Calibration
21. Verify that the field diameters on the film are within the following tolerances:
Mag Size 9 Image Intensifier Film 12 Image Intensifier Film
Normal 222 MM diameter +/- 4 MM 296 MM diameter +0 MM -4 MM
Mag1 150 MM diameter +0 MM -4 MM 222 MM diameter +0 MM -4 MM
Mag2 130 MM diameter +0 MM -4 MM 150 MM diameter +0 MM -4 MM
22. Record the measured film and Image diameters in a copy of the table below.
23. Subtract the Image and Film diameters for each X & Y axis and enter it as the difference. (Typically about 10 MM, must be
less than 28 MM to be within tolerance 3% SID).
24. Add the X & Y differences for each field size and enter it as the Sum. (Typically about 20 MM, must be less than 36 MM to be
within tolerance 4% SID).
