Figure 3-18. The Detector Select Screen
The ion chamber calibration unit (R/C shown here) includes the radiological measurement unit (R). This is the radiological unit that appears on the Measurement screens.
NOTE
The ion chamber’s calibration unit includes the radiological measurement unit.
If you want radiological units that are not available, use the Customization software (see Section 3.10) to enter a new ICCF with the appropriate units.
The descriptive text should contain enough information to let the operator correctly select an ICCF that is appropriate for the measurement desired, e.g. energy, modality, build up, etc.
3.9.9 Using the AIR DENSITY Button
Pressing the AIR DENSITY button displays the Air Density screen, see Figures
ADC | 760 mmHg |

ADCF = 1.002
Figure 3-19. The Air Density Screen With Air Density Corrections Enabled
To disable the air density correction, advance the “f” cursor to the ADC annunciator at the upper left of the display. With the “f” cursor at this position, pressing the UP and DOWN keys will toggle the air density correction on (ADC) and off (OFF).
