True DC response X vs.Y axis @ 0 (offset position) The measuring range is limited by sensitivity, offset and supply voltage rails of the device. Offset specified as Voffset = Vout(@0) [V]. +5V supply voltage used in calibration and testing. See proposed connection of SCL1700 in picture 2. Offset calibration error specified as Offset_Calib_error = arcsin(Offset_Calib_error_in_g) [ ], Offset_Calib_error_in_g = {Vout(@0) - 2.5 V} / Vsens [g], Vsens=8.595 V/g. Offset temperature error specified as Offset_Error_@_temp. = arcsin(Offset_Error_@_temp_in_g) [ ], Offset_Error_@_temp_in_g = {Vout @ temp. - Vout @ room temp.} / Vsens [g], Vsens=8.595 V/g. Sensitivity target in calibration 8.595 V/g (a 150 mV/) Sensitivity specified as Vsens = {Vout(@+10) - Vout(@+10)}/(2*sin(10) g) [V/g]. Sensitivity calibration error specified as Sensitivity_calibr_error = {Vsens - Vsens_nom} / Vsens_nom x 100% [%], Vsens_nom = nominal sensitivity.
