With Hirata-san.

We fixed problems with BF Damper LVDT cables:

• BF-H3,
  • Place: P2-3
  • Pins: 1,6
  • Symptom: the resistance was 21.6 Ohm, which is higher than expected.
  • Solution: We identified the problem was at the pins of the white extension cable connected directly to the LVDT.  When we moved it, the resistance changed by relatively large amounts. Hirata-san removed the problematic pins, put new ones and the resistance became stable with a value of 11.46 Ohm.
• BF-V3
  • Place: P2-1
  • Pins: 1,6
  • Symptom: the resistance was 14.1 Ohm, which is slighly higher than the expected ~ 11 Ohm.
  • Solution: We identified a problem in a connector. When we moved it, the resistance changed by non-negligible amounts. Hirata-san removed the problematic pins and put new ones and the resistance became stable. However, its value remained at around 14.13 Ohm. This might not be a problem, but we will watch it in case glitches appear.
