NOTES
1
Guaranteed by measurement of initial offset and sensitivity.
2
Alignment error is specified as the angle between the true and
indicated axis of sensitivity.
3
Transverse sensitivity is the algebraic sum of the alignment and
the inherent sensitivity errors.
4
Output settled to within +/-17mg.
