Abstract : A program of investigating possible non-linearity and periodical response errors of LaCoste and Romberg gravity meters over the European Calibration Line (ECL) is presented. Gravity measurements were taken at 147 gravity stations on the ECL, extending from Catania, Sicily to Bodo, Norway. Conversion factors, to correct the manufacturer's calibration tables for non-linearity, were obtained by performing a least squares adjustment on a comparison of gravity meter values with adopted gravity values at eight major stations on the ECL. The report also shows comparisons between the three gravity meters which indicate that the final results, after a correction for non-linearity, are affected by long period variations in meter response. No short period variations were detected.
