cup of distilled or deionized water, and rinse the electrode in it for a few seconds. Gently shake the probe to remove excess water, and dry it with clean tissue paper (DO NOT rub or wipe the probe, just use paper to dap off excess water). Gently stir the electrode for a few seconds after it’s dipped into the test solution and then let it stand still. - Page 12 points (see Table-5 for details).

to re-calibrate. For details, please see parameter setting P1.3 (Section 7.3) 5.3.6 pH Isothermal Measurement Principle According to the pH isothermal measurement principle, the closer the test sample’s temperature is to the calibration solution’s, the higher the accuracy of the measurement. This principle is recommended to follow when conducting tests for the best result. -

5.4.5 Take out pH electrode, rinse it in distilled water, dry it, and dip it into pH 10.01 buffer solution. Stir the solution gently and let it stand still in the buffer solution until a stable reading is reached. The meter’s display will show recognition process of calibration buffer solution at the bottom right of LCD. -
