Amplitude Explicit Threshold Screen
Screen measured balance amplitude against explicit caller-supplied minimum and maximum values without applying a universal healthy-degree target.
Description
Amplitude threshold screening compares a measurement with explicit caller bounds.
Amplitude threshold screening compares a measurement with explicit caller bounds. A within-range result is not a stand-alone movement-health verdict.1
Screen measured balance amplitude against explicit caller-supplied minimum and maximum values without applying a universal healthy-degree target.
When to use Amplitude Explicit Threshold Screen
Use this tool to screen measured balance amplitude against explicit caller-supplied minimum and maximum values without applying a universal healthy-degree target.
Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
How to use Amplitude Explicit Threshold Screen and understand its results
- Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
- Enter maximumExpectedAmplitudeDegrees, measuredAmplitudeDegrees, minimumHealthyAmplitudeDegrees using the field table and calculation rules, then run the tool.
- Read amplitudeAboveMaximum, amplitudeBelowMinimum, healthClaimCaution, withinCallerRange. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| maximumExpectedAmplitudeDegrees | Maximum expected amplitude (deg) | number; minimum: 0 | Required |
| measuredAmplitudeDegrees | Measured amplitude (deg) | number; minimum: 0 | Required |
| minimumHealthyAmplitudeDegrees | Minimum caller-defined amplitude (deg) | number; minimum: 0 | Required |
Enter nonnegative measured degrees, positive minimum and strictly greater maximum. Return shortfall/excess, inclusive range flag and health caution.
shortfall=max(0,minimum−value); excess=max(0,value−maximum) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| amplitudeAboveMaximum | Amplitude above caller maximum (deg) | number; minimum: 0 |
| amplitudeBelowMinimum | Amplitude below caller minimum (deg) | number; minimum: 0 |
| healthClaimCaution | Health-claim caution | string |
| withinCallerRange | Within caller amplitude range | boolean |

}
}Limitations and assumptions
No lift angle, winding state, measurement protocol or defect is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Beat Error Symmetry Threshold Screen: Screen two beat-error observations against explicit caller-supplied magnitude and relative-difference limits; this is not a certification decision. For a complementary task, use Isochronism Amplitude Rate Slope Calculator: Measure the endpoint rate change and slope between two caller-supplied amplitude observations; this does not turn a two-point slope into a complete isochronism curve.
