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?
