Measurement modules

Counter movement jump

The information about the person, jump type parameter and repetition sequence number is positioned at the top of the window. The Measurement tab displays the acquired signals as well as the selected cursors, and allows fine cursor positioning. The graph can be zoomed and viewed along auto-scaled or fixed Y axis. Visible plots are collected in the Plot list. By pressing the Offset button prior to the measurement, the input signal is set to zero. With the Trigger option unchecked, the signal acquisition starts immediately, while it is delayed until the force exceeds a pre-defined value if the Trigger option is selected. The acquisition terminates automatically when jump is completed, and the cursors are set instantly. Live signals switches between live acquisition and the last acquired signal.

The results of the analysis are displayed on the Results tab – in the Current column, which is updated when the T0 (start of moving) cursor is moved. Other columns contain the results of previously saved measurements. The Confirm button saves the parameters of the current jump, while the CMJ:SJ button opens a window where CMJ:SJ proportions can be calculated.
