9 steps Greyscale Test Chart are used for evaluate hue reproduction characteristics of camera. Those grey modules are displayed in a reverse chronological order based on a grey backgroup （D≈0.75）,the grey scale is log level （gamma=0.45）.Contrast range for this chart is 50:1
| Step | Density | Reflectance in % | Output voltage in % |
| 1 | 0.15 | 71 | 100 |
| 2 | 0.26 | 55 | 88.75 |
| 3 | 0.37 | 42 | 77.5 |
| 4 | 0.51 | 31 | 66.25 |
| 5 | 0.67 | 22 | 55 |
| 6 | 0.85 | 14 | 43.75 |
| 7 | 1.09 | 8 | 32.5 |
| 8 | 1.40 | 4 | 21.25 |
| 9 | 1.85 | 1 | 10 |
Those Density Values is based on the method of BaSO4=0. The area for pure black and pure white is between in the grey scale. The density for black modules is D>2.4(Reflectivity rate>0.5%)，the density for white modules is D>0.09（Reflectivity rate=79%）。
