3. polarity ements Connect the probe to the meter securely by aligning the pins p with the socket and pushing CPS the plug in Always remove the electrode on protective cap before use corr Make sure that the meter has is been calibrated before taking any measurements see calibration procedure Turn the instrument on by pressing the ON OFF key pH MEASUREMENTS If the electrode has been left dry soak the tip in a pH7 M10007 buffer solution for a few minutes to reactivate it Submerge the tip of the electrode into the sample to be measured select the pH mode and allow the reading to stabilize before taking measurements EC TDS MEASUREMENTS Immerse the tip of the electrode into the sample to be tested Select the measurement range EC or TDS and wait for the temperature sensor to reach thermal equilibrium with the samples before taking measurements AFTER MEASUREMENTS the instrument should be switched off and the probe cleaned and stored with a few drops of storage solution in the protective cap CALIBRATION PROCEDURE Remove the protective cap from the electrode Switch the meter on Select the range pressing the appropriate key for pH EC or TDS pH Calibration A PREPARATION Single point manual calibration Choose buffer If you are going to measure samples near pH 7 use pH 7 01 buffer solution M10007B for calibration use pH 4 01 buffer solution M10004B for acidic
