In order to index a cuvette follow the next steps:

• Fill the cuvette with high quality water (<0.1

NTU) up to the 10 mL mark.

• Clean and oil the cuvette as described before.

• Turn the instrument ON.

• Insert the cuvette into the instrument and press

READ/TIMER u. Record the reading.

• Open the instrument lid, slightly rotate the

cuvette and take a new reading.

• Repeat the last step until you read the lowest

NTU value. Alternatively, keep the READ/

TIMER u pressed and, after the first value is

displayed, open the lid and start rotating the

cuvette until the lowest NTU value is displayed.

• Mark this position on the thicker white band on

the top of the cuvette with a water resistant

pencil.

• Always use this position to align it with the

sign on the instrument top.
