1. Immerse the microtip half way 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 as it may be damaged and it will not

vibrate properly.

2. The Ultrasonic Processor is now ready for continuous operation. To energize the

ultrasonics, press the START key or the footswitch. To de-energize the ultrasonics, press

the STOP key or release the footswitch. If the Time or Pulse functions must be used, refer

to the appropriate paragraphs below.

Note: The START key and footswitch are mutually exclusive. If the process is initiated by

the START key, the footswitch becomes inoperative. If the process is initiated by the

footswitch, the STOP key becomes inoperative.

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.

TIMER: In the pulsed mode the processing time will be different from the elapsed time because

the processing time function monitors and controls only the ON portion of the duty cycle. For

example, for 1 hour processing time, the elapsed time will be 2 hours if the ON and OFF cycle

are set for 1 second.

1. To set the processing time, press the TIMER key.

The screen will display:

2. Using the numeric keys, set the processing time as required, for example:

3. Press the ENTER/REVIEW key. The screen will display:
