Repeatability
1
From any A0 point position, move a certain angle.
Make this point the A1 point. Move the same
distance in reverse as you moved from the A0
point. Measure the stop position P1 with the
measuring instrument.
2
From the P1 point, repeat the same operations as in 1 and measure the P2 point.
3
Repeat the same operations 7 times.
4
Take one half the value of the maximum value
minus the minimum value for the measured
values P1 through P7 and add the ± sign to give
the repeatability.
The "repeatability" is shown in the table below:
