Step 4 – Test preparation
Mouthpiece Test – allows the user to carry out a test with a mouthpiece.
To carry out a test using a mouthpiece follow the following instructions.
Attach a new mouthpiece
The mouthpiece must be attached in a hygienic manner, or the subject
could justifiably object to putting it in their mouth. Tear open the wrapper
from the non-lipped end, and peel back far enough to expose the hole in
the side. Now, holding the mouthpiece through the wrapper around the
blowing (lipped) end, push the side hole over the lion alcolmeter® 700’s
sampling port, so it locks firmly into place. The operator may attach it
either way round, whichever is more convenient. Now remove the
wrapper completely (or have the subject do this himself).
