero, the atrial tracing is a little bit above zero, and the aortic tracing is a bit above the atrial tracing.

With the Static Head Compensation still selected, open the transducers to the test fluid (and corresponding static pressure head) and confirm that the atrial and aortic tracing rise to the level of the ventricular tracing.
