stay on the screen before pressing (c) To exit calibration mode and go back to measurement mode, press key. 4.4 Sample Test 4.4.1. Rinse pH electrode in distilled or deionized water, allow it to dry, and submerge it in tested solution. Stir the solution briefly and allow it to stay in the tested solution until icon stays on LCD and a stable reading is reached, which is the pH value of test solution. -

4.4.3. pH temperature principle Please note that the closer the temperature of the sample solution to the calibration solution, the more accurate the readings. 4.4.4. Factory default setting For factory default setting, please refer to parameter setting P1.4 (Item 7.3). All calibration data is deleted and the meter restores to the theory value (zero electric potential of pH is 7.00, the slope is 100%). -
