2.7 Linearity Corrections
Corrections for linearity in using the Wide Range Filter Pack (37617) are made by taking the apparent
output of the Model 35080B and adding (or subtracting) the value in kV shown on the following curve.
For the greatest accuracy possible, readings should first be corrected for filtration before linearity
corrections are made. For most applications, however, linearity corrections alone may be adequate,
especially if the difference in total filtration from the calibration standard of 2.5 mm Al is small. See
Section 2.6 for information about filtration correction.
Figure2-5. The Wide Range Filter Pack (37617) Linearity Correction Curve. The kVp Correction Value
read from the vertical scale should be added to the Model 35080B kVp Divider reading to
produce the corrected kVp result.
