The measured mV value must not deviate by more than \u00b1 15 mV from the value stated on the bottle (at your temperature). If the value is outside this \u00b1 15 mV range, leave the electrode in the 220 mV standard solution for 15\u201330 minutes. This prepares the electrode surface for measurements and shortens the response time.
