Applying Data on Changes in the Intensity of Optimal Measurement Conditions Checked with Intensity of Diffracted Light
Diffracted Light (Decay Process) Setting the following three parameters is required. The optimum parameters are selected using six levels of condition setting files.

In addition to the measurement results for particle size distributions, data on changes in the Application duration: 10 to 1,000 ms If the maximum intensity of the diffracted light is between these two lines, the measurement
Applied voltage: 5 to 35 Vpp
intensity of diffracted light (i.e., the decay process) can also be used. This data can be output to Frequency: 1 kHz to 1 MHz conditions are appropriate.
