SUGGESTED PULSE SETTINGS
The chart below lists approximate pulses necessary to penetrate various materials. Settings vary greatly depend-
ing on imaging system used. Refer to imaging system instructions for more information.
The following is true when using film or digital systems that generate a positive image. If the radiograph is too
dark, the film is underexposed. If the radiograph is too light the film is overexposed. Underexposure can be cor-
rected by increasing the number of pulses and/or decreasing the distance between the imaging medium and the
XRS4. Overexposure can be corrected by reducing the number of pulses and/or increasing the distance between
the imaging medium and XRS4.
