4.5.2.3 1 to 3 point calibration
Note: It is imperative to calibrate for solid matter measurement (refer to section 4.5.2 Calibration of
the SOLID (TS) parameter ).
Note: Before the sensor can be calibrated to the TS parameter, the parameter must be selected
(refer to
4.5.2.1 Select the SOLID (TS) parameter ).
1. Open the MAIN MENU.
2. Press SENSOR SETUP and confirm.
3. Select the corresponding sensor and confirm.
4. Press CALIBRATE and confirm.
5. Press CALIBRATE and confirm.
6. Press RECORD and confirm.
7. Press POINT... (point 1, 2 or 3) and confirm.
Note: Points 2 and 3 are not displayed 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 displayed
after the point or points that has (have) been recorded for approximately 3 seconds.
Note: If the Calibrate menu is closed before the calibration is complete and then called again,
the "<<" mark is displayed again. This shows that the calibration for this point or points has not
yet been completed. The old calibration values are still being used.
8. Remove a sample and determine the solid matter content in the laboratory.
9. Select the recorded POINT parameter and confirm.
10. Enter the laboratory comparison value and confirm.
To record more calibration points: repeat steps 6 to 10.
11. 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.

4.5.3.1 Delete recorded points
Points that have been saved with RECORD can be reset and deleted at any time.
1. Open the MAIN MENU.
2. Press SENSOR SETUP and confirm.
3. Select the corresponding sensor and confirm.
4. Press CALIBRATE and confirm.
