Calculate measured microfarads from capacitor current and voltage under load, then compare with the rated value and tolerance.
Under load, a run capacitor's current and voltage tell you its real capacitance. Compare the result with the rating printed on the can and its tolerance. A value outside tolerance points toward replacement, but check the voltage rating, the wiring and the motor too.
Estimates based on your inputs. Always verify against the manufacturer's data and the codes that apply where you work.
