Examples
Try the starting example
- Measured coupler heights (millimetres)
- 8,9,10
- Target height (millimetres)
- 9
- Allowed deviation (millimetres)
- 0.5
- Adjustment to target by coupler (millimetres, JSON)
- [1,0,-1]
- Outside-band coupler numbers (JSON)
- [1,3]
Try another scenario
- Measured coupler heights (millimetres)
- 8.5,9,10.5
- Target height (millimetres)
- 9.5
- Allowed deviation (millimetres)
- 0.25
- Adjustment to target by coupler (millimetres, JSON)
- [1,0.5,-1]
- Outside-band coupler numbers (JSON)
- [1,2,3]
Calculation method
Calculation method
Adjustment to target by coupler (millimetres, JSON)
Target−measured height; positive means raise.
Outside-band coupler numbers (JSON)
Flag abs(measured−target)>allowed deviation.
Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Compare measurements with a user-supplied target band, without adopting any model railway standard. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. All numeric values must be finite. Lists contain at most 100 records; required lists must be nonempty. Rates, probabilities and fractions are entered as fractions, not percentages; fractions must be between 0 and 1. Use a single consistent user-selected currency for all amounts; no exchange-rate conversion.
