Specification Notes

[1] Zero-based, least-squares, straight line method.
[2] Low frequency response is determined by external signal conditioning electronics.
[3] Mounted on base.
[4] Verified amplitude response during calibration with reduced useful frequency response on the x and y axes due to mounting on a surface other than the base.
[5] Typical.
[6] Accel from structure into sensor base.
[5] Typical.
[7] See PCB Declaration of Conformance PS158 for details.
