One big advantage of the mp-Labtronix controller is the possibility to set the whole range and combinations of all parameters:
Frequency: 1 – 300 Hz,
Amplitude: 1 – 250 Vpp; asymmetric
Three different wave forms: Sine, Rectangular, SRS
Using liquids, the signal form SRS should be used, a good starting point is 250V amplitude and 100 Hz frequency. For high viscous liquids, frequencies below 100 Hz are preferred, while for gases the frequency ranges above 100 Hz provide the best results. The optimal frequency needs to be determined individually. If the application is very sensitive to noise, the sine signal should be used instead.
