Absolute measurement accuracy
The following equations are used to calculate absolute accuracy.
Absolute accuracy Aa of |Z|, |Y|, L, C, R, X, G, B (L, C, X, and B accuracies apply
when Dx ≤ 0.1, R and G accuracies apply when Qx ≤ 0.1 )
Equation 1. Aa = Ae + Acal
Aa Absolute accuracy (% of reading value)
Ae Relative accuracy (% of reading value)
Acal Calibration accuracy (%)
where G accuracy is applied only to G-B measurements.
D accuracy (when Dx ≤ 0.1)
Equation 2. De + θcal
Dx Measured D value
De Relative accuracy of D
θcal Calibration accuracy of θ (radian)
Q accuracy (When Qx × Da < 1)
Equation 3.
±
(Qx 2 × Da)
(1 Qx × Da)
Qx Measured Q value
Da Absolute accuracy of D
θ accuracy
Equation 4. θe + θcal
θe Relative accuracy of θ (degree)
θcal Calibration accuracy of θ (degree)
