    Specification Notes

    [1] Conversion Factor 1g = 9.81 m/s².
    [2] Zero-based, least-squares, straight line method.
    [3] The high frequency tolerance is accurate within ±10% of the specified frequency.
    [4] Typical.
    [5] 1/4-28 has no equivalent in S.I. units.
    [6] See PCB Declaration of Conformance PS023 for details (however, see PCB Declaration of Conformity PS061 for optional ATEX models (i.e., those optional models including "EX" within the model number)).
