How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
a = (R2 − R1) / (M2 − M1); b = R1 − a M1Inputs
| Name | Unit |
|---|---|
| Measured 1 | psi |
| Reference 1 | psi |
| Measured 2 | psi |
| Reference 2 | psi |
Outputs
| Name | Unit |
|---|---|
| Gain a (hero result) | 1 |
| Offset b | psi |
Diagnose
Observations are context. They do not pass or fail a structure. See Diagnose.
| When | Observation | Severity |
|---|---|---|
|Gain a - 1| > 0.05 | Large calibration correction | caution |
Assumptions
- Two distinct measured values are required.
Provenance
- Apply as Corrected = a × Measured + b. Sign is preserved.
