7.6.1 Data input
Data input stands for the input of the specific values of the connected sensor, for example as determined at the
laboratory before.
Select the corresponding calibration value whose settings you want to change by. An input dialogue will now ena-
ble you to change the values within corresponding limits. If you exceed these you will get an error message to
prompt you to enter a value within the fixed limits.

This menu item enables you to set a temperature value offset.
Same procedure as temperature offset at
chapter „Calibration pH”.
7.6.3 Two-point Calibration
„Two point“
Calibrate the sensor at two separate points using two different defined calibration solutions or known set point
values. The calibration points are supposed to include the measuring range or the measured values to be ex-
pected, respectively. You can choose any sequence of the calibration solutions or set point values.
At first, you will be prompted to dip the sensor into the first calibration medium. After this step press
to ac-
cept the dialogue. Now, the currently measured value will be displayed. After the measured value has attained a
stable state, press
to accept the dialogue. You will now be prompted to enter the associated set point
value.

will now prompt you to dip the sensor into the second calibration medium. After you have accepted this, the cur-
rently measured value will, again, be displayed. Press
again to accept the stabilised measured value, be-
fore you will be prompted to enter the associated set point value. As a result, you will now be given the new cali-
