Note 1.     The measuring range is limited by sensitivity, offset and supply voltage rails of the device.
Note 2.     Offset specified as Voffset = Vout(@0? [V].
Note 3.     +15V supply voltage used in calibration and testing.
Note 4.     See proposed connection of SCL1700 in picture 2.
Note 5.     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=11.46 V/g.
Note 6.     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=11.46 V/g.
Note 7.     Sensitivity target in calibration 11.46 V/g (?200 mV/?
Sensitivity specified as Vsens = {Vout(@+10? - Vout(@+10?}/(2*sin(10? g) [V/g].
Note 8.     Sensitivity calibration error specified as Sensitivity_calibr_error = {Vsens - Vsens_nom} / Vsens_nom x 100% [%],
Vsens_nom = nominal sensitivity.
Note 9.     Sensitivity temperature error specified as
Sensitivity_temp_error = {Vsens @ temp Vsens @ room temp} / Vsens @ room temp} x 100% [%].
Note 10.    From best fit sine-function to output through 10?and +10?
