Sample Measurement 4.4.1 Rinse the pH electrode in distilled water, dry it, and dip it into sample solution. Stir the solution gently and let it stand still in the sample solution until icon appears and stays on LCD, get the pH reading, which is pH value of sample solution, please refer to Figure-5 for calibration and measurement process of the pH meter. -

Returning to factory default setting is to restore the meter to the theoretical value (zero potential pH is 7.00, slope is 100%), and set all the parameters to default settings (see appendix 1). When the meter’s calibration or measurement is performing abnormally, users can use this function to let the meter return to factory default mode, and conduct calibration and then test again. -

electrode: (a) For inorganic pollutant, soak the electrode in 0.1mol/L dilute hydrochloric acid for 30 minutes, then wash it in distilled water, then soak it in the 3M KCL storage solution for 6 hours. (b) For organic or lipid pollutant, clean the platinum surface with detergent, then wash it in distilled water, then soak it in the 3M KCL storage solution for 6 hours. - Page 14 Table-8 Conductivity Calibration Solutions Calibration Icons Calibration Solutions 84 μS/cm 1413 μS/cm 12.88 mS/cm 111.8 mS/cm 6.2.2. How often to calibrate (a) The meter has been calibrated before leaving the factory and can generally be used right out of the box. (b) Normally perform calibration once per month.
