How worksheets differ from single calculators
- 1Start with the job intent: hydraulic design, battery and NAC review, water supply, pump selection, or hazard setup.
- 2Use the input matrix to confirm where each value comes from before opening linked calculators.
- 3Run phases in order and keep the QA gates and saved records with the calculation package.
