INSTRUCTION MANUAL
• It is important that the sample does not contain any debris.
• Whenever the cuvette is placed into the measurement cell, it
must be dry outside, and completely free of fingerprints, oil and
dirt. Wipe it thoroughly with
HI731318
or a lint-free cloth prior
to insertion.
• Shaking the cuvette can generate bubbles, causing higher
readings. To obtain accurate measurements, remove such bubbles
by swirling or by gently tapping the cuvette.
• Do not let the reacted sample stand for too long after reagent
is added, as accuracy will be affected.
• After the reading it is important to immediately discard the
sample, otherwise the glass might become permanently stained.
