3.5.4 Passive Testing
Passive testing is a test that is performed in a non-invasive manner and without using
mouthpieces. Passive testing on the LE5 can activated in one of two ways, either button
activated by the operator or pressure activated by the donor blowing.
A passive test by button activation is performed by holding the instrument 5 cm in front of
the test subject’s mouth, Press the Test Key and ask them to count or talk so that exhaled
breath may be picked up by the instrument and analysed for the presence of any alcohol.
Pressure Activated Passive is performed by holding the instrument approximately 5cm in
front of the test subject mouth and asking them to blow into the Passive Cup. The pressure
of the blow activates a passive test.
When using Passive Standard testing, a Mouthpiece test is automatically enabled, should
the instrument detect alcohol on the subject’s exhaled breath. Passive Only testing does not
prompt the user for further testing.
3.5.5 Enabling Passive Standard
If Passive standard mode has not been enabled, proceed as follows:
•With the screen displaying press to test, press the Up and Down buttons
simultaneously. The User Menu will be displayed.
