What should an operator do immediately after completing a breath test on the Intoxilyzer 8000?

After completing a breath test on the Intoxilyzer 8000, the operator should document the results and provide a copy of the test report. This step is crucial as it ensures that there is an official and accurate record of the test results, which can be used for legal and evidential purposes. Proper documentation helps maintain the integrity of the testing process and supports any subsequent legal actions or proceedings. Additionally, providing a copy of the test report to the subject is important for transparency and allows the individual to understand the results of the test conducted.

The other options may seem relevant but do not address the immediate procedural requirement after a test. Resetting the machine, while necessary for its operation, should not take precedence over documenting results. Contacting authorities is usually a follow-up action based on the outcome of the test rather than an immediate step. Managing tension with the subject could be important in a broader context, but it is not the primary action required after obtaining test results. Thus, documenting and providing the report stands out as the most critical next step following the completion of a breath test.
