Performing a Wet Calibration Check
Prepare the wet bath simulator according to its instructions on page 16.
Disconnect long tube from the output port. Attach a mouthpiece adapter securely to the
output port on the simulator lid. Refer to your simulator manual for location.
Turn the FC10 on. Attach a mouthpiece to the back of the unit.
Press the Function button until display reads “CALIBRATION,” then press the Execute
button. Display reads “WET CHECK”.
Verify the “CAL STANDARD” is set to the concentration of certifi ed alcohol solution you
will be using when you check the calibration. To select a new Calibration Standard, see
page 16.
Slide the FC10 mouthpiece over the mouthpiece adaptor on the simulator.
Be prepared to blow into the tube for up to 10 seconds.
Start blowing
• Blow through the input tube (or use a calibration pump) to create and maintain 1/2" of
bubbles on the surface of the solution.
• Press Execute to proceed and start a 3 second countdown.
• Press Execute to take a sample.
• Continue blowing for another 3 seconds.
Stop blowing
Read the result. It should be within +/- .005 BAC of the standard used. If your solution is
greater than .100 BAC, accurate results will be within +/- 5%.
Example:
• A .100 BAC solution should read between .095 and .105 BAC.
• A .200 BAC solution should read between .190 and .210 BAC.
If no alcohol was detected, the display will read “INVALID CHECK”. Repeat wet bath
calibration check instructions.
