113 Considering different applications (high forces, low forces, pushing or pulling) the assembly follows slightly different paths. Generally, assembling the load frame can be broken down into these steps:
114
115 * Install a base plate on the rotation stage (use spacers, decide which plate to use)
116 * Mount load cell on base plate with desired pin or clamp (depending on push or pull experiments)
117 * Mount sample tube (choose the tube type according to your application)
118 * Mount pusher

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