Calibration procedure


5.3 Calibration steps

After having summarized the calibration workflow in previous section, the calibration steps are given here:
  1. Move 3MA-X8-Trolley to OK-area of reference sample.
  2. Calibrate at least 10 points per channel as OK (green cloud).
  3. Move trolley and check material based signal variation.
  4. If material based signal variation is too high, system will inform user/supervisor/expert,update calibration by calibrating further at least 10 points.
  5. Move trolley to NOK-area of reference sample.
  6. Calibrate NOK-area (red cloud) and balance database (Number of NOK data has to be atleast 10 % of number of OK data).
> 3MA-X8 system is ready now.

iMaterial based signal variation could lead to higher calibration effort in the beginning.
