pH Meter/Conductometer
￭ Start the calibration with the key.
￭ Rinse the conductivity sensor with water and immerse it in the
first standard solution and then confirm with the key.
￭ The calibration temperature is measured with the connected tem-
perature sensor and added to the calibration data.
If no temperature sensor is connected, then the temperature has
to be entered manually.
￭ Enter the reference temperature for the standard solution.
￭ Enter the conductivity value of the standard solution at the refer-
ence temperature.
￭ Enter the coefficient for the current temperature and the selected
reference temperature for temperature compensation.
￭ Trigger the calibration with the standard solution with the
key.
2 Result of the calibration
￭ The result of the calibration (cell constant) is recorded and stored
for the respective sensor.
￭ Calibration is completed and the instrument will automatically
change back to the main dialog after 30 seconds.
NOTE
Limit values exceeded
If the calibration data is outside the limits defined as calibration
parameters, a corresponding message will be displayed.
You can then accept this calibration data nevertheless with the
key, or you can reject it with the key.

NOTE
Measured value criteria
You can set the various criteria for defining the measured value deter-
mination as follows (see Chapter 4.7.3, page 40):
