OR-UR / dilution
OR = Overrange / UR = Underrange
The test result is outside the measurement range of this method. OR results can be brought into
the measurement range by dilution. Use the dispensing pipette to take a 5 ml (or 1 ml) sample.
Fill the sample into the cuvette and add 5 ml (9 ml) of distilled water. Perform the measurement
and multiply the result by 2 (or 10). Dilution is not applicable to the parameter "pH".
