Electrode Reference Scale Potential Shift Tool

Convert electrode potentials using explicit reference offsets relative to the same common scale and an additive junction correction.

Description

Return targetPotential = measuredPotential+sourceReferenceVsCommon-targetReferenceVsCommon+junctionCorrection.

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 targetPotential = measuredPotential+sourceReferenceVsCommon-targetReferenceVsCommon+junctionCorrection.

When to use this tool

Use Electrode Reference Scale Potential Shift when checking a supplied potential reference or scan-boundary convention.

How to use the tool and how it works

  1. Enter measuredPotential, sourceReferenceVsCommon, targetReferenceVsCommon, junctionCorrection. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read targetPotential. Use the output convention below.

Return targetPotential = measuredPotential+sourceReferenceVsCommon-targetReferenceVsCommon+junctionCorrection. All potentials share one unit and the two reference offsets use the same common reference.1

Limitations and assumptions

  • Junction correction is added under this convention. Reference values, temperature dependence and liquid-junction behavior are supplied rather than determined.
  • 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.
