#64AEC/d The density display shows d . In this mode the wanted optical
density for the IQC must be programmed.
– IQC is done with the sensitometer. Flash a film with
the sensitometer and process the film. Select the step
that has the optical density close to 1.00. Program
the O.D. into this mode. Inform the technologist to
follow this step when performing the IQC. Refer to
Operation Instructions, Chapter Integrated Quality
Control test.
– IQC is done by making a test exposure with a
phantom and with the kV selected for IQC (see

into this mode. Refer to Operation Instructions,
Chapter Integrated Quality Control test.
Press kV+
#64AEC/h The density display shows h . In this mode the IQC procedure
and kV are selected:
0 = IQC done with the sensitometer
– 23 - 35 = IQC done by a test film using 23 - 35 kV and
a phantom or 40 mm acrylic. Use Den+/Den- buttons
to select the kV value.
