Sniffer test
–
allows the user to carry out a test using the Action Button
(AB) to fire the sampling system.
To carry out a sniffer test, select the sniffer test routine. If this routine
does not appear automatically you can scroll through the test types by
pressing the Down Button (DB) on any of the
“Ready” screens.
The sniffer test allows the operator to carry out a test without any
cooperation from the subject, and can also be used on a suspicious liquid.
The closer that the top of the instrument is to the subjec
t’s
exhaled breath
or the suspicious liquid the more reliable the result will be. Subjects who
have consumed alcohol will exhale alcohol in their breath, and liquids that
contain alcohol will emit alcohol fumes. This alcohol will be present in the
air, but will diffuse and become less concentrated the further away from
the source they are. The concentration of the fumes will also be
dependent upon the concentration of alcohol in the subject or liquid.
They will also be dispersed by environmental conditions such as wind and
rain.
This test is an indicative test and will only give a pass or fail result; it
should only be used to determine if there is alcohol present in the air
around suspicious subjects who are uncooperative, or suspicious liquids.
For more accurate testing it is recommended that a mouthpiece test is
carried out.
