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 (à 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°.
