NOTES:
[1]	Maximum of 4 mA is recommended at temperatures above 250 °F (121 °C).
[2]	Bias voltage increases with higher constant current.
[3]	Typical.
[4]	Conversion Factor 1g = 9.81 m/s².
[5]	1Hz = 60 cpm (cycles per minute).
[6]	The high frequency tolerance is accurate within ±10% of the specified frequency.
[7]	Zero-based, least-squares, straight line method.
[8]	1/4-28 has no equivalent in S.I. units.
