What are the best practices for using a lie detector?

The lie detector's guidelines are unknown to me. If only I knew the proper way to use the lie detector. I would like to know more about how a lie detector should be used properly. I have a vague idea that lie detectors are used to identify dishonest people. How can a lie detector be used most efficiently and morally? I can't wait to learn from your perspective.

The best practises for using a lie detector are to ensure that the person being tested is familiar with the procedure and is aware of their rights before the test starts. It is important to have a qualified professional administer the test and to ensure that the person being tested has had adequate rest and is not under the influence of any drugs or alcohol. Additionally, the examiner should explain the purpose of the test and the potential consequences of the results. I give some of my experience.
