Jim, Mitchell & Hugh
Jim went in chamber to assist Betsy with Baffle hanging while Mitchell & I did the final dressing of the sensor cables. We followed protocol (T1200193) to insure consistent grounding of the GS13 seismometers. The sensor cables where then checked with the emulator to confirm good & right cables. All checked out and then were plugged in. All sensors now functional.
Next we checked the zeros on the HEPI Load Cells, all below 20lbs. Continued then with HEPI loading after the horizontal locks were pulled back. All corners now floating. We are ready to level and elevate the ISI Optical Table in prep for IAS.
