- Borrow portable hard drive.
- Clean up sticker residue and magic marker writing.
Remove LVDT modules; identify screws.
Check that all in-air cables are labeled.
- If possible, reroute cable to eliminate need for fifth feedthrough.
Debug all electronics, especially actuation.
- Measure IP period; adjust ballast mass.
Calibrate all LVDTs. BF, SF, PI-GAS, PI-H1, PI-H2, PI-H3
- Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs.
- Set all EQ stops to TBD clearance.
