Notes:
1: Full range is defined as "from negative full input acceleration to positive full input acceleration."
2: Nonlinearity is specified as deviation of output referenced to a best fit straight line, independent of misalignment.
3: Output phase angle = -90°
4: Unit Power connections can be easily adapted for operations from single-ended, floating power supplies of 24 to 36 Volts DC.
