NOTES: [1] Constant current should be reduced to ≤6 mA when operating sensor above 250°F. [2] Typical. [3] Not recommended for use with magnetic mounting base. [4] Conversion Factor 1g = 9.81 m/s². [5] The high frequency tolerance is accurate within ±10% of the specified frequency. [6] Zero-based, least-squares, straight line method. [7] 1/4-28 has no equivalent in S.I. units.
