Operation - Qsonica Sonicator Q500 Operation Manual

7.3. OPERATION

START UP: Press the ON 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. The other control parameters – Time and Pulse, do not have to be set for continuous
operation. AMPL displays the percentage of amplitude that was previously selected. 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. (Pressing the AMPL key
and the ▲ or ▼ key for a reading of 40% and then pressing the ENTER/REVIEW key, will also
achieve the same result.)
Note: The minimum amplitude setting is 20%.
The screen will display:
When working with a Microtip, do not operate the equipment beyond the maximum amplitude
limits listed below. Ignoring this caution will void the tip warranty.
Tapered Microtip:
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 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.
