strip pointing downwards.
Press the Test button to turn the meter off.

the bottle tightly.
Notes
The control solution you apply to a washable object must come
i
from a suspended drop. Do not use the drop if it has run down
the outside of the tip of the dropper. This may lead to results that
are too high.
Control solution that is to be drawn up by the test strip must just
i
have been freshly applied to the object. The control solution must
not be left exposed on the surface for any length of time, or it
may give results that are too high.
Results flagged as performance checks with the bottle symbol
i
are not included in the calculation of averages and lowest and
highest results.
