4. To increase or decrease the amplitude in small increments when the ultrasonics is on,
depress the AMPL to display Amplitude Setting on the screen, then depress the ▲ or ▼
key, as required. Since the amplitude required is application dependent and subject to the
volume and composition of the sample, it is recommended that the amplitude be selected
through experimentation, by increasing or decreasing the level of intensity as needed to
properly process the sample to achieve desired results.
