From all suitable ISOPHOT archieve data, the differential instrumental effects for P- and C-detectors were reviewed. In general each ISOPHOT observation comprised a sky and a heated Fine Calibration Source (FCS) measurement, obtained on observing and calibration mode respectively. Analysis showed that the by-passing sky light increases the FCS signal level and consequently contributed to overestimate the responsivity.
