4.3.2 Calibration using reference solutions
The device is parameterised using the function keys on the display. The operating steps can be
found in the chapter "Calibration menu".
Please proceed as follows to perform a calibration using reference solutions:
1
Check that the device is set to the required measuring principle (absorption / turbidity).
2
Reset the calibration to the factory calibration ("rst") ( refer to
Reset to factory calibration
on
page 20) and save the reset by selecting "SAVE = Yes".
3
Prepare a table (see below the example) for 4 different reference solutions.
4
Enter the known values of the reference solutions in the target values of the table. The device
must show these values upon calibration.
5
Use the device to consecutively measure the reference solutions and enter the actual values
displayed by the device in the table. Avoid incorrect measurements by carrying over the solu-
tions, by flushing and thoroughly drying the instrument between the respective measure-
ments.
6
Transfer the values from the table into the device as follows:
- define the number of calibration points "cdef"
- enter the known target values of the calibration solutions "cj1...cj6"
- enter the determined actual values of the calibration solutions "cal1...cal6"
7
Confirm the entries by selecting "SAVE = Yes".
To check the calibration, re-submerge the sensor into the reference solutions. If the device
shows the target values, the calibration was successful.

SAVE
Saving the
calibration
no or yes
Saves and/or accepts the user calibration values and
overwrites the most recent calibration this way.
rst
Reset
no or yes
Reset to factory calibration, the user parameters are
maintained.
ESC

CAUTION!
Make sure that only authorised and trained personnel perform changes to the calibration.
INFORMATION!
Incorrect settings in the parameters may result in the output of incorrect measured values and
switching points.
