Note
1. Little or no amount of protective liquid in the electrode protective cover will make the electrode measurement value inaccurate.
2. When measuring alkaline ionized water (electrolytic water) and other water with a high content of calcium ions, calcium will be attached to the electrode, which will affect the sensitivity of the electrode.
3. Under normal use, magazines and minerals may be attached to the electrode, which may reduce the sensitivity and cause inaccurate measurements. Please use the supplied electrode cleaning sandpaper to clean the electrode.
4. Remove the protective cover from the electrode and gently wipe the electrode with the rough side of the electrode cleaning paper 2‑3 times when the electrode is wet with water.
5. Depending on the frequency of use, the electrodes should be replaced within one year.
6. All data are measured manually, and there are certain errors in the measurement results.
