Graeme, Finally I managed to measure three patches (just the primaries), in the same screen position and without moving the colorimeter between measurements both with Toolcrib and Quato iColor. Here are the results ToolCrib iColor R 144.62 75.0 3.71 143.9 74.7 3.7 G 85.52 172.51 23.13 85.4 172.3 23.1 B 35.52 17.02 183.66 35.5 17.0 183.6 Now the question is: is this enough to think the colorimeter is working properly? Since I doubt that, do you know of any command that I can run in ToolCrib shell to test the instrument? As far as I can see, nothing seems to indicate malfunctioning in ToolCrib... Fabrizio
