Women's Fitness & Figure, Master Women's (over 35), Senior Men, Bantam Light Weight, Welter Weight, Junior Men (under 21), Masters Men (over 40), Grand Masters Men (over 50), Middle Weight, Light Heavy Weight, Heavy Weight and Women's Bodybuilding Classes are included.

Equivalent circuit study trys to describe the impedance measured at a system under test by an equivalent circuit made up of electronic components. The components are often resistors, capacitors and inductors.

For a given circuit, the task is to find the optimal value for each circuit component, so that the equivalent circuit impedance function matches the measured impedance is good as possible.

With the WinFIT equivalent circuit analysis function, arbitrary models can be defined and the best set of values (parameters) is automatically detected. In addition, arbitrary components described by any complex impedance function can be defined.
