1. Connect AC power supply. 2. Connect the pH electrode, TEMP electrode into relative electrode socket. 3. Remove the protective cap, clean the electrode with distilled water, put pH electrode, TDS electrode and temperature electrode into liquid which is to be test. And stir lightly, wait until the digital is stable, read the final value.
PH Calibration
1. Immerse the electrode in pH 6.86(under the temperature of 25℃ ) standard buffer solution of phosphate, and gently shake the electrode. 2. Regulate the pH7 trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained. 3. Cleaning the electrode. Immerse the electrode in the standard buffer solution of pH4.01. Regulate the pH4 trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained. 4. Cleaning the electrode.Immerse the electrode in the standard buffer solution of pH9.18 and gently stir until the display value is stable. If the error of display value is in the allowable range,then calibration is finished. If not, repeat 2.3.
TDS Calibration
1. Press "MODE” to choose “PPT” mode, then dip TDS electrode into 6.44PPT standard buffer solution, and shake lightly. 2. When the showing value is stable,adjust by bottom "PPT” until it shows 6.44PPT. Wash electrode in distilled water and dry it with filter paper. 3. Dip the device into 1382PPM standard solution, Press “MODE" to choose“PPM”mode When the showing value is stable, adjust by bottom “PPM” until it shows 1382PPM.
