fwilde 8.1 112
fwilde 13.1 113 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:
fwilde 12.1 114
fwilde 13.1 115 * 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)
fwilde 12.1 118 * Mount pusher

fwilde 12.1 122 For the large load cell a specific base plate has to be used (see image)
