The Forward Calorimeter (FoCal) prototype, which is a digital pixel sensor calorime- ter, is made up of absorbing material and active volumes. In the active volumes three different types of chips have been implemented which differ in sensitivity. The differ- ences in sensitivity have been corrected by carrying out a calibration procedure. The calibration procedure is applied to SPS measurements with particle beams of respec- tively an energy E of 30, 50, 100 and 244 GeV. As a result 96 calibration factors are attained. The calibration factors are applied to the raw data to obtain calibrated longitudinal hit profiles.
