Specification Notes

[1] Conversion Factor 1g = 9.81 m/s².
[2] 1Hz = 60 cpm (cycles per minute).
[3] Zero-based, least-squares, straight line method.
[4] The high frequency tolerance is accurate within ±10% of the specified frequency.
[5] Typical.
[6] 1/4-28 has no equivalent in S.I. units.
[7] See PCB Declaration of Conformance PS023 for details.
