Span calibration procedure
Pouring a standard solution
1. Close the sample water valve and open the drain valve to drain the sample water
from the detector.
2.
Detach the automatic cleaner and clean the cell.
3.
Clean the inside of the cell of the detector thoroughly.
4. Prepare 200 mL of a span calibration liquid.
5.
Pour the span calibration liquid into the cell from the top to clean it.
6. Pour the span calibration liquid into the cell from the top again and wait until any
air bubbles disappear.
7. Switch the converter to the span calibration mode.
8.
In the meas mode, hold down CAL, then press  to display the span calibration
screen.
9.
Press ENT to display the span coefficient input screen.
10. Adjust the coefficient so that the turbidity measured matches the turbidity of span
solution. Then, press ENT to set it.
During span coefficient input, the numerical value continues blinking.
After the coefficient is set, return to the span calibration mode.
11. Hold down ESC to return to the meas mode.

SS adjustment (Coefficient setting menu)
When the unit is set to SS mg/L with Kaolin (Ptnb), you can change the measured value with
multiplying by a coefficient. This function allows you to adjust the output to the analyzed value
(refer to “ Coefficient input ” (page 39)).
Operation procedure
1.
Open SEnSor in the setting menu.
2. Select SiO (Kaolin) for standard material in tyPE (Calibration type).
3.
Press  to let it display coefficient.
4. Press ENT to start adjustment with  and press ENT to finish setting.
Hold down
