2 Depending on the operating conditions and production tolerances as well as the probe types used, the actual value of the
resonance or ultrasonic frequency can deviate from the speci
fi
ed value.
3 Depending on the operating conditions and production tolerances, the actual value of the ultrasonic frequency can deviate from
the given value by +5 %/-7 %.

Frequency control:
The HF generator can perform automatic search of resonance frequency and frequency adjustment in an ongoing operation.
Reasons for changes of resonance frequency are, for example, heating of the ultrasonic converter and probe, change in acous-
tic load due to viscosity changes and also installation of another probe. Through the automatic frequency, a frequency drift
during operation is corrected. The optimal work frequency is found with the resonance frequency scan, such as after a probe
change.

HF power:
In the case of amplitude control, the HF power necessary for the desired probe amplitude is dependent on the viscosity of the
medium. To avoid damage to the HF generator and converter, the power is limited to the maximum permissible peak value. With
very viscous media, this can result in failure to reach the desired amplitude.
