How does the Intoxilyzer 9000 ensure that the breath test is valid?

The Intoxilyzer 9000 ensures that breath tests are valid by performing automatic self-checks before and after testing. This procedure is crucial for maintaining the accuracy and reliability of the device. These self-checks are designed to assess the functionality and calibration of the machine, verifying that it is operating correctly and without any faults that could affect the results.

By implementing these automatic self-checks, the device ensures that any potential issues are detected and addressed immediately, contributing to the integrity of the testing process. This systematic approach helps to build confidence in the results obtained from the breath tests, as they are conducted under verified conditions, significantly reducing the chance of errors due to equipment malfunction.

In contrast, a continuous operation without any self-checks would leave the results vulnerable to inaccuracies, while requiring manual input solely from the operator may introduce human error. Similarly, locking out the device under certain conditions prevents testing under potentially unreliable circumstances but does not inherently validate the results themselves. Thus, the automatic self-checks serve as a vital component of the Intoxilyzer 9000's function to ensure valid testing outcomes.
