What might indicate an error during a breath alcohol test?

An error during a breath alcohol test can often be indicated by the appearance of error messages displayed on the Intoxilyzer 9000 screen. These messages serve as alerts for the operator, signaling that something has gone awry in the testing process, whether it be due to a technical malfunction, issues with the calibration of the device, or problems with the way the sample is being collected. Recognizing these error messages is crucial for ensuring the reliability and validity of the test results, as they guide the operator in determining the next steps to rectify the situation or to retest properly.

In contrast, increases in accuracy or consistent readings across multiple tests generally suggest that the device is functioning correctly. Furthermore, normal operational sounds from the device imply that it is running as intended, without any indication of malfunction or error. Hence, the key indicator of a potential issue during testing is the presence of error messages, which warrant immediate attention.
