I have been attempting to make a new curve for Cansen BarytaP 2 and measuring two targets they are both exhibiting the same L* False column error #REF! (Reference dos not exist) on line 52 & 53. Line 54 shows a False error of at least -5.64. Changing those 3 lines I can get Line 54 to -0.02 but not 0. What is causing the same #REF! on two targets? ?
please share screenshots and a .zip of the measurement file
