CP Series
Version 3.1 – June 2020
For example:
A custom chart will be made for a material ABC using a film brand and type XYZ. The chart will result in a
density of x.x at an FFD of xxx mm.
Using a step wedge made out of the material ABC, 2 exposures are made at an FFD of xxx mm; one at
5mA.min and one at 100mA.min. This is done for each of the kV lines that will be plotted on the custom
chart. The thickness of the material that results in a density of x.x is recorded for each of the developed
films. The result is a table of 2 thicknesses per kV line. The number and range of kV lines that will be
recorded is free to choose within the operating range of the CP SERIES generator.
The table that was found by doing the density measurements on the films can now be recorded in the
PowerBox.
• In the 'Custom charts' menu, choose 'Add new chart'
• Using the alphanumeric keys (7) give your custom chart a name
Specify the lowest kV line that will be plotted. For our example
•
100kV.
Specify the step between each of the kV lines. For our example
•
20kV.
Select 'enter thicknesses' and press the 'OK' button (15).
•
• Now enter the thicknesses of 5mA.min and 100mA.min for each
of the kV lines.
• Select 'continue' and press the 'OK' button to go to the next kV
line.
• Select 'Finish' and press the 'OK' button to complete the entry of
your custom chart.
Your custom chart is now saved and can be recalled when doing an
exposure calculation with the PowerBox's exposure time calculator.

EMORY ACCESS
A set of exposure setting can be stored, recalled or deleted from memory
through the memory access menu of the PowerBox.
Each entry will contain the following set of items:
• Name: Name of the exposure settings set. Can be chosen freely.
kV: kV value
•
• mA: mA value
TP: Exposure time setting
•
• Material: Material type (Fe, Al...)
Film: Used film brand and type
•
Film density: Density on film
•
Thickness: material thickness (the unit can be selected in the 'settings' menu)
•
FFD: Film to Focus Distance (the unit can be selected in the 'settings' menu)
•
