Comment to ETMY F2 GAS signals got strange in this morning (29603)

[Takahashi, Washimi]

We checked the resistance of the F2 LVDT coils at the feedthrough flange again. Though the resistance of the actuator coil (3-8pin) was large at 1kHz the last time, it was similar to the resistance before O4a in DC.

  Befor O4a This time
1-6 203.0Ω 209.5Ω
2-7 82.3Ω 87.3Ω
3-8 118Ω 122.4Ω
4-9 NC NC
