Example: For the Wide Range Filter Pack (37617) (50-150kVp), the Expected CAL kVp is given as 80,
and the Zero offset value is 40 kVp. However, a Model 35080M kVp Divider in CAL mode with this filter
pack inserted is connected to a Model 35050AT Dosimeter, and a kVp of 81.2 is measured. When placed
in an X-ray beam in RUN mode, the Model 35050AT Dosimeter reads 91.5 kVp. The Corrected kVp for
this exposure is calculated from the previous equation.
