App id: INST-19. Reference version 1.0.
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
error = indication − referenceInputs
| Name | Unit |
|---|---|
| Reference 1 | psi |
| Indication 1 | psi |
| Reference 2 | psi |
| Indication 2 | psi |
| Reference 3 (optional) | psi |
| Indication 3 (optional) | psi |
Outputs
| Name | Unit |
|---|---|
| Maximum absolute error (hero result) | psi |
| Average error | psi |
| Percent of span | % |
| Percent of reading (worst) | % |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Span is max reference minus min reference of the entered points.
Provenance
- Leave point 3 blank for a two-point check. Percent of reading skips a zero reference.
