S-D2 Operator’s Manual
is now ready to receive a breath sample from the subject
for analysis.
4) INSTRUCT THE SUBJECT
Instruct the subject exactly what must occur to provide a
suitable sample of breath for analysis. Tell the subject to
take a deep breath, blow strong enough to bring on light ‘A’
and keep blowing at that pressure long enough to bring on
light ‘B’. The subject must then continue blowing until
told to stop and you have taken the sample by pressing the
‘READ’ button. Warn the subject that if both sampling
lights fail to come on, there will not be a suitable sample of
breath for analysis.
If the subject blows too hard then he/she may run out of
breath before the ‘B’ light comes on: just a moderate
breath flow rate is required.
Finally, the subject should keep hands away from the
instrument. If the subject clasps it, your view of the
sampling lights or your operation of the sampling
mechanism could be obstructed .
5) TAKE SAMPLE
Tell the subject to take a deep breath and blow through the
wide-bore, lipped end of the mouthpiece. The subject
must blow strongly enough to bring on sampling light ‘A’
and then continue to blow at this pressure until the ‘B’ light
is activated. At this point, the subject will have expelled
top lung air so that deep lung air is now being blown
