Yesterday we measured the position and rotation of the HAM 2 and 3 ISIs. The HAM 2 ISI was adjusted by Jim and Greg. Note: the y-axis position measurements are performed with the total station Electronic Distance Meausurement (EDM) feature, which is only accurate to ±2 mm.
The current position errors of both ISIs are as follows:
HAM 2 ISI
-
x-axis position error: -0.4 mm (South)
-
y-axis position error: ~0.0 mm
-
rotation error: 100 µrad CCW
HAM 3 ISI
-
x-axis position error: -0.3 mm (South)
-
y-axis position error: ~ +1.0 mm (West)
-
rotation error: 260 µrad CW
