Calibration
The following refers to calibration of ID 111/112/113 (PTSA/Turbidity/Fluorescein):
As this Parameter uses an indirect light from above, it is essential to always ensure the
correct amount of water in the vial, which is why exactly 10 ml of liquid should be taken
when doing a test. To achieve this, use the pipette which is part of the Adapter-kit. Please
change or clean the tip of the pipette after each measurement/calibration using destilled
water.
Please perform a new calibration for the parameters of the ID111 / 112 / 113 if the
measurement results obtained appear to be inaccurate or no longer correspond to
the value of the standard solutions supplied.
