For this solution to work smoothly, study the maximum amount of work that can be done at each step and the time interval to allow between steps.

The common frequency histogram method is not applicable to analyze the small sample data, because it is sensitive to the analysis parameters such as the starting point and the interval step.

To program the device, the user enters the start frequency, the increment step size, the number of increments to be made and the time interval the part stays at each frequency.
