Immerse the electrode into the PH 6.86 solution (under 25Β°C) Then shake it gentle, and use the pen to test it. If it display 6.8, then the pen is good to use. If not, please use the screw to calibrate it (The hole in the back) , until the value is 6.8. Immerse the electrode into the PH 4.0 solution (under 25Β°C) Then shake it gentle, and use the pen to test it. If it display 4.0, then the pen is good to use. If not, please use the screw to calibrate it (The hole in the back) , until the value is 4.0. About PH meter using 1. Please be sure to keep the meter stable when using both of the two meters, do not shake them, or it'll affect the reading data. 2. Do not drop the entire meter in the water or dip beyond the maximum immersion line. 3. After using PH meter, you must clean the electrode and use filter paper to gently dry. Because inappropriate maintenance of the PH meter can result in unstable readings or damage, so we give some suggestion about the PH meter maintenance 1. Put the PH meter in the potassium chloride solution in order to keep it from mildew if you don't use for a long time. 2. Clean the glass electrode if you don't use the PH meter for a long time, the glass electrode will react with the oxygen in the air, and it will form a protective film and the PH meter's reading will be inaccurate. 3. Please ensure that there is no water in the PH meter after use, otherwise it will rust. Warm Tips Not use the PH meter for a long time will cause the the battery acid leakage, if you found this problem, please take photos and let us know after receiving the item in 7 days.
