2.3 Measuring principle
2.3.1 Turbidity according to DIN standards
Turbidity is measured in accordance with DIN standard EN 27027 (ISO 7027) and is calibrated by the manufacturer. Measurement is exceptionally simple and accurate.
2.3.2 Measurement of solids according to plant-specific curves
Software-based optimization routines enable extremely precise simulation of medium-specific calibration curves with few calibration points. Usually, a single calibration point is sufficient.
Up to three calibration points can be defined for a highly fluctuating medium. The combined multiple-beam alternating light technique records solids in the medium with even greater accuracy.

2.4 Handling
Do not subject the sensor to any hard mechanical impacts.

4.5 CALIBRATE
Note: Turbidity measurement has been calibrated by the manufacturer — it does not need to be calibrated again.
Note: It is imperative to calibrate for solid matter measurement (refer to section 4.5.2 Calibration of the SOLID (TS) parameter).
The zero point for turbidity and solid matter measurement has been set in the sensors by the manufacturer.
Installation conditions in the pipes can cause interfering ground reflection when measuring turbidity, which in turn may cause the zero point to shift. Compensate for this effect with an offset correction (section 4.5.1.3 OFFSET). If there are deviations that are unrelated to the factors described above between the measurement values shown and the laboratory results, the slope of the calibration curve can be adjusted using a factor (refer to section 4.5.1 Calibration of the TURBIDITY (TRB) parameter).
At least a 1-point calibration must be carried out for a solid matter measurement. In difficult application conditions, a 2-point or 3-point calibration may be necessary (refer to section 4.5.2 Calibration of the SOLID (TS) parameter).
4.5.1 Calibration of the TURBIDITY (TRB) parameter
Before the sensor can be calibrated to the TURBIDITY (TRB) parameter, the parameter must be selected.
4.5.1.1 Select the TURBIDITY (TRB) parameter

Open the·MAIN MENU.
Select SENSOR SETUP and confirm.
Select the corresponding sensor and confirm.
Select CONFIGURE and confirm.

Go back to the MAIN MENU or the measurement mode display.

4.5.1.3 OFFSET

Open the·MAIN MENU.
Select SENSOR SETUP and confirm.
Select the corresponding sensor and confirm.
Select CALIBRATE and confirm.
Press OFFSET and confirm.
Set the desired offset and confirm.
Go back to the MAIN MENU or the measurement mode display.

4.5.1.4 1 to 3-point calibration
Note: The turbidity measurement has been calibrated by the manufacturer.
Note: Before the sensor can be calibrated to the TRB parameter, the parameter must be selected (refer to 4.5.1.1 Select the TURBIDITY (TRB) parameter).

Open the·MAIN MENU.
Select SENSOR SETUP and confirm.
Select the corresponding sensor and confirm.
Select CALIBRATE and confirm.
Select CALIBRATE and confirm.
Select MEMORY and confirm.
Select POINT… (point 1, 2 or 3) and confirm.
Once the calibration point has been recorded by the probe, a mark “<<” is shown after the point or points that has/have been recorded for approximately 3 seconds.
Note: If the Calibrate menu is closed and then opened again before the calibration is complete, the “<<” mark is shown again. This indicates that the calibration for this point/these points has not yet been completed. The old calibration values are still being used.
Select the recorded POINT and confirm.
Enter the laboratory comparison value and confirm.
To record more calibration points, repeat steps 6 to 9.
Go back to the MAIN MENU or the measurement mode display.

The instrument automatically sorts the saved calibration points according to the size of the calibration values, irrespective of the sequence in which the calibration points were recorded.

Point 1 is always assigned to the smallest calibration value.
Point 2 is assigned to the next smallest calibration value.
Point 3 is assigned to the largest calibration value.

The value calculated in the laboratory can be corrected at any time by overwriting it.
4.5.2 Calibration of the SOLID (TS) parameter
Before the probe can be calibrated to the SOLID (TS) parameter, the parameter must be selected.

4.5.2.1 Select the SOLID (TS) parameter

Note: Points 2 and 3 are not shown unless point 1 or points 1 and 2 have already been recorded.
Note: This comparison is made from a grab sample and not a known standard.
Once the calibration point has been recorded by the probe, a mark “<<” is shown after the point or points that has/have been recorded for approximately 3 seconds.
Note: If the Calibrate menu is closed and then opened again before the calibration is complete, the “<<” mark is shown again. This indicates that the calibration for this point/these points has not yet been completed. The old calibration values are still being used.
Remove a sample and determine the solid matter content in the laboratory.
Select the recorded POINT and confirm.
Enter the laboratory comparison value and confirm.
To record more calibration points, repeat steps 6 to 10.
Go back to the MAIN MENU or the measurement mode display.

The instrument automatically sorts the saved calibration points according to the size of the calibration values, irrespective of the sequence in which the calibration points were recorded.

Point 1 is always assigned to the smallest calibration value.
Point 2 is assigned to the next smallest calibration value.
Point 3 is assigned to the largest calibration value.

The value calculated in the laboratory can be corrected at any time by overwriting it.
