We see the colors now. The contour lines still do not seem correct. I have recalibrated numerous times but still do not get good results with the contour lines. I have tried being very precise by putting the calibration target on a roll of tape and aligning it exactly with the white crosshairs. I have noticed that after going through a calibration cycle that the red crosshairs are so-so with matching the target; maybe 1 to 5 cm off. How can I get better results?
