Determine/characterize apparent offsets in PT readings from actual pressures. #20

Symptom

Despite an apparent high-fidelity calibration done with #10, during Leak Checks and Cold Flow operations completed on 10/29/2022, we seem to be experiencing at least a 20-30 PSI offset from actual values for many of our 1k PTs. This is pretty critical, as we desire to have high-confidence in our PT readings during tests/Hotfire (and Launch) operations and during post-test analysis, even for this small of a granularity.

Plan of Action

Speak with Propulsion and determine possible ways of identifying the source of this offset (or at least determining a means of addressing it BEFORE collecting more data with the DAQ system) to ensure we retain high-confidence in our system's capabilities.

@harrisonCassar to write up potential root cause for this.
