13.
Select the Tu sensor type from the drop-down list.
14.
The Number of Samples field is automatically set to 100.
This value is the number of sample points Ruskin will average to calculate the calibration coefficients
for the sensor. Typically, this value should be in the range of 50 to 100 samples.
15.
Click on a stable point in the Plot view corresponding to 0 NTU. In the table in the first row, under Real
Avg, enter 0 and press enter.
16.
Select the checkbox in the second row in the table, then click on a stable point in the Plot view
corresponding to the reading of your turbidity solution. In the table in the second row, under Real
Avg, enter the value of your turbidity solution and press enter.
17.
Ruskin automatically calculates the calibration coefficients, and the values appear in Calculated
coefficients. Clicking the Copy button saves the new calibration coefficients to the clipboard.
18.
Follow the steps
logger.
By using the above formula and changing the volume of distilled water and Formazin solution, you can
prepare different calibration points or different volumes for checking the linearity of the turbidity sensor or
getting close to real turbidity value of standard turbidity solution.
