turbidity of water and waste-water. The meter covers a 0-1000 FTU range in two scales: 0.00 to 50.00 FTU and 50 to
1000 FTU. The auto-ranging feature of the instrument sets the appropriate range for the measurement.
A. Turn the meter on by pressing the ON/OFF key.
B. The meter will carry out a self-test displaying a full set of figures. After the test, the LCD will change to the

sample. Allow
sufficient time for bubbles to escape before securing the cap.
Note
Do not over tighten the cap.
E. Wipe the cuvette thoroughly with a lint-free tissue before inserting into the measurement cell. The cuvette
must be completely free of fingerprints and other oil or dirt, particularly in the area where the light goes
through (approximately the bottom 2 cm/1 inch of the cuvette).
F.
Place the cuvette into the cell and check that the notch on the cap is positioned securely into the groove.
G. The mark on the cuvette cap should point towards the LCD.
