Step 6:
PAS Vr. Off
After noting/recording the peak reading, press the control button
again and release it immediately. The main display will turn off, and
the fuel cell will recover. Remove and dispose of the mouthpiece
.
Step 7:
Power Off
Turn power switch to the “off” position to conserve the battery
when the system is not in use for extended periods, e.g.,
overnight, weekends, etc.
Step 8:
Record Results
Record results into a suitable log; note the number of bars or the
numeric value (express results in terms of weight of alcohol (gm) per
volume of breath (liters)) of the bar-graph that light up, if any. If no
bars light up record "Negative for Detectable Levels of Breath
Alcohol" and have the subject initial the recorded results. If bars
light up indicating the concentration of alcohol, the employee if in the
commercial transportation industry must be given an Evidential
Breath Test (EBT) using a NHTSA/ D.O.T. approved EBT device.
Follow the manufacture
r’s instructions and D.O.T approved
procedures (49CFR Part 40) for conducting the EBT.
Note:
Give the subject exact instructions as to what he/she is required to do in order to provide a
suitable sample of breath for analysis. Tell the subject that he/she must fill his/her lungs and then blow
slowly but firmly, and continue to blow until you tell him/her to stop. Finally, tell the subject to keep
his/her hands down away from the instrument.
ATTACH MOUTHPIECE
Take a new PAS Vr. mouthpiece and check that the packaging is still intact.
IMPORTANT! Use only
the PAS Vr. mouthpieces; these are designed and produced for PAS Systems. Do Not
Substitute!
It is important the mouthpiece is attached to the instrument in such a way that your fingers
do not touch the actual blowing end, otherwise the subject may refuse to take it into his or her mouth on
the grounds of alleged lack of hygiene. Hold the mouthpiece, through the wrapper, between the thumb
and forefinger around the blowing end and peel or force the mouthpiece through the wrapper so as to
expose the small tip and about half of the barrel. Insert the tip into the sampling port on the right side of
the PAS Vr. instrument, then firmly seat. The mouthpiece body should fit positively into place and stay.
Having attached the mouthpiece, finally remove the wrapper from the blowing end, and dispose of it
properly. You may wish to retain the wrapper to remove the mouthpiece once the test is complete, and
dispose of the two items together, or you may ask the subject to remove their own mouthpiece by pulling
straight out.
