NetterVibration has developed a new timer. The device called AP 117 allows adjustment of the duty cycle of its connected vibrators according to operational requirements. The advantage: There are no limits to subdividing work intervals exactly to the second. Thus vibration can be applied to fit the needs of operation. Short periods of vibration during the course of the day as well as long lasting vibration several times a day are only two of the many possibilities to adjust the AP 117.
