Every examiner shall use an instrument which records permanently and simultaneously the subject’s cardiovascular, respiratory and galvanic skin response patterns as minimum standards and shall base his or her evaluation upon changes in such patterns. Such an instrument may record additional physiological patterns pertinent to the detection of deception. The examiner may also consider changes in such additional patterns in making his or her evaluations. An examiner shall, upon written request of a person examined, make known the results of such test to the person examined within 5 days of receipt of the written request.
