投照时,由于操纵X线机失误而造成废片的原因是很多的。用KE-200X线机作滤线器摄影时,常见三种情况会产生废片:1.滤线器尚未上弦,暗合已装入滤线器下的片托(胶片屉)内,控制台技术开关(TBS)还在计时器档(T端)时按曝光按钮。在滤线器不运动的情况下曝光;2.暗合已装入滤线器下的片托内,滤线器虽已上弦,但控制台技术开关仍在计时器档时按曝光按钮,滤线栅仍未动作而曝光;3.使用滤线器按正常步骤摄片后,暗合尚未取出,
There are a lot of reasons for throwing movies off due to mistakes in handling X-ray machines. When the KE-200X is used as a filter, three types of waste will occur: 1. The filter has not been wound, and it fits inside the tray (film tray) under the filter, console technology The switch (TBS) also presses the exposure button while in the timer (T side). Exposure while the threader is not moving; 2. Coinciding with the tray underneath the threader, although the threader is wound, but the console technology switch is still pressing the exposure button in the timer setting. The gate is still not exposed and exposed; 3. After using the filter to take the normal procedure, the coincidence has not been taken out.
