Compare the measurement result with the following specifications:

￭

Consumption (EP) [mL]:

1.95–2.05

￭

Potential jump [mV]:

deltaU

90–110%

 > 70 mV

￭

Titration time [s]:

approx. 150

NOTICE

If the measurement result does not correspond to the specifica-
tions, clean the electrode and run the test again. If titration
times are excessive, the stirring rate and the arrangement of the
stirrer, pipetting tip and electrode should be checked.
