The substrate is installed with a power key, a reset key and a setting key. The USB port is connected to an external computer for reading data in the memory. The sensor serves to measure the beating speed and force when a rod is swept; these data being displayed on the display. The beating speeds, acceleration curves, rhythms, forces, beating times, and consumer thermal powers are stored in the memory.
