Difficulty: Moderately Easy
Things You’ll Need:
- Alcometer
- Fresh mouthpiece
- Subject
Step1
Press the "reset" button on the alcometer. This prepares the instrument's internal mechanisms for a sample.
Step2
Place the mouthpiece on the top of the alcometer and firmly push down. The mouthpiece must be attached to the alcometer to enable a sample to pass through and be analyzed.
Step3
Breath through the mouthpiece until the yellow light is illuminated. This indicates that the subject is blowing sufficiently to record a sample.
Step4
After a period of several seconds, the green light on the alcometer is illuminated. This indicates that the subject has supplied sufficient sample for analysis. Press the "read" button on the alcometer.
Step5
The alcometer will then display a digital readout of the blood alcohol concentration. On positive readings, the alcometer will continue to process while the "read" button is being pressed. The alcometer will eventually settle on a figure, indicating the subject's blood alcohol concentration as a percentage.
