Calibration mode
1.If the electrode is kept dry for a long time, please insert the electrode into distilled water or pure water and soak it for 10 minutes to activate the electrode.
2. Pour 3 packs of calibrated powder (6.86 4.01 9.18) into 3 clean beakers, mark them, and dissolve them with 250ml distilled water or pure water respectively.The standard solution after use is not reusable.
3.Press ON/OFF to turn ON the power, insert the PH meter electrode into the 6.86 standard solution, gently stir it, hold still and wait for the value to be stable, press the CAL key for about 3 seconds, after the occurrence of the CAL character, release the CAL key, and the PH meter will automatically identify and calibrate the liquid value, and the value will stabilize to 6.86 after about 1 second.2 the SA character is displayed after the temple to indicate that the calibration result is being memorized, and then the END character is displayed, and the normal measurement is resumed after one second.
4. If the CAL key is pressed, the END character will be displayed one second later, which indicates that the buffer solution is invalid or the electrode is aging.Please confirm whether the buffer solution has failed and the electrode has aged.
5. Note: when the PH meter is calibrated, the END character is not displayed. Do not remove the PH meter from the buffer solution.
6. Calibrate 4.00 and 9.18 solutions in the same way as above.
Product maintenance
A.PH meter is a professional product. Non-professionals should operate under the guidance of professionals.
B. Before the first use, insert the electrode into distilled water or purified water and soak for about 10 minutes to activate the electrode.
C. please use the standard solution and correct operation method when calibrating the meter. Incorrect calibration will increase the measurement error!Do not press the CAL key during non-calibration, otherwise the program will be deranged.
D. Please do not insert the electrode too deep into the liquid when using, as long as the liquid can go through the electrode.
E. Store in a cool, ventilated and dark place.
F. Please do not test for thick and solid. This product can only test for flowing liquids.
