5. A change in the AC line voltage affects the peak voltage applied to the X Ray tube and the value of high voltage significantly affects the spectrum of the radiation that ultimately affects the optical density of the imaging media The purpose of the X ray Control timer correction is to obtain the same nominal optical density on the imaging media independent of the AC line voltage variations from 108 132 Volts The automatic correction of the exposure time works as follows The internal voltage measuring circuit in the X ray Control Timer continuously monitors the AC line voltage When the user selects the desired exposure time and presses the X ray Exposure button the exposure time will be automatically adjusted based upon the measured AC line voltage The corrected actual exposure time will be displayed until the X ray Exposure button is released NOTE Electromagnetic interference between the equipment and other devices can occur Do not use the equipment in close conjunction with sensitive devices or devices creating high electromagnetic disturbances TECHNICAL SPECIFICATIONS The corrected exposure is calculated applying a correction factor to the selected exposure time based on an empirical law that correlates the dose with the high voltage peak and consequently with the line voltage The qualitative relationship between the multiplying factor and the line voltage is shown in the following graph EXPOSURE TIME CORRECTION FACTORS VS
