Description
Signed supplied bench force calibration against an explicit reference without therapeutic recommendations.
Movement research distinguishes elapsed time, active time, cycle phase, measured force, and assessment-score conventions. Normalizing or remapping these quantities can help compare records when their units and definitions agree. A local arithmetic term does not by itself validate a functional assessment or an exercise program.
Signed supplied bench force calibration against an explicit reference without therapeutic recommendations.
When to use this tool
Use Force Sensor Zero Residual when you need this motion, timing, force, annotation, or score-mapping component for supplied research records.
How to use the tool and how it works
- Enter signal, suppliedZero, suppliedGain, referenceForce. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read correctedForce, residual. Use the output convention below.
For positive suppliedGain return correctedForce=(signal-suppliedZero)*suppliedGain and residual=correctedForce-referenceForce.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| signal | Signal | Required. Finite number. |
| suppliedZero | Supplied Zero | Required. Finite number. |
| suppliedGain | Supplied Gain | Required. Finite number; strictly above 0. |
| referenceForce | Reference Force | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| correctedForce | Corrected Force | Required. Finite number. |
| residual | Signed observed-minus-implied discrepancy under the stated formula. | Required. Finite number. |

}Limitations and assumptions
- Gain must convert the signal difference into the reference force unit. Calibration values are trusted; sensor linearity, drift, and clinical significance are not checked.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use the intended assessment or motion-analysis protocol with verified timing, units, and event annotations. A complete interpretation needs the relevant measurement properties and task context beyond this local calculation.
