Transfer functions are running over the weekend on HAM2-ISI as well.
HAM2 was unlocked. It was a bit difficult the get the tight covers to stay away from the ISI without the rods we usually have (used on HAM3, see attached pictures). I added a couple clamps to keep the sheet in place over the weekend.
It looks like the covers rubbed against the ISI afterall. We need to take the cover rods from HAM3 chamber, put them on HAM2 and take a new set of measurements.
