What must be the air blanks reading for a completed test?

• A. 0.020g/210L
• B. 0.000
• C. 0.050g/210L
• D. 0.100

Answer: (B)

For a completed test using the Intoxilyzer 9000, the air blank reading must be 0.000. The air blank serves as a baseline measurement to ensure that there are no residual alcohol or contaminants in the machine that could affect the accuracy of the test results. A reading of 0.000 indicates that the testing environment is free from such interferences, making the subsequent blood alcohol concentration (BAC) readings reliable and valid. If the air blank reading were higher than 0.000, it would suggest the presence of alcohol in the testing environment, necessitating a repeat of the air blank test until it meets the required criteria. Thus, having an air blank reading of 0.000 is crucial for confirming that the Intoxilyzer is functioning properly and providing accurate results.
