Description
Label potential-scan direction from two supplied potentials.
Electrochemical quantities require explicit electrode references, current sign, area definition and time basis. Geometric area differs from active-area conventions, charge differs from charge equivalents, and a logarithmic current coordinate needs a same-unit reference magnitude. Local sign changes and coordinate terms do not fit kinetics or establish a valid experiment.
Label potential-scan direction from two supplied potentials.
When to use this tool
Use Voltammogram Scan Direction Tag when you already have previousPotential, currentPotential and need to label potential-scan direction from two supplied potentials.
How to use the tool and how it works
- Enter previousPotential, currentPotential. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read direction, increment. Use the output convention below.
Increment=currentPotential-previousPotential; choose increasing-potential, decreasing-potential or unchanged by its sign.1

}Limitations and assumptions
- Potentials must share one unit and reference. Current direction, oxidation/reduction, a complete scan or physical instrument state is not inferred.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect calibrated instrument records, reference-electrode details, area definitions and the complete experiment before interpreting results. Use the full electrochemical model and verified operating conditions when a local current, charge, sweep or impedance-representation term cannot answer the scientific question.
