Please note that the position and the use of the dead weights have a significant impact on the performance of the LA40 QR Damper. The most realistic test results can be obtained by using a real person as test subject on the application.
Dead weights can be used to test the LA40 QR Damper on the application, if the weight distribution of these on the frame is ensured to be as close as possible to the weight distribution of a person. Avoid unrealistic placing of the dead weights. This could for example be placing all dead weights on the top or middle part of the back frame. If doing so, retraction will be much faster.
Note that the dead weight will always have a faster lowering speed compared to person weight due to the different weight distribution on the bed frame's kinematic. Read more
