The instruction listed below should be carefully followed during testing
to ensure best accuracy.
• Do not let the test sample stand too long after reagent is added or
accuracy will be lost.
• Whenever the cuvet is placed into the measurement cell, it must be
completely free of fingerprints, oil or dirt. Wipe it thoroughly with
HI 731318 or a lint-free cloth prior to insertion.
• It is important that the sample does not contain any debris. This
would corrupt the readings.
• Each time the cuvet is used, the cap must be tightened to the
same degree.
• It is possible to take multiple readings in a row, but it is
recommended that a zero reading be taken for each sample and
that the same cuvet is used for zeroing and measurement.
• It is important to discard the sample immediately after the
reading is taken because the glass might become permanently
stained.
• Shaking the cuvet can generate bubbles in the sample, causing
higher readings. To obtain accurate measurements, remove such
bubbles by swirling or by gently tapping the vial.
• All the reaction times reported in this manual are referred to
20°C (68°F). As a general rule of thumb, they should be doubled
at 10°C (50°F) and halved at 30°C (86°F).
