Description
Return difference = measuredPotential-suppliedReferencePotential and sign = Math.sign(difference), using one compatible potential unit and reference basis.
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 difference = measuredPotential-suppliedReferencePotential and sign = Math.sign(difference), using one compatible potential unit and reference basis.
When to use this tool
Use Reference Electrode Offset Sign when checking a supplied potential reference or scan-boundary convention.
How to use the tool and how it works
- Enter measuredPotential, suppliedReferencePotential. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read difference, sign. Use the output convention below.

}Limitations and assumptions
- Exact equality returns zero; no tolerance, reference-electrode selection or electrochemical significance is 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
Use calibrated references and full recorded waveforms when drift, reversal detection, peak fitting or experimental interpretation matters.
