WebThe precession angular velocity is ωP = dφ dt ω P = d φ d t and from this equation we see that. ωP = rMg Iω. ω P = r M g I ω. In this derivation, we assumed that ωP ≪ ω, ω P ≪ ω, that is, that the precession angular velocity is much less than the angular velocity of the gyroscope disk. WebPrecision levels vary depending on the analyte and the method. Generally, electrolytes and creatinine have very low CV% indicating very good precision. Enzymes and immunoassays typically have higher CV%. One other rule of thumb is that a method's CV or SD should be <1/8th of the reference range width.
