3.2.8 Impulse sound
The thermal effect can be altered by the selecting a different pulse ratio. The pulse ratio is the relationship
between the duration of the pulse and the cycle time. The cycle time for the standard 100-Hz pulse
frequency is 10 ms. If, therefore, the 1:5 pulse ratio is selected, the pulse duration will be 2 ms. The shorter
the pulse duration, the lower is the applied energy and the thermal effect.
With the
impulse sound key
a sound break can be set into certain pulse ratios. The
impulse sound frequency remains fixed.
The key is locked during the treatment.
