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.
2.5 Scope of delivery

• TSS sc sensor
•  Protective cap for sensor tip (depending on model)
•  Test log
•  User manual
•  TSS sc wiper kit for 5 changes including screws and screwdriver (LZY634, optional)

2.6 Function test
After unpacking and checking for any transport damage, perform a brief function check.

1. Connect the sensor to the sc controller (refer to 3.3, page 15).
2. Switch on the power supply to the sc controller.
   The display is activated and the sensor enters measurement mode.
   Note: The measurement value that is shown in air is not relevant.
3. If no warning or error messages are shown, the function check is complete.

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

   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.
8. Select the recorded POINT and confirm.
9. Enter the laboratory comparison value and confirm.
   To record more calibration points, repeat steps 6 to 9.

   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.
