XT V 160 X-ray System
5.2 Condition the source
Background
Conditioning of the X-ray source is required to achieve a stable operating voltage, and hence
a steady image. The conditioning process needs to be done on a regular basis to ensure that
the X-ray source will perform as required. If the X-ray source is not conditioned regularly,
then when a high kV is demanded, it is likely that the X-rays will switch off automatically and
the requested kV will not be achieved.
An auto-conditioning schedule should be determined according to the demands on the
system. Auto-conditioning is also required after the filament has been changed or if the
generation of X-rays becomes unstable..
You can also auto-condition the source as part of regular filament
adjustment or filament recalibration.
Procedure
To condition the source, follow these steps:
1. In Inspect-X, click Setup to select the setup controls.
2. In the X-rays panel, under Auto-condition, set the required maximum kV.
You can either type a number into the Requested field or press the 'change' buttons until
the required kV value is displayed.
Auto-conditioning set 0 µA internally within the software.
3. Click Auto-condition.
The system will automatically ramp up to the specified voltage. This may take some time,
depending on how long the system has been idle.
The X-ray status (in the X-ray zone in the bottom right corner of the Inspect-X window)
shows that auto-conditioning is taking place.
During auto-conditioning, the X-rays switch on and off automatically until the source
stabilises at the specified maximum kV. The amount of time that the source is stable at
the required kV displays on the screen for information.
4. When you are satisfied with the results and the source has stabilised at the required kV,
click Stop.
