Below are basic operation guidelines for the BACtrack SingleShot. For more detailed instructions and explanations, please read the BACtrack SingleShot Instructions.
Before you test:
- Read the instructions completely.
- Make sure the crystals are yellow before you test.
Wait 15 minutes after last alcoholic drink. If the test subject cannot wait, have subject drink water and rinse out mouth to remove alcohol vapors from mouth and esophagus that could cause a false positive.
Squeeze the middle of the detector between thumb and forefinger to break inner glass tube.
Squeeze only once--do not crush or bend tube. Use the detector immediately.
Hold vertically so arrows on the "BLOW" end are pointing down. Blow hard into tube one consecutive breath for 12 seconds. Shake the detector side to side to distribute the crystals evenly in detector window.
Lay detector on flat surface and wait two minutes.
Read the results.Positive Results: Most of crystals are a light AQUA (GREEN/BLUE, BLUE/GREEN) cast. This shows that the breath alcohol is at or above the level printed on the detector.
Negative Results: Most of the crystals, are light YELLOW. This shows that the breath alcohol is below the level printed on the detector. The yellow does not have to match the unused detector. It may be a much lighter or paler yellow than an unused detector.• The color change may be difficult to see under certain lighting. For best results, read under lighting such as incandescent, fluorescent, or indirect sunlight. A flashlight with an incandescent bulb can be used to help read the result. Hold the flashlight to the side so that the light does not fall directly on the detector.• Compare results to an unused detector or to the yellow box above. If most of the crystals are not GREEN or BLUE (under the suggested lighting), then the result is negative.• Detector results may not be reliable if testing is not conducted according to these instructions.
