Description
Compare a current magnitude with a supplied potentiostat range.
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.
Compare a current magnitude with a supplied potentiostat range.
When to use this tool
Use Potentiostat Over Range Flag when you already have measuredCurrentAmperes, selectedRangeAmperes and need to compare a current magnitude with a supplied potentiostat range.
How to use the tool and how it works
- Enter measuredCurrentAmperes, selectedRangeAmperes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read overRange, absoluteRangeFraction. Inspect overRange before interpreting the associated values.
Require selectedRangeAmperes>0; return abs(current)>range and abs(current)/range.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| measuredCurrentAmperes | Measured Current Amperes | Required. Finite number. |
| selectedRangeAmperes | Selected Range Amperes | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| overRange | Strict magnitude>range comparison; equality is not over range. | Required. Boolean. |
| absoluteRangeFraction | Absolute Range Fraction | Required. Finite number. |

}Limitations and assumptions
- Equality is not over range. No instrument is read, clipping verified, selected range approved or measurement uncertainty assessed.
- 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.
