1 Select the molybdenum filter.
2 Install the cassette holder.
3 Check that the semiAuto (A) mode is on. Make a test exposure with
the default kV using 40 mm acrylic. Measure the O.D. If the O.D. is not
correct, increase or decrease the density with Den+/- keys. Repeat
until the O.D. is correct.
4 Mark the density value that produces the right optical density in the
table 2.9 or 2.10 and store the values by programming them in the
program (Pr) mode.
If the film/screen combination and default kV is the same for all channels
a, b and c, the density correction is the same also.
