A wave function is used for calculating probability, but itself is not a probability.

However, like probability, a wave function is not a physical wave, which is located in physical space-time.

Like probability, a wave function is a mathematical tool that exists only in the conceptual space.

So, like probability, a wave function cannot be measured by any device.
