Description
Return outgoingStep = vertexPotential-startPotential and returnStep = endPotential-vertexPotential.
Electrochemical potentials require a common reference electrode, unit and sign convention. Endpoint differences and scan partitions are record operations; changing the reference scale or correcting drift needs explicit supplied offsets.
Return outgoingStep = vertexPotential-startPotential and returnStep = endPotential-vertexPotential.
When to use this tool
Use Sweep Vertex Potential Gap when checking a supplied potential reference or scan-boundary convention.
How to use the tool and how it works
- Enter startPotential, vertexPotential, endPotential. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read outgoingStep, returnStep, closes. Inspect closes before interpreting the associated values.
Return outgoingStep = vertexPotential-startPotential and returnStep = endPotential-vertexPotential. closes is true only for exact startPotential === endPotential.1

}Limitations and assumptions
- Use one potential unit and reference scale. These signed endpoint steps do not infer scan rate, duration, measured hysteresis or closure within a tolerance.
- 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
Use calibrated references and full recorded waveforms when drift, reversal detection, peak fitting or experimental interpretation matters.
