Following these procedures will eliminate mouth alcohol from producing
incorrect
readings.
Quantitative (direct) Testing
1.
With the unit turned on, attach a disposable mouthpiece onto the sample
port and use your finger, function buttons or stylus to select the icon for
quantitative testing.
NOTE:
To avoid potential contamination, be careful not to touch
the lipped end of the mouthpiece tube.
2.
The message ‘Air Blank Processing’ will be displayed which is a ‘blank’
(zero) test to ensure no residual alcohol is present within the instrument. If
alcohol is present at this point, attach a new mouthpiece tube and repeat
Step 1.
Once the ‘blank’ test result displays 0.0%, continue with step 3.
3.
If required, input subject’s information using the stylus pen or function buttons.
NOTE:
Maximum 16 characters for each input.
4.
When the touch screen displays ‘Please Blow’, instruct the subject to take a
deep breath, place / seal their lips around the mouthpiece tube and blow
steadily and constantly (not forcefully). If the subject is blowing hard enough,
a rapid (staccato) BEEP tone will sound. When this changes to a single,
constant BEEP, this is an indication that a successful sample has been taken,
and the subject should then stop blowing.
NOTE:
the subject should not hold the instrument during testing.
5.
The test result will be shown on the LED touch screen as
%BAC (Blood
Alcohol Content).
6.
If printer is being used, select
to print the test result.
7.
Select
to start another test.
8.
If the subject did not blow within 30 seconds, the tester can select ‘Refuse’ to
confirm the subject refused to conduct the test; or select ‘Test Again’ to allow
subject to do the test again.
9.
If the subject failed to give a valid breath sample the tester can select
“Discontinue” to confirm; or select ‘Test Again’ to allow the subject to repeat
the test.
10.
A passive test can be performed by selecting ‘Passive’ when the subject is
blowing.
