RepeatabilityWhen white calibration plate is measured 30 times at 10-sec. intervals after white calibration has been performed:
Spectral reflectance: Standard deviation within 0.05%
Chromaticity: Standard deviation within ΔE*ab 0.005
When black tile (BCRA Series II; reflectance: 1%) is measured 30 times at 10-sec. intervals after white calibration has been performed:
Spectral reflectance:
380 to 740 nm: Standard deviation within 0.02%
360 and 370 nm: Standard deviation within 0.04%
Chromaticity: Standard deviation within ΔE*ab 0.05
Inter-instrument agreement (LAV)Mean ΔE*ab 0.08 (typical) Average for 12 BCRA Series II color tiles
Max. ΔE*ab 0.3 (corresponds to ΔEcmc 0.2) for any of 12 BCRA Series II color tiles compared to values measured with Konica Minolta master body
