2.4 Measurement procedure
2.4.1 Procedure of measurements without the protective case
Components of the pH-meter must be available for operation according
to 2.3.
Prior to measurements open the electrode filling hole and remove the
protective cap.
Wash an electrode (electrodes) and temperature sensor in distilled water
and immerse into the analyzable solution. On pH measurements an electrode is to
be immersed in a solution at least 16 mm deep. Electrolyte level in an electrode on
measurements is to be above the analyzable solution level.
On pH or U measurements take readings after they have stabilized.
