OPERATION
1. Connect AC power supply.
2. Connect the pH electrode, ORP electrode and TEMP electrode into relative electrode socket.
3. Remove the protective cap, clean the electrode with distilled water, put pH electrode, ORP 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. Clean 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. Clean 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.
ORP CALIBRATION
1. Immerse the meter in the distilled water. Activate it about some hours.
2. Immerse the meter in 265mV calibration solution(With quinhydrone reagent 4.01 calibration solution), and stir it gently.
3. Allow the reading to stabilize and with a small screwdriver turn the calibration trimmer until the display show “265”.
4. Rinse the electrode with distilled water and suck it with tissue paper.
