What must be conducted before using the Intoxilyzer 9000 for BAC testing?

Before using the Intoxilyzer 9000 for blood alcohol concentration (BAC) testing, conducting a functionality check is essential to ensure that the device is operating properly. The functionality check allows the operator to verify that all systems of the Intoxilyzer are working as intended. This includes assessing whether the device can accurately measure BAC levels and that all components, such as the sensor and printers, are functioning correctly.

Conducting this check is vital for maintaining the integrity and reliability of the test results, as any malfunction could lead to inaccurate readings, potentially resulting in incorrect legal outcomes or unsafe driving situations. It ensures that the equipment is ready for use and complies with all necessary operational standards, thereby upholding the accuracy of the BAC tests performed.
