Zsimpwin Tutorial Jun 2026

For those starting, installing the software and running your first automatic fit is an achievement in itself. ZSimpWin’s "Auto Setup" feature is designed to lower the barrier to entry, allowing you to focus on the physical meaning of your data rather than getting bogged down in mathematical algorithms.

When building or reading a circuit in ZSimpWin, use these standard symbols:

To select a model:

Click the Fit or Run button to let the software perform non-linear least squares fitting.
