FC10 Subject Test Sequence

Observation:

Before administering the preliminary breath test, it must be determined that the subject has not smoked, regurgitated or placed anything in his/her mouth for at least 15 minutes prior to the test. Also check to ensure there are no signs of injury or blood in the subject’s mouth. This 15-minute period ensures any residual mouth alcohol that could possibly be left in the subject's mouth if the subject had just finished drinking prior to the test will not affect the results.

Preparation:

FC10 back view with mouthpiece port.

Step 1:

Attaching a mouthpiece:

  • Remove the mouthpiece from its wrapper, making sure not to touch the end the subject will be blowing into.
  • Attach the mouthpiece to the port on the back of the FC10. Line the mouthpiece port over the hole in the back of the mouthpiece and press firmly into place making sure it is fit tight.

Step 2:

Turning the FC10 on:

  • Press and hold the POWER button on the unit until a beep is heard. The FC10 will then perform an automatic internal diagnostic check, and if there are no problems it will soon display "AUTO TEST". 

Automatic Operation:

Step 3A:

Verify the display reads "AUTO TEST".

Step 4A:

Instruct the subject to blow into the mouthpiece for as long and steadily as they can.

  • It is not necessary for them to blow as hard as they can.
  • As the subject blows into the mouthpiece the FC10 will show a graph of the breath flow on the display, as well as show the number of liters. Liters are shown in the upper left corner. (See Figure A)

  • If the FC10 detects alcohol, the alcohol level is graphed and will be displayed before the results are shown. (See Figure B)

Step 5A:

Read the result displayed.

  • After taking the test, the FC10 will display the BrAC results.

Step 6A:

Remove the mouthpiece.

Note: The "AUTO TEST" may be overridden by pressing the "Execute" button while the subject is blowing into the instrument. This allows the completion of a test in the occasional instance when the subject may not be able to activate the automatic test feature.

Automatic operation is the easiest way to achieve a deep lung sample. The FC10 monitors the subject’s breath and automatically takes the sample near the end of the breath flow. 

Manual Operation:

Step 3B:

Verify the display reads "AUTO TEST".

Step 4B:

Press the "Function" button until the display reads "MANUAL TEST"

Step 5B:

Instruct the subject to blow into the mouthpiece for as long and steadily as they can.

  • It is not necessary for them to blow as hard as they can. 

Step 6B:

When the subject is near the end of their breath, press the "Execute" button.

  • After the "Execute" button is pressed, the FC10 will show a graph of the breath flow on the display.
  • If the FC10 detects alcohol, the alcohol level is graphed and will be displayed before the results are shown. 

Step 7B:

Read the result displayed.

Passive Operation:

Step 3C:

Verify the display reads "AUTO TEST".

Step 4C:

Press the "Function" button until the display reads "PASSIVE TEST".

Step 5C:

Hold the FC10 sample port, (orange colored opening labeled "Port" on the back of the FC10), about 4 inches from the subject’s mouth.

  • Have the subject blow towards the port. 

Step 6C:

While the subject is blowing towards the port, press the "Execute" button.

  • After the "Execute" button is pressed, the FC10 will only show a "POS" or "NEG" on the display indicating Positive or Negative for the presence of alcohol.
  • A passive test can be done over an open container to detect the presence of alcohol.
