When Exposure section is changed, make sure to create new calibration data by
processing Offset calibration and Gain calibration to get optimized images.

Pre Exposure section can be used when the time delays until the generator receives EXP-
OK signal from the detector and generates X-ray. Although Pre Exposure section is set as
0㎳ normally, it is recommended to measure and set the actual delay time of X-ray
generation to achieve the best performance of the detector. The detector sends EXP_OK
signal to the generator, then acquires X-ray after the setting time in Pre Exposure
section.

EXP OK Delay section is the delayed time between the detection time of exposure
request signal (EXP_REQ) from the X-ray generator and the time before sending exposure
respond signal (EXP_OK) to the X-ray generator. Some X-ray generators need time to
prepare detecting EXP_OK signal after sending EXP_REQ signal. This time is determined
according to the specifications of X-ray generator.

Debounce_DR is used for removing the trigger signal due to external noise when the
exposure mode is set as DR Trigger. If the value is set to less than 3㎳, the detector may
acquire undesirable images.

Debounce_AED is used for removing trigger signals due to external noise when the
exposure mode is set as AED. If the Debounce_AED value is set longer than the X-ray
exposure time, the detector cannot acquire images. If unwanted images are acquired
without X-ray exposure while the equipment is operated, set Debounce_AED with 1㎳
increments. However, we recommend you not to set the value more than 10㎳.

Gain Type
You can select the Gain Type to adjust sensitivity of the detector for acquiring X-ray images with desired
brightness according to the specifications of X-ray generator or the object type.
