Because after finishing the IY leak test and health check, we will start the cooling down of the duct shield.
We installed the IY MNV oplev.
Unfortunately, the original IY MNV oplev set was in Toyama University, I temporally moved EY MNV oplev set to IY's.
The calibration factor was measured by
1.49 [cnt/mm], so the calibration factor will be
335.6 [um/cnt]
