Making outline
- Build a reference comparison station using an independent cell/resistance/time realization and null/comparison detector
- Build or acquire each explicit earlier physical input; establish independent references and interfaces.
- Make trials and accept only against the eventual caller specification; record uncertainty and rejected outputs.
What remains unresolved
- Identified requirement; no researched making route or qualified output yet.
- Full inventory, required quantities, process settings, numerical demand and suitability remain open.
