Method for operating a dental ultrasonic device and dental ultrasonic device |
摘要 |
<p>The method involves determining the resonance frequency of the ultrasonic operation by a current and voltage measuring unit (10) for detection of an effective power. During the detection, the output power corresponds to the preset processing efficiency. The effective power is determined by average determination of the product of the momentary current and the momentary voltage.</p> |
