107 Assembing the load frame can be brikne down into these steps:
108
109 * Install a base plate on the rotation stage (use spacers)
110 * Mount load cell onS base plate with desired pin or clamp
111 * Mount sample tube
112 * Mount pusher

115
116 For the large load cell a specific base plate has to be used (see image)
