Ultrasonic Test

4.8 Ultrasonic Test

The Test button on the front panel of the SLPt Cell Disruptor is used to verify that the unit is functioning
(providing ultrasonic energy to the Converter and Horn). Later, you can run another test on the system for
your particular experiment (described in 5.3 System Performance Benchmark).
Before testing the SLPt, always make sure that the horn is not touching anything. The System also performs
several self-tests when it is first turned on.
Step
Set up the SLPt Cell Disruptor follow-
1
ing the instructions in this manual.
Connect the microtip to the converter.
Connect the RF cable to the power
2
supply. Turn the Unit On, and observe
the self-test displays.
Adjust the Amplitude control to
3
approximately 50% (observe the
value on the front panel display).
Verify that the Horn is not touching
anything.
Press and hold the Test button on
4
the front panel. The test will run until
the test key is released. Observe the
front panel display.
If the system showed readings on
the display during the Test,
5
you may either proceed with your
experiments, or
Turn the unit off.
Use the following charts to determine the correct system settings for the tools you are using.

To obtain this result
Prepare the Sonifier to operate, if it was not previ-
ously assembled.
Verify that the system passes all its self-tests,
observing that there are no error messages on the
front panel display.
The SLPt Cell Disruptor advances to the "Ready"
mode and shows the normal Ready display .
Ensures that ultrasonic energy will be at some mid-
range value, and will not cause damage. Refer to
Table 4.3 for amplitude information.
Verifies the ultrasonic output of the system. You may
hear a soft, high-pitched sound.
Verification that the SLPt Cell Disruptor is operating
and is ready to be set up for your experiment.
