OPERATION
Press the
I
key. The screen will display the power rating of the Ultrasonic Processor and the
following control parameters.
AMPLITUDE:
Desired amplitude must be set in order for the Ultrasonic Processor to be
operational. AMPL displays the amplitude selected (e.g. 40%). To set the amplitude at 40%
when the ultrasonics is off, press the AMPL key and the numeric keys for a 40% reading on the
screen, and then press the ENTER/REVIEW key.
Note: The minimum amplitude setting is 20%.
The screen will display:
1. Immerse the probe approximately halfway into the sample. If the probe is immersed to an
insufficient depth, air will be injected into the sample, causing the sample to foam. Also
ensure that the probe tip is not touching the wall of the sample vessel.
2. The Ultrasonic Processor is now ready for continuous operation. To energize the
ultrasonics, press the push button on the converter. To de-energize the ultrasonics, release
the push button on the converter.
3. 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.
REVIEW:
The REVIEW function provides a “window” on the process by displaying various
operating parameters without process interruption. Pressing the ENTER/REVIEW key
repeatedly during processing will consecutively display the following information.
