Type of ultrasound regulation [operating mode]
Here you can de
fi
ne whether the ultrasonic homogeniser should work with amplitude or power
control.
Ampl.
Amplitude control = constant amplitude
Thanks to the direct data logging in the ultrasonic transducer (AMPLICHRON
®
system), the
amplitude is precisely and quickly measured and set. In the process, the power output may
fl
uctuate based on the physical state of the medium.
Power
power control = constant power output
The control variable is calculated based on the measured electrical HF power, and has a
process-dependent time delay. Faster
fl
uctuations are balanced only on average. Depending
on the physical state of the medium, the amplitude may
fl
uctuate. This type of regulation
cannot be recommended for reproducible results.
Change display [display]
Here it can be choosed whether the accumulated energy (Energy) or the current ultrasonic
frequency (frequency) is displayed.
Sequencing [batch mode]
With this function (batch mode: on), there is an option for processing previously grouped
sonication programs. The con
fi
guration of a sonication program is described in chapter 3.3 and the
activation is described in chapter 3.4.
3.3
Loading / saving sonication programmes
The ultrasonic homogeniser possesses a working memory and 9 memory locations for sonication
programmes.
In order to work with a sonication programme, it must
fi
rst be loaded into the working memory. If
changes in the operating parameters are made in the working memory, a * (asterisk) will appear
after the programme number [Prog]. If these changes need to be available later as samples, the
current operating parameters may be saved on one of the 9 memory locations.
Memory management is called up with the keys "SET" and the arrow key .
