Storage temperature range is -25°C to 70°C, storage humidity is 15% to
90%. Incorrect storage of the device will shorten the lifespan of the fuel cell
sensor.
INTRODUCTION
CALIBRATION PERIOD
As per Australian Standard AS 3547-1997, calibration is required every 6-months
to ensure the electrochemical fuel cell is reading accurately. This calibration
requirement is time-based, not usage-based. This means that even if the device
has only had infrequent use during the 6-month period, calibration is still
necessary. Refer pg.12, section 4:i
Calibration

OPERATING INSTRUCTIONS
Pre-test Conditions
1.
Operating temperature range is -10°C to 50°C. Use within this temperature
range will limit condensation from a subject’s breath and ensure an accurate
reading from a breath sample.
2.
Mouth alcohol generally takes 10 – 12 minutes to disperse, so it is
recommended that the operator observe a subject for at least 20 minutes before
administering the breath test to ensure that nothing is consumed or expelled
from the mouth of the subject. This includes smoking, which should be avoided
for at least 5 minutes prior to testing.
3.
Blood alcohol concentration can continue to rise for up to 2 hours after the
cessation of drinking. A subsequent test may be required if alcohol is detected
or the result is close to the designated threshold.
4.
It can take 10 hours or more for the blood alcohol level to return to zero after a
high blood alcohol level has been reached. In such cases further testing
should be carried out later in the day or the following morning.
5.
When supplying a breath sample, the flow rate should be in the range 20-
30L/min
6.
It should be noted that many foods and some ‘non-alcoholic’ drinks may still
contain small traces of alcohol. The subject should also avoid drinking water as
water will cool the mouth and dilute saliva, which may temporarily reduce breath
alcohol
levels.
