1. Install the 75 lb. (34 kg) weight set (refer to the previous section).
2. Align the dowel pins of the add-on plate labeled 100 lb. (45kg) and install onto the 75
lb. crosshead. Attach these plates with the two (2) 1/4-inch, 20 threads per inch x 1.0
inch (25mm) long socket-head cap screws.
Assembly Check-out
With lighter weights, lift the weights by hand to ensure that they glide easily up and
down on the guide columns. Alternatively, drop the crosshead from a known height and
verify that the velocity at the velocity detector is within a few percent <2% of the
theoretical value. Be sure to measure the drop height from the center line of the velocity
detector block to the second leading edge of the crosshead mounted flag.
