Appendix A: Quad Pressure Calibration
The purpose of this calibration is to fine-tune all four pressure measurements so they
read the same when exposed to the atmosphere. This will allow the small pressure dif-
ferences that occur in the apparatus to be measured more accurately.
Conduct this procedure with all four pressure ports exposed to the same pressure.
