"Entry of Solution" Calibration

(Calibration by entering the conductivity with display of the cell constant)
1) Press the Start softkey.
2) Immerse the sensor in the solution.
3) Enter the temperature-corrected conductivity value and press enter.
4) Finally, you can Apply these values or Cancel the calibration.

Cell Constant / Cell Factor Calibration

(Calibration by entering the cell constant (cell factor)
with display of the conductivity)
1) Press the Start softkey.
2) Immerse the sensor in the solution.
3) Modify the value of the cell factor (cell constant) until the temperature-corrected
conductivity value is reached. Then press enter.
4) Finally, you can Apply these values or Cancel the calibration.
Contacting conductivity sensor (conductive) Cell constant
SE 215 MS
Toroidal conductivity sensor (inductive)
SE 680 MS

Installation Factor Calibration

1) Make sure that the sensor is in normal mounting position in the medium.
2) Press the Start softkey.
3) Modify the installation factor until the correct conductivity value is displayed
(reference measurement). Then press enter.
4) Finally, you can Apply these values or Cancel the calibration.

Zero Calibration

1) Make sure that the sensor is outside the medium (in air).
2) Press the Start softkey.
3) Finally, you can Apply these values or Cancel the calibration.
Note: To abort calibration, you can press meas at any time.
