• At the end of the measurement, the instrument directly displays turbidity in NTU.
7.1. AVG (SIGNAL AVERAGE MODE)
It is recommanded to select this measurement mode when you work with unstable samples that
contain suspended particles of different dimensions.
In the AVG mode the instrument takes 20 measurements over a short period of time and displays the
updated averaged value.
To select the averaged measurement mode press the AVG key and the AVG icon will appear on
the LCD.
Note: to return to the normal measurement mode just press again the AVG key.
Press READ and “----” will blink on the display. After a few seconds the instrument displays the
first reading. The meter continues updating the readings until the “Lamp and Read Status” indicator
turns off. The final displayed value is the averaged reading of turbidity in NTU.
7.2. CONTINUOUS MEASUREMENT
This measurement mode can be used to verify how fast suspended parts settle out. Please verify that
the AVG mode is turned off (see instructions above). To make continuous measurement keep the
READ key pressed until the desired number of measurements are taken.
The last value remains on the display after the READ key has been released.
