- Calibrated the LVDT.
- Checked the relative height of the F1 damper.
- Dismounted the pre-isolaotor and the bridge frame from the foothold.
- Implemented the cables between the F1 and the PI.
- Lifted down the EQ stop into the corrugate tube. The top ring sit on the frame lock.
- Adjusted the rotational direction and the center position of the EQ stop.
- Installed the PI into the top chamber.
- Hooked the wires to the receptacles. The filters were suspended from the TF.
- Removed the wire clamp.
