8.4 Excessive time lag
Refer to
Figure 4
on page 11. Curve 3 shows a test that did not start with
sufficient bacteria during the incubation period. To do a test on a sample
without sufficient bacteria, seed the sample. Refer to the Seed the
sample section in the expanded version of this manual for more
information.
Bacteria acclimation also causes conditions that can cause curve 3. This
sometimes occurs with standards and added seed. Add more seed or
select a different seed source.
8.5 Sample temperature
Refer to
Figure 4
on page 11. The initial negative results of Curve
4 show that the initial sample temperature was below the specified range
of 20 ±1 ºC. A sample supersaturated with oxygen will also show this
type of curve. Refer to the Sample temperature and Supersaturation
sections in the expanded version of this manual for more information.
8.6 Bottle leak
Refer to
Figure 4
on page 11. Curve 5 shows a bottle leak. A bottle leak
makes the system unresponsive. If such a condition occurs, examine the
seal cup and bottle cap for contamination or damage.
