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