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.
