4.3.3 Calibration using set of optical reference filters
Please proceed as follows to perform a calibration using set of optical reference
filters:
•
Check that the device is set to the required measuring principle (absorption / turbidity).
•
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".
•
Prepare a table (see below the example) for 2 different optical reference filters.
•
Enter the known values of the optical reference filters in the target values of the table. The
device must show these values upon calibration.
•
Use the device to consecutively measure the optical reference filters and enter the actual
values displayed by the device in the table.
•
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 optical reference filters "cj1...cj6"
enter the determined actual values with the optical reference filters "cal1...cal6"
•
Confirm the entries by selecting "SAVE = Yes".
