Hints
[1] typically,
[2] When using the recommended preload. The sensitivities may change by ± 5% depending on the preload used.
[3] The specified sensitivities apply only when using the supplied bolts.
[4] Zero-based balancing line, determined by the least squares method
[5] The preload should be at least ten times the operating range used on the X and Y axis.
