5.

Determine the highest density minus step
to be used. If there will be unused density
steps, i.e.

–8

, these density steps

must be disabled by setting them to

Select the highest density minus step that
will be used, i.e.

–5

. Use the

+

or

–

buttons

to set the calibration number for that step
to the desired relative density value
(example

50,

this will give approximately

1/2 the density).

For the highest density minus step that will
be used, i.e.

–5

, enter the desired relative

density value (example

50,

this will give

approximately 1/2 the density).

7.

Make an exposure and confirm that the measured mAs is approximately the desired value.

8.

If the measured mAs is not as expected, adjust the calibration number and repeat the previous step.
