Activating / deactivating the ultrasound
Ultrasonic operation can be started and stopped by pressing the “START/STOP” key or the key on
the ultrasonic transducer. Ultrasonic operation ends once the target time has elapsed (if a time has
been set), and a signal tone (long + short) is emitted. When the device is restarted, the displays
for the elapsed sonication time and for the energy are set to zero.
In contrast to stand-by mode, ultrasonic operation displays the actually achieved value in bar
graph form, in addition to the pre-set amplitude.
Please note:
Depending upon the physical conditions, i.e. the viscosity of the sonicated medium and the thus-
resulting control processes, a di
ff
erence between the target and the actual value, as well as a
fl
uctuating display, may occur.
The amplitude can be changed at any time during ultrasonic operation, using the rotary knob.
All other operating parameters can only be edited while in stand-by mode (see Chapter 3.2).
Notes:
• If the ultrasonic operation is manually interrupted before it reaches the activated target time, the
display values for the elapsed sonication time and for the energy will be saved and will continue
running upon restart. The display values can be reset to zero by pressing the “SET” key and
then pressing the “START/STOP” key.
• With the “non-stop” setting, the elapsed sonication time and energy must also be manually
reset, if needed. Once the maximum displayable time has been reached and exceeded, the
time display will start again at 00:00.
