AGFA DRY 3.4 User Manual page 91

The displayed values (that have to be monitored) represent the following
steps on the test film:
Operating Level
Low density the density value of the Low
Mid density
High density the density value of the High
5. Record the density levels on Chart 1 ('Determination of Operating Levels').
6. Press the Confirm key to return to the main menu.
7. Repeat steps 1 through 6 once a day for five consecutive days, as indicated
on the Chart 1.
8. Calculate the average value of the densities from the five images. These
values represent operating levels or aim values, for each density.
9. Record the respective aim (average) values as the 'Operating levels' on
Charts 2a and 2b ('Daily Density Control Chart').
The calculated 'Operating levels' should be as follows:
Operating Level Value (Macbeth units) (according IEC 1223-2-4 or
Low density
Mid density
High density
10. These charts will be used for the daily quality test.

WARNING:
If the mid density value does not meet or exceeds the
recommended values, the cause must be found and the
problem solved before any further clinical films can be
