=== TypeBp ===
I will explain using [[https://1drv.ms/b/s!AoQaV1tdsEcUgeNmg0hHZMMSejqOdA?e=AI19Xb|this short presentation]] about the adjustment of PR3 inner wire locating clamps.		 === Type-Bp PR2 ===
This week we inspected and tightened the wires clapms in PR2. We followed the same procedure as in PR3, so I won't write any details here.

 * We removed the IRM side panels and measure the gaps in different places using thickness gauges:
  * Largest gap: 220 um close the wire, but smaller exactly where the wire is.
  * Smallest gap: (50 , 60 ) um.
 * We tightened the clamps according to the specification: 10 Nm for the weight holding ones and 2 Nm for the locating ones.
  * 10 out of 12 screws rotated by small amounts when tightened, however,
  * The two screws of the locating clamp at the +Y side were completely loose.
 * After we re-assembled and released the payload we realized it had a lot of negative pitch (I wrote positive in the klog, sorry) and at least one OSEM flag was touching.
  * We corrected the pitch with the picomotor.
  * We also moved the BF keystone close to nominal position with the fishing rod.
  * Then we corrected IM yaw.
 * We found picomotor cables and stepper motor cables disconnected, so we connected them.
 * By the end of today's work the IM seemed to be hanging free.
 * We tried to measure TFs, but it seems the actuation is not going through because of a problem in the real-time model. Miyo-kun and Ikeda-san will take a look.
