Setting the monitor contrast [contrast]
With this function, the monitor contrast can be adapted to the local light conditions. The contrast
values range between 1 and 255, and can be set by turning the rotary knob. Smaller values result
in a darker image and larger values result in a lighter image. The default value is 190.
Type of ultrasound regulation [operating mode]

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. Only the average of larger
fl
uctuations is balanced. Depending
on the physical state of the medium, the amplitude may
fl
uctuate. This type of regulation
cannot be recommended for reproducible results.
