A prototype device to calibrate recording Earth tide meters of the TRG-1 variety has been constructed and demonstrated to operate satisfactorily. The calibration is effected by subjecting the gravimeter to an external sinusoidal acceleration of approximately 3 [j.m/s2. The magnitude of the applied acceleration, which is determined from a record of the gravimeter's displacement, is compared directly with the gravimeter's response. The prototype was limited to a driving frequency of 0.01 Hz. Thedoi:10.1098/rsta.1973.0047 fatcat:l53sfstfd5fwfepdyncc4olqpq
