NORMAL MEASUREMENT
This type of measurement is best suited for regular readings, when the sample is stable and normal
accuracy is required. In normal mode, the measurement takes about 10 seconds and the lamp is ON
for a minimum period of time (about 7 seconds).
CONTINUOUS MEASUREMENT
This measurement mode is suitable when many measurements have to be taken in a short period of
time. The mode is useful to evaluate a very fast settling sample. This measurement mode is
recommended for indexing cuvets.
• Press “Read” functional key to take the
measurement.
The display will show “READ” in the left side
and blinking dashes. The dashes and lamp icon
will appear during different measurement
phases.
• The result is displayed in the selected units.
• Wipe the cuvet thoroughly with a lint-free cloth
to remove any fingerprints, dirt or water spots.
• Apply silicone oil on the cuvet and wipe with a
lint-free cloth to obtain an even film over the
entire surface of the cuvet.
Note: It is very important to oil the cuvet, espe-
cially for low turbidity values (< 1 NTU)
to hide the glass imperfections which can
influence the reading.
• Place the cuvet into the instrument. Align the
mark from the cuvet with the sign on the in-
strument top
• Close the lid.
Note: If you have a cuvet with indexing mark,
place the cuvet into the instrument with the
indexing mark aligned with the sign on the
instrument top.
