What does the term "calibration" refer to in the context of the Intoxilyzer 9000?

The term "calibration" in the context of the Intoxilyzer 9000 refers to the process of ensuring that the device provides accurate test results across different samples. Calibration involves comparing the device’s performance to a known standard and making necessary adjustments. This is essential for maintaining the reliability and accuracy of the breath alcohol measurements obtained from the device.

Accurate calibration ensures that the readings are consistent and reflect true blood alcohol content levels, which is critical for legal and enforcement purposes. When a device is not properly calibrated, it may yield false readings, which can lead to incorrect conclusions about a person's intoxication level. Therefore, maintaining the calibration of the Intoxilyzer 9000 is crucial for its effective use in law enforcement and public safety scenarios.

Cleaning the device or testing the battery life does not contribute to the accuracy of test results in the same way that calibration does, and adjusting the device's sensitivity is more specific to settings rather than the calibration process of ensuring standard accuracy across different measurements.
